You probably know that your online security is important. But are you using the right tools? Various online attacks target computers every minute of the day, and while standard antivirus tools are good, they’re not designed to cover every base.

The following free security tools will help you to improve your system and network security. You’ve probably never heard of them, but they’re vital to your ongoing online security.

Why Haven’t I Heard of These Tools?

You’re probably thinking, “I have an online security suite installed already, why do I need these tools?”

The answer is simple: online security suites can’t look after every single element of your computer’s security. Sure, they can deal with viruses, malware, firewalls, sometimes even ransomware, but overall, these tools are jacks of all trades, and master of none.

Whether you use an all-encompassing online security suite or nothing at all, it’s worth installing these tools and seeing how they can help you:

  • InSpectre: Checks your PC for the Spectre bug.
  • Angry IP Scanner: Checks your network for unauthorized access and bandwidth hogs.
  • Cybereason RansomFree: Scans your PC for ransomware activity.
  • Disconnect: Monitors incoming connections to your browser.
  • Malwarebytes Anti-Rootkit: Removes dangerous rootkits, and repairs the damage they cause.

Here’s what you need to know about each of these important tools and why you should be using them in addition to whatever security tools you’re already using.

1. InSpectre

Free Security Tools - InSpectre detects Spectre and Meltdown vulnerabilities in your CPU

You may have already heard about the Spectre and Meltdown bugs Meltdown and Spectre Leave Every CPU Vulnerable to Attack Meltdown and Spectre Leave Every CPU Vulnerable to Attack A huge security flaw with Intel CPUs has been uncovered. Meltdown and Spectre are two new vulnerabilities that affect the CPU. You ARE affected. What can you do about it?

In short, it’s a mess. While Microsoft has released its own tool for checking Spectre/Meltdown vulnerabilities, it’s a bit of a pain to use. That’s where InSpectre comes in, which was “designed to clarify every system’s current situation so that appropriate measures can be taken to update the system’s hardware and software for maximum security and performance.”

InSpectre is simple to use, and will tell you straight away if your CPU is vulnerable to either of the CPU bugs. Additionally, InSpectre informs you if the problem has been patched, or if an update is available. You can even disable protection, although that would seem to be unwise unless your system is suffering from particular performance issues. If disabling helps, it’s probably time to upgrade your hardware.

2. Angry IP Scanner

For instance, it will tell you what devices are on your network. If you suspect a neighbor of “wardriving What Is That Wardriving Thing All About? What Is That Wardriving Thing All About? Read More “, you’ll have the evidence. After all, it isn’t too difficult for a neighbor to pop around and sneak a look at your network key…

4. Disconnect

When you’re browsing the web, it isn’t only the sites you visit that attempt to communicate with your browser. Adverts, analytics, social networks, and more are also tracking you. With the Disconnect browser add-on, you can find out what is tracking you, and act upon it.

By visualizing and blocking sites that track you, Disconnect can make your browser 44 percent faster. More importantly, it can help you become more secure online. While we wouldn’t encourage that you block any adverts, Disconnect can block invisible trackers that aren’t affiliated with ad networks or social networks. These are the ones you need to beware of.

Disconnect features a graphical whitelisting option to ensure the content you want to see can still be downloaded. The same screen lets you block social network, and anonymous trackers.

    ‘Cybereason Ransom Free’ is AWFUL!! Caused nothing but problems on my Win 7 laptop. I emailed them numerous times and they did respond. Sent them logs, followed all their tips, but were unable to get it working properly. Then after uninstalling, using Revo. Deleting everything recommended, it still left crap all over my machine. Hidden folders (fake canary files), left over ‘Cyberfree’ entries all over the registry even though I used its own uninstaller and Revo. It got rid of some files, & reg entries. I still had to spend hours getting rid of all the left over ‘hidden’ mess. Unacceptable!!! When you have a program available for public use, at least make your software engineers remove the program and it’s remnants completely. I know most programs leave a reg entry or 2, but this was 20-25. Stay away! Disconnect and Malawarebytes are good. The other responder is correct that the normal program includes a ‘rootkit scanner’. No need for a specific program.

    I have tried "Angry IP Scanner" now, but I'm running "Advanced IP Scanner" which picks up more connection and device descriptions and runs without Java.

    Malwarebytes Anti-malware has a built-in rootkit scanner, so no need for Malwarebytes Rootkit scanner. Better use Malwarebytes Antimalware and enable "scan for rootkits".

    It hurt to read this. This story must have been researched and written in less than five minutes. Four minutes of writing. Low effort.
