My wife’s got a little Toshiba netbook running Windows 7, and when she opened up Mozilla Firefox she immediately got a warning suggesting that she do a complete scan.
Immediately, one positive (Win32:Trojan-gen) came up which i sent to the virus chest. Then another, from AdobeARMhelper.exe that wouldn’t let me send it to the chest, or repair, or delete or anything.
deactivate your file system shield now and do not re-activate it until the next update is available. There’s a false positive disaster going on right now.
