There might be times when your desktop antivirus has turned a zombie, rendered practically useless by some trojan or a virus. The possibility of such a thing happening is very rare, but still having an option to cross check is always good. An online virus scanner should never be considered a substitute for an installed antivirus scanner. But if you suspect your installed desktop antivirus is missing a threat or you simply want a second opinion, an online scanner can be a valuable adjunct to security. The list below introduces some of the best online antivirus services and is in no particular order.
