Is the background downloader a virus?

According to MVP Schwick on the EU forums, several different anti-virus scanners have started detecting the Blizzard background downloader and some patch files as malware. With as much trouble as you can get into with certain kinds of malware, this sort of alert would be bound to panic anyone. However, this one has been confirmed by Blizzard as a false alarm. For now, be sure to download the latest updates to your anti-virus scanner, and if it detects any of the following, it's likely a false positive:

• Trojan-PSW.Win32.WOW

• R/PSW.WOW.RG.3

• Trojan horse PSW.Generic4.TUV

However, if, after upgrading your anti-virus software, you're still getting virus messages? Report it on the tech support forums. As Blizzard EU rep Torzelyn says:

Updating the Virus Scanners is removing the Trojan alert, but if your particular scanner is still flagging it as a trojan, please don't patch the game just yet. I'm sorry but I'm just wanting to be cautious. Although it appears to be a false positive, as with Kaspersky, AntiVir etc.. updating the definitions is solving the problem, I don't want to just say 'use the files' because there could still be a problem somewhere.
