0. ClamAV - Free Antivirus App For Businesses
ClamAV for Windows has just released a beta of version 3.0 of its software, and it's well worth a look for corporate users on a budget.
The virus-scanning engine is provided by ClamAV, a stalwart of open source AV defenses, especially on server systems. The virus definitions are provided by both ClamAV and the Immunet Protect, a cloud-based community project that relies on ‘collective immunity'--users submitting suspicious files for analysis.
The key new feature in version 3 is offline scanning. Because of its cloud nature, ClamAV for Windows ideally requires an Internet connection in order to check files against virus definitions, but with version 3 the ClamAV engine and virus definitions are also held locally, so virus scans are possible when the Internet isn't present.
Perhaps ironically, one of the things I tend to do if the Internet goes down is to perform full virus scans, bearing in mind there's usually little else I can do, so this is a useful feature.
1. Comodo Antivirus / Internet Security
The free version of Immunet antivirus doesn’t have any restriction in usage at all. You can use it for both personal and commercial purposes at any place including office, servers, education facilities and etc. You can find this statement on ClamAV’s FAQ webpage question number 4. Both ClamAV and Immunet have been acquired by SourceFire which is why you’re seeing Immunet’s FAQ posted on ClamAV’s website.
3. NANO Antivirus
NANO Antivirus can be used without any restrictions and this information is posted at their website in License Agreement page.
4. Microsoft Security Essentials (Partial)
Many people would have thought that Microsoft Security Essentials is free to use without any limitations as long as the Windows operating system is genuinely licensed but unfortunately their licensing terms say differently. According to the first point in the Microsoft Security Essentials license terms page that is posted on their website, you are only allowed to use the software on up to 10 computers if you operate a small business. MSE usage in Government or academic institutions is restricted.
5. UnThreat Antivirus
UnThreat Antivirus EULA didn’t contain very clear terms of usage stating that their free antivirus can be used on commercial. We’ve contacted them using their official contact form asking them if their free antivirus can be used used for corporate, commercial or educational facilities. 5 days later we received a reply from them confirming that the “free version of UnThreat, may be used without any licensing fees”. Please see screenshot below for proof.
