Everytime I try and download a file in IE 9, I get a message that "filename contained a virus and was deleted". This started about 3 weeks ago. The same thing happens in Firefox, except there's no message - the file just shows as downloading and then disappears at the end of the download. I'm running Vista Home Premium 64-bit, with all current updates (although I don't think the OS is the problem) and MSE as my AV software. These files are good downloads and do not have a virus (downloaded elsewhere and checked). Anyone have any idea why this is happening? Thanks.
