I am running WindowsXP Home edition.
I've never really had to post on any forums asking for assistance with WindowsXP, but I am completely stumped at this point. Yesterday I downloaded AVG, because I was suspicious that my current anti-virus software wasn't working correctly, or wasn't filtering out viruses properly, my suspicions were correct. I found some virus in a suspicious file called 'svchost..exe'. I played around with winsock32.dll, kernel32.dll and shell32.dll to try to get rid of the virus manually. Needless to say, it screwed my internet connection up. I tried reinstalling the dll's from recovery console but no luck, so I repaired Windows (by reinstalling all of the system files with the WindowsXP disc). Afterwards I log on to my computer everything works fine for a while. So I decide to just delete the strange svchost..exe file, and everything still works fine and dandy, nor is it protected by Windows or being used. I run Hijack this! and to my surprise I find:
O4 - HKCU\..\Run: [explorer.exe] C:\WINDOWS\system32\svchost..exe
I delete it using Hijack This! as I'm sure many people would have done... then I download Windows XP Service Pack 3 RC 2, install it, and right as it finishes installing a message pops up: Access is denied. So I run regedt32.exe, change my permissions and try later, still the same problem. So it uninstalls itself and restarts my computer without asking. Upon boot up, my username password has changed, so I start up in safe mode. When I reach safe mode my start bar at the bottom is gone... so I use ctrl+alt+delete to run CMD and change the password of my username to what it was before... I restart my computer and log in as myself and the start bar is still missing. I can't drag or drop files unless I use CMD to copy/move. Half of my programs won't start up including Windows Defender and Firefox. When I navigate to system restore with file browser and I try to run it I get an error message, "System Restore is not able to protect your computer. Please restart your computer and run System Restore again." (Of course I could restart my computer 100 times and it still wouldn't work). So, in order to try last resorts I do "sfc /scannow" and "chkdsk /f" I also make a copy of svchost.exe and rename it to svchost..exe with CMD. None of those efforts were able to repair the problem. So, I load up my WindowsXP disc again, and reinstall Windows... again... I start up knowing well, "surely, reinstalling Windows will fix this problem," I was wrong. I log on to my username and I still have no start bar and half of my programs still won't load. I am officially out of ideas, and I'm guessing the problem has something to do with deleting that svchost..exe with Hijack This!
Please help. Thanks a lot to anyone who makes an effort .
