Jotti's Malware Scan: Online virus scanner

Nothing really beats a good firewall or anti-malware program that offers real-time protection. But if something was going to come close, we'd say a tool that lets you check files against 20 different antivirus might come close. Jotti's Malware Scan is an online tool that lets you upload a file and scan it with 20 different antivirus tools including Avast, ClamAV, and Kaspersky.

Note that there's a big ole warning on the site letting users know that just because Jotti's Malware Scan says a file is clean doesn't mean it's safe to run that executable file you found on BitTorrent that promises to show nude pictures of Billy Ray Cyrus -- wait, no, that's not the person people are looking for naked photos of, is it? Anyway, this warning message was probably placed on the site to point out that the developers take no responsibility for any problems you may have with files scanned. But in general, we'd say that if you feel the need to scan a file with 20 different antivirus applications, you probably already know that you shouldn't be opening it.
