hello all. i have run into a dilemma. i have important files on my system, so want to repair the install, as opposed to restoring from an image, or reinstalling.
i have Windows 7 x64 on a single raid disk (single because is already setup when i buy more disks). this system has been operation for more than 6 months.
i had avg=-x64 free, it had some errors last week(first time i have ever seen this), so i removed it, and installed m$security essentials. after a few days i got a virus and or trojan, maybe vundo, from running a program fix that was cleverly disguised. i tried scanning with MSE to no avail. so i removed the deadbeat program and reinstalled avg-x64 free .
in the recent past, the pc started to exihibit some symptoms. after boot, and after splash screen, it would stay on a black screen for about 30 seconds while hard drive thrashed incessantly, then the login screen would finally come up. this is the main symptom that bugged me enough to run the scans. i also had checked the windows firewall, and i cant get into that, its kicking back errors and wont let me access some stuff across my network. looks like the virus had a field day.
so after putting back on avg-x64 free, i updated and ran scan, and installed/updated malwarebytes and ran scan. it found stuff, i removed them, restarted. i thought teh system was clean eventhough still thrashing like mad, the next day i ran them again it found more stuff, and removed them. a couple of them were registry entries, a couple of them were just game files found bad. nothing really in the system directory which you would expect to see with a virus. one of the things i noted to be the virus was a file called mse or msde in the user appdata temp folder, then onto the system32 or syswow64 folder.
now on the last run of the virus scan, it rebooted, but it wont make it past the splash screen. this is where i am stuck.
what i have done
i have ran system repair several times, and i manually ran sfc /scannow a couple times, and chkdsk /f /x.
i started to run kaspersky 10, but i saw that it has problems completely manglind raid arrays, so i avoided that.
i have tried to start in safe mode several times, same symptom after splash screen goes black, then reboots.
i have tried booting in logging mode,
i have tried booting in command prompt, the last driver is loads is ahcix64s.sys, it thrashes for a bit, then restarts,
i have tried to load last known good configuration, and it restarts after splash screen goes black as well.
one more thing, i have system restore turned off since im a virus remover kind of guy, not a m$ dependent kind of guy, but i think this has shown that system restore is needed on Windows 7 more than xp.
