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.
Top 10 Free Online Virus Scanners
1. Kaspersky Free online virus scan

Trend Micro’s Housecall is one of the few tools in our Top 10 Online Scanners to offer cleaning or deleting of infected files. If you are being attacked by popular viruses, than you need to scan your PC with Trend Micro Housecall. This scanner easily finds and kills popular viruses. But on the other hand, rare viruses usually aren’t found by this scanner and Trojan horses escape too. Updates and detection are not quite as reliable as the Kaspersky options above. Select Housecall only if cleaning or deletion is desired.
VirSCAN.org is another free online scan service, which will check the uploaded files for viruses, trojans, backdoors, spyware and other malware using different antivirus engines.
