there are some tools which offer online virus scan for the files..
for free of cost well cheq these sites for online virus scan
# TREND MICRO : 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 “Housecall” and Trojan horses escape too. “Rootkits” has even bigger chance to hide from this program.

# F-SECURE : No virus will survive against F-Secure. Program perfectly kills viruses, Trojan horses and backdoor programs. Spyware and rootkits has a better chance to hide from F-Secure, that's why I also recommend scanning your PC with an anti-spyware.
You should use Internet Explorer, because other browsers are not supported. If you are using Firefox 2, you can install an extension, which is called “IE tab”. It will make F-Secure think, that you are using IE.

# PANDA: “Panda” scanner will save us from popular viruses. Another good thing is that it scans our e-mail too. But on the other hand, this scanner doesn't perfectly detect Trojans and backdoors.

# Windows Live OneCare Safety Scanner: That is the only one scanner, which works with Windows Vista. It perfectly detects popular viruses, but most of the spyware, Trojans, rootkits and other pests were not detected. And we also need Internet Explorer to use Windows Live Scanner.

# Softwin Bitdefender Online Scanner: It kills all popular viruses, but most of other pests were not detected. I recommend this scanner only if you don't have many free HDD space, because this scanner needs only 13 MB.

# Symantec Security Check :“Symantec Security Check” is the worst online scanner. It perfectly detects viruses, Trojans and spyware, but the problem is that to remove any pests, you need to buy an ordinary anti-virus.
