This isn't my first time here :-/ I was here maybe two months ago with a WinXP Defender bug. Well either it was hiding somewhere or I was wrong about where I picked it up and got it again, because it came back with a vengeance. I first noticed it Sunday morning and after some preliminary cleaning looked like it was gone, but then I discovered it had brought a google redirect with it. And I'm thinking that redirected me somewhere where I picked up something worse, because now I cannot open most common filetypes: PDF, DOC, XLS, TXT, PNG, JPG (and presumably others) all give me some variation on "Access is denied" or "User does not have privileges" when I try to open them, copy them, or move them. I can delete them. Security settings on the documents indicate that I should have full access. Note: This does not seem to apply to *new* files, so I can get to my scan logs. FWIW, I had the 'access is denied' glitch on txt files previously but I was able to get around it by choosing "open with." I have completed the 8 steps (well, haven't got around to reinstalling java yet but the old version is gone). Before that I also tried a few antivirus programs recommended by other sites: Hitman Pro, TDSSkiller, Kaspersky Virus Removal Tool 2010... all to no avail Symptom recap: - WinXP Defender pop-ups (now gone) - Google Redirect (still have it) - Trying to open some programs or installers presented message "X is not a valid win32 application" (now gone) - Kaspersky VRT2010 recognizes it as Rootkit.Win32.TDSS.d but cannot disinfect - Bluescreened twice trying to run GMER: "A problem has been detected and Windows has been shut down to prevent damage to your computer" DRIVER_IRQL_NOTLESS_OR_EQUAL, then PFN_LIST_CORRUPT - Cannot open or move basic file types (most important to me) - Randomly opens additional tabs in firefox Please help, I'm in over my head (again) Logs attached HijackThis log will not attach properly -- the attachment manager window tells me the connection to the server is reset. Had to zip it.
