Despite the fact that Windows 7 and Windows 10 are the most popular operating systems on the market, Windows XP is still installed on some computers, for a various number of reasons. A statistics about the Windows XP usage can be found in this article.
Today I’m going to list a few free (at least free for personal use) and lightweight antivirus software than can still run on Windows XP, without making it.
From my experience, the best antivirus for Windows XP is Avast, having a lot of features, including:
- On access protection against viruses and malware
- Heuristics engine to detect previously unknown threats
- Silent mode which hides alerts during full-screen user activities
- Easy installation wizard.
- It requires yearly registration.
- It suggests installing additional software
Comodo Antivirus Free provides virus protection and on-access file protection, includes a Game Mode that does not display any notifications, updates virus definitions in the background and has both 32 bit and 64 bit installers.
- Performs some system modifications that you might want to disable
- Initial updates take a while to complete
- The installer kit is very large
- In creates a sandboxed environment for untrusted apps, not permitting them to infect the system
AVG free is yet another antivirus system that can run on older computers that use Windows XP. It provides file anti-virus, anti-malware and anti-rootkit protection, web protection, email client protection, can be used in silent mode, can be controlled via a web portal and does not ask for registration before usage.
- It slows down the computer
- It installs third-party software by default
- It recommends the acquisition of paid features
- The Zen interface may be annoying
Last but not least on this list is Immunet, yet another free antivirus still compatible with Windows XP running on older computers.
- It is very light
- Provides cloud-based anti-virus, anti-malware and anti keylogger protection
- Can run along other antivirus system
- Does not provide a very good protection
