You’ve heard it a thousand times: you need antivirus protection. Macs need it 5 Easy Ways to Infect Your Mac With Malware 5 Easy Ways to Infect Your Mac With Malware You might think it's pretty difficult to infect your Mac with malware, but there are always exceptions. Here are five ways you can get your computer dirty. Read More . Windows PCs need it. Linux machines need it. Modern antivirus apps have gotten so easy to download and run that you barely need to do anything at all. Plus you can get some of the best ones for free. You really have no excuse. So grab one of these ten and start protecting your computer!

A Note About Free Antivirus

All of these companies are trying to make money. And handing out free antivirus isn’t going to do that. So there are a few things you should be aware of. Many of these companies, for example, will try to get you to upgrade to their paid software. You might see pop-ups or get emails telling you to upgrade. That’s one of the costs of free software.

More insidiously, some of them will try to get you to install free toolbars 4 Annoying Browser Toolbars & How To Get Rid Of Them 4 Annoying Browser Toolbars & How To Get Rid Of Them Browser toolbars just don't seem to go away.

Just keep an eye out when you’re downloading and installing these apps, and be prepared to occasional nagging to upgrade. If you’re prepared for it, it won’t be much of an issue.

Avira (Windows, Mac)

With a reputation for consistently solid performance and easy-to-use tools, Avira is a great choice. The most recent antivirus test from AV-Comparatives gave the pro version a 99.9% protection rate, and you can bet the free version packs similar power.

Bitdefender (Windows)

Another antivirus app whose pro version got a 99.9% protection rate, the free version of Bitdefender will keep you safe from almost every piece of malware in circulation.

The simple interface won’t overwhelm you with options, and automation means you don’t have to actively manage it. It was also designed to be light on system resources, which is a bonus, as some antivirus apps can be resource hogs.

Avast (Windows, Mac)

Although Avast secured a slightly lower protection rating than some other options (99.6%), it’s still very high. It has also has relatively low resource usage, making it unlikely to noticeably slow down your computer.

avast-free

A simple, easy-to-use interface means you don’t need an instruction manual to get it set up. Despite ranking slightly lower on threat protection, Avast is a solid choice for anyone looking for a free antivirus. There’s a reason it’s one of the most popular options out there.

AVG (Windows, Mac)

Another free antivirus app that’s been very popular for a long time, AVG ranks well in both protection (99.6%) and system resource usage. And while they now offer unnecessary things like system cleanup and mobile antivirus, their core product is still one of the best.

avg-free

AVG does have a reputation for some annoying nag screens, but many people find the occasional upgrade request an easy price to pay for solid antivirus performance.

Lavasoft Ad-Aware Free (Windows)

Lavasoft’s pro version of Ad-Aware scored a 99.3% protection rate in recent tests, making it a solid contender. And while that version did tend to use more resources than other antivirus options, it’s still a great choice for Windows users. Its focus on anti-adware and anti-spyware features are especially nice.

ad-aware

And although using a free antivirus app is going to be sufficient for just about everyone, the various paid levels of Ad-Aware are quite affordable, so if you’re looking to upgrade to something more fully featured, sticking with Lavasoft will be easy.

eScan Anti-Virus Toolkit (Windows)

This toolkit differs from the other options available in that it doesn’t require an installation; you can just download and run it. That means it can be run from a USB drive, and you can use it even if you already have another antivirus running. It never hurts to have backup!

escan

Because there’s no installation, there’s no real-time defense or scheduling. So you probably shouldn’t use this as your main antivirus. But if you think yours might not be working, or you want to double-check, it’s a good choice.

Trend Micro HouseCall (Windows, Mac)

Another on-demand antivirus app, HouseCall can be quickly downloaded and run. It won’t give you scheduling options or real-time protection, but if you think your computer might be infected I Think My Mac Has A Virus! 3 Ways You Can Tell I Think My Mac Has A Virus! 3 Ways You Can Tell Is your Mac acting kind of... weird?

Malwarebytes Anti-Malware (Windows, Mac)

Malwarebytes has earned a strong reputation for excellence over the past few years. And its anti-malware app is no exception. It specializes in getting rid of adware, it’s a very small file, and it’s lightning-fast.

malwarebytes-free

Unless you decide to upgrade, you’ll only get manual scan capabilities, and no real-time protection. But even with that caveat, it’s still a great app to have.

Download Malwarebytes for Windows (note: download the free trial; you can continue using the basic features after the 14-day trial expires)

Panda Free Anti-Virus (Windows)

While you’ll probably get quite a few nag screens telling you to upgrade to a paid version, Panda does have some advantages. For example, it offloads most of its work to the cloud, freeing up system resources.

Beyond doing work in the cloud, there’s not a whole lot to differentiate Panda from other things out there. AV-Test showed that it protects well but doesn’t have phenomenal performance results. It did score very well for usability, though, so you don’t need to worry about complex interfaces and configurations.

ZoneAlarm Free Anti-Virus (Windows)

This is quite a full-featured app for being free. In addition to all the standard antivirus features you’d come to expect, it also packs a basic firewall 5 Reasons Why You Should Use a Firewall 5 Reasons Why You Should Use a Firewall You've heard of firewalls, but what are they really for?

There’s a good chance you already have one, but it certainly doesn’t hurt. It also offers some basic identity protection that will let you know if there are unauthorized changes to your credit files.

Using an actual identity theft protection service (or even basic credit monitoring) will likely be more effective, but another layer of security is always good.

    Hi,
    I am using Emsisoft Anti-Malware, and Emsisoft Emergency Kit together with HitmanPro......
    They are free, and also available, in a payed version.....(Emsisoft also available for Android)
    HitmanPro is a second opinion anti-malware, forensics-based and cloud-assisted.
    I have to say, that I am very happy with them, using Emsisoft in the free version,
    and HitmanPro in the free, and payed version.
    They helped me out a view times, and I like them a lot.
    Try them out..!!

    Great list. I have always used some kind of antivirus, but since I have some important data and files on my computer I decided to get something that will prevent losing it. I think that malware and ransomware are quite dangerous I wanted software that will focus on protecting computer against them. A friend of mine got one too, and he recommended me Impedio Security. It is relatively new, but it really makes a great job in protecting files and data! They do offer a free trial and it is really worth to give this software a shot.

    I've used a lot of these at one time or another. AVG and Avast use dto be my favorites, but they've become bloated, or as to install upgraded (paid) programs.

    My work started using Sophos as it's corporate solution this year. I realized they had a free version, so I installed it on my home PCs, and it just works, without being intrusive. I highly recommend it.

    • Dann Albright
      April 22, 2017 at 3:10 pm

      I've used Sophos before, and I didn't have any problems with it. It tends to get slightly lower ratings in tests than the others, but if you're on a newer computer that has plenty of memory, it should be totally fine. Thanks for the recommendation!

      Well, you're certainly welcome to not protect your computer. That's totally up to you. But if you can find one that has minimal system performance impact (as most of those listed above have), it seems like a pretty low-stakes decision.

    This is the kind of ill-researched article that misguides readers and leads them to install things like AVG, whose preponderance of search engine and browser hijackers, annoying upgrade notifications, and coaxing the user to install its useless snake oil computer optimization software, makes it almost as bad as the badware it's supposed to protect you from.

    Whoever the author of this article is, shame of your your lack of research and your obvious attempt to limit you're so-called "Top" antivirus programs to freeware.

    Do you realize that viruses have not been a problem on the Web since the early 2000's? Malware, ransomware, PUPs, hijackers are the kinds of things users encounter every day on the Internet. Not on of your so-called top picks protect users effectively against any of those

    Next time you write an article, please do some research - specifically personal research. Don't use google to look at other reviews then paraphrase what's already been written.

      February 6, 2017 at 7:05 pm

      This article was purposefully limited to free antivirus options. You obviously missed the title, but it says "free" in it, so that's why there are no paid options. Obviously paid options are going to be better.

      Also, next time you comment on an article, please do some reading - MalwareBytes' option is specifically anti-malware, and is one of the top-rated solutions based on detection, removal, and usability. You probably skipped down to the comments without reading that one.

    People who use Avast need to be aware of something: "To detect malware and threats on HTTPS sites, Avast must remove the SSL certificate and add its self-generated certificate." If you trust Avast, this is all well and good, but if Avast ever gets hacked, their users are in trouble. The only way I found out about this was because Agilebits.com, the maker of 1Password, wouldn't open with Avast web shield enabled. You can read more about it here: https://discussions.agilebits.com/discussion/comment/264053/#Comment_264053.

    • Dann Albright
      February 6, 2017 at 7:07 pm

      Thanks for pointing that out; definitely something to be aware of. Hopefully Avast never suffers a successful attack. The likelihood of that happening seems pretty low, but it's definitely something to be aware of!

    I dropped AVG a few months ago when they revealed they would start collecting user data to monetize it. I replaced it with Avast, only to find out a few weeks later that Avast was purchasing AVG in order to get its technology.

    I've heard that Microsoft Security Essentials (which was rolled into Windows Defender for Windows 10) had crept out of last place, becoming a poor antivirus instead of an incredibly terrible one.

    • Dann Albright
      February 6, 2017 at 7:06 pm

      Yeah, both Avast and AVG can be bothersome to some people for privacy reasons. It's a tough compromise to make, but if you'd rather not use them, there are plenty of other options out there. Avast does have a great user interface, though, so some people might find it worth it.

    Dear ACR

    Aren't you pleased with yourself... So pleased in fact that you didn't get the irony of "Common Sense 2011." Oh yes indeed, probably just as lame...

    I'm sure you're very good at fixing the machine's of the poor people forced to use your service but the average user will benefit far more if they can prevent malware etc, in the first place. I too fix people's PC's (on a "non-professional" basis) and try never to wipe and reinstall but the idea is to help people, not boast about how great you are... The average user really doesn't care HOW their PC works, they just want to know that it does what they want it to and does so safely.

    Mark, I have ben AVG fan for a long time as well. But then I discovered
    that Avira is much more effective. There were couple of times when AVG
    failed to detect stuff that I knew was infected.

    Avira's detection rate is very high.

    Call me boring if you want but I have ALWAYS used AVG Free. I always like to try new apps on the computer but for some reason, AVG has always been the virus checker for me. Nothing else has really "clicked" with me (no pun intended).

    Comodo does indeed offer protection from malware, they had a separate application called boclean which was free anti malware which is now part of CIS, I can also assume that they are one of only a few free anti virus suites which offers protection from buffer overflows and sandboxes untrusted applications - sure it isn't the simplest to use but the level of protection it offers is second to none - and yes, it can be used in a corporate environment. The latest version 4 wasn't even used in this review for some reason! they're using 3.6 or something like that.

    I was a fan of AVG since about version 6, but now that program is so bloated and taxes my system so much that I have switched to Avira. I'm the kind of person that likes to be in control of everything on my computer. If I want to terminate a program it should be my choice. Avg took over my computer and wouldn't terminate even if I wanted it to, so it had to go. It may be a good feature for some, but one thing I don't like about AVG (and Avira even) is when I open up my file browser, each file in the folder I'm viewing is scanned, no exception.. with no way to turn that feature off.. slowing down my system and overworking my cpu. If I wanted to scan, I'd initiate a scan. I don't need software taking over and slowing things down.

    Avast, MBAM, & Combofix are best free "AV" programs in your list. AVG is horrific in a business environment (think network issues galore). Avira is a joke... did you really publish that and MSE? really MSE is junk, believe me. ClamWin = Junk, Comodo = Junk, Common Sense 2011 = what? probably just as lame.

    Do you have any real experience supporting of end users infected with viruses? It's our specialty... we never format & reinstall. We fix the problem. We use Avast, Panda, Dr. Web, Spybot S&D, SAS, MBAM, Combofix, & SAV32CLI. If you really know what you're doing you'll script them from CD and run it in safe mode with command prompt. We change dir to the cd drive and run bentleypc.bat... then move on to the next computer. If that don't do it, we hook the drive up to a linux box and run Avast Linux on it (doesnt work after updates anymore, please fix this dear avast developers; ok?).

    If that don't do it, we manually remove the virus by seeking and destroying files & registry keys associated with the infection. Yeah it takes a long time. No, we're not going to format an accountants pc and reinstall Quickbooks 1999 - 2010, scanners, printers, office, all the millions of addons they need & about 30 other suites of software... that takes too long.

      Dear ACR

      Aren't you pleased with yourself... So pleased in fact that you didn't get the irony of "Common Sense 2011." Oh yes indeed, probably just as lame...

      I'm sure you're very good at fixing the machine's of the poor people forced to use your service but the average user will benefit far more if they can prevent malware etc, in the first place. I too fix people's PC's (on a "non-professional" basis) and try never to wipe and reinstall but the idea is to help people, not boast about how great you are... The average user really doesn't care HOW their PC works, they just want to know that it does what they want it to and does so safely.

    I use Avira for Anti-virus Comodo for firewall & Emsissoft A Square for malware and Trojan and spy-bot and Malwarebites also Comodo's hijack-this.
    Avira and Comodo & Spy Bot are the front end or real-time scans, and one's a week I run A Square and Malwarebites for a clean system never had a problem and I run 7 different OS.
    XP pro 32 bit, XP pro 64 bit, and win7 64 bit, the other are UNIX base so then I just use Clam Av just for the mail.
    Sense Unix & Linux dose not have this problems, there is no need to use anything else.

    April 14, 2010 at 9:51 pm

    I agree with you and use the exact same setup. Have MSE as my main AV and MBAM free installed and updated, scanning once in 2 weeks or if something doesn't clean up with MSE.

    Although CommonSense 2011 prevails most of the time :P

    I use avira. Both avira and avast were rated really high by av comparatives (which touts itself as being an unbiased site). Now, admittedly, they used the premium version of said programs, but they're still really good free virus scanners. Top it off with comodo firewall and spybot s&d... Although I am tempted to try malwarebytes...

        Can someone advise re: Malwarebytes? I have installed it and regularly update it (at least 2x/week) and scan my computer. Yet, it never finds anything. By contrast, I run scans with AVG (most often) or AdAware and find tracking cookies by the dozens. Any ideas why MWB doesn't ever seem to find anything?

        • KH
          January 23, 2017 at 4:02 pm

          Malwarebytes is primarily anti-malware. It states on the site that you should use antivirus, too I didn't like it; it is like malware itself. It invades your computer and is tough to uninstall First time I tried to uninstall it, it shut the computer down like it was mad

  76. sianz
    April 14, 2010 at 7:38 pm

    no to avira, its nag-ware... i ended up switching to avast. also, for comodo, the firewall module is still unstable (at time of writing) i'm running win7-64.

    i would stay away from those 2.

    I can't believe you people actually rely on Microsoft Security Essentials.

    Do yourself a favor and pull down the free version of Prevx (or use Trend Micro's Free online scanner) and take a look at what Microsoft Security Essentials may be missing on your system.

    I care for 17 small business networks and have tried several times (unsuccessfully) to use Microsoft Security Essentials on customers laptops and home PCs. It ALWAYS results in an infection of some sort within 30 days of installation.

    It really saddens me to see Microsoft Security Essentials fail so miserably at keeping people safe. I mean, if Microsoft can't keep their own operating system safe, how does that make their users feel?

    I'm pretty sure Common Sense 2011 is an absolute must. It tells me to to stick with Linux.

    However, I was fixing a Vista machine a couple weeks ago and between Clamwin, SuperAntispyware, Spybot, and CCleaner (all portable apps), it was cleaned, but there were unfixed problems left even after the virus was gone. When all else failed, I resorted to the sledgehammer of fixers: Trend Micro's HijackThis. Even if an antivirus gets rid of a virus, some major problems can be left behind from it, such as altered hosts files, IE helper objects, etc. HijackThis fixes the problems that a virus can cause and security apps ignore. It's not pretty, user friendly, or safe for people that don't know what they're doing.
