Using the trial version of Prevx 3.0. I noticed several days ago of a reported infection of file "testbundle23w_1254.exe" stored a folder where IE keeps its cached files. Of course the trial won't clean the file, so I just deleted the IE cache manually. Now today I get a new warning about the same infected file "testbundle23w_1254.exe" in the same location as last time. So this time I went to the specified location "c:\users\xxxxx\appdata\local\microsoft\windows\temporary internet files\content.ie5\5dsvuv73\" so I could manually delete it. Problem is, the "\content.ie5" directory doesn't exist. The supposed parent folder contains only a few files and no sub-folders. It's not a hidden directory either. I assume Prevx gives this occasional false positive in order to induce people to upgrade to the full version that will clean an infection that they don't really have. I have experience with windows going back to 1994, and though it's possible that I missed something, this is really what it looks like to me. If so, that's some pretty shady work.
