My friend doesn’t have the Internet and most of the free antivirus programs require a connection for updates. Avast asks for registration as well. Is there a free antivirus that can be used offline?
Avast is the best but u should be updated otherwise AVG is nice
Most computers without online access tend to make frequent use of USB drives. Unfortunately, USB drives are one of the more common ways to pickup a virus, particularly for an offline computer.
Here's a great article, by Varun Kashyap, on how to disable the autorun feature for USB on Windows:
I think for any user who needs protection from Viruses and other computer threats should go for the best antivirus. I have been using Quick Heal Total Security for more than 3 years now and I never had an opportunity to worry about the protection of my computer. Quick Heal has brought me a complete peace of mind.
u wont need an anti virus if theres no internet connection

Commodo Antivirus with Internet security... It's free
Avast is the best antivirus in all terms.You can register it offline by going to its site and registering it.They'll send you registration key in your email.Moreover,you can download monthly offline update.
okay this question better answer by fellow "offline" user also. just like me.. here i suggest use off avira antivirus free.http://www.filehippo.com/download_antivir/
install in opt out all internet required like toolbar n other service. the go here to download the manual vdf update file http://www.softpedia.com/dyn-search.php?search_term=avira+vdf&x=0&y=0
u just need to type the keyword "avira vdf" at search if the file definition if older since i put this link today. when u install the main antivr program. run it with double click at quick link or the desktop shortcut. when the main window open, go to "update" tab click n choose manual update n when the popup windows appears search the vdf file that u download manualy earliaer. the click n let the system do next. all u need to do id click "ok" along the process if any popup appears n cancel at the ads popup windows.
there u go... it the best free antivr for offline user like us that sometime go to cyber cafe or office to use the internet. it will autoupdate itself but if u well know about it just go to extras tab n click configuration tab. when the popup apears just set the time to zero i think in the latest antivr program. it will disable the auto update. or just let it be n all u need to do is click ok when the update failed popup apear
Most AV software provides a way to update them offline. Avast!, Avira, AVG, MSE all provide a way to download new virus definitions and apply them offline. I don't know if they still do it, but Avast! used to have a way to get a registration code through their website and then apply it to another computer that was not connected. If they do, it is not at the same page and it does not auto-redirect (end up with a 404 error). MSE requires their Genuine Advantage check on initial install. With version 3, there was a way to cheat this, but it is overly complex and does not always work depending on other services & software on the machine. I was able to do it twice, but it also failed on 2 other systems and I haven't been able to isoloate why.
Because of the size of the definition files and the frequency of updates, using Clam as suggested by Fidelis is probably your best bet.
Windows Defender Offline
Microsoft Security Essentials
I personally recommend Avast free antivirus as its always Good, user friendly and obviously very lite n will not bulk ur machine... Js download it for free from http://www.avast.com but you should regularly update your virus defination for ur machine's safety!!!
Hello, if you only needed for offline use I would say one of the best options you have is to use a portable app such as Clam antivirus. Keep it in a flashdrive and keep it updated whenever you have online connection. Here is the link:
I would recommend security essentials but in your case it would not work because it needs internet connection to validate your operating system. You could try avast, but you have to register it and also you would have to get manual updates whenever there is connnection.
