So I was using my computer like any normal day and avast pops up saying it found win32:virtob-gen infected numerous .exe files. So since it found numerous virus'\ i decided to reboot and do a bootscan. Well not really thinking I decided to choose the delete all function for the problems it finds. I leave my computer and come back a few hours later and its all done. It reboots and goes to load windows. It gets to the logon screen where it has my username. When I put my password in and try to load windows it starts to load. There is a few second pause with a blank screen and then the little I guess loading windows pop up block comes back up and says logging off. I tried logging in safe mode and its teh same thing. I have my hard drive partitioned and have about 50gb's worth of music and movies that I don't have backed up (I know, wrong answer).

What I'm wondering is, do I need to reinstall Windows XP Home? And if I do can I keep the partition and all the information on the partitioned drive? I had one partion with 15gb's that I kept windows and all programs on and then one with 65gb's that I had all my media on. Thanks for any and all the help.

Let's try to roll back the registry from Recovery Console. ( Thanks Wannabe1)
Boot from the Windows XP installation CD...after the first several screens load, you will be given a choice to choose R for Recovery Console[. You will then be asked to log in. Choose the installation to be repaired by number (usually 1)...yours will likely be different as we want the old installation, perhaps 2...and press "Enter". When you are asked for the Administrator password, leave it blank and press "Enter".

When you get to the recovery console prompt:

* Type cd \ and press "Enter".
* Type cd system~1\_resto~1 and press "Enter".
* Type dir and press "Enter".

After you press enter you will see a list of folders (like rp1, rp2) If the list of restore points has more than one page then press the "Enter" key until you reach the end of the list

* Type cd rp {number of the second to last folder in the list} and press "Enter". (Example: Type cd rp9 if rp10 is the last restore point.)
* Type cd snapshot and press "Enter".
* Type copy _registry_machine_system c:\windows\system32\config\system and press "Enter".
* Type copy _registry_machine_software c:\windows\system32\config\software and press "Enter".
* Type exit and press "Enter".

Your PC will reboot.

If you get an access denied error when doing the above, then do the following at the recovery console:

* Type cd \ and press "Enter".
* Type cd windows\system32\config and press "Enter".
* Type ren system system.bak and press "Enter".
* Type exit and press "Enter".

Your PC will reboot, go back into the Recovery Console and start from the beginning.

If you run into a problem or have a question, please ask before proceeding with any given step

sorry for such the long delay. i did this as described. ran into a slight problem so i think. after i did this step:

* Type copy _registry_machine_system c:\windows\system32\config\system and press "Enter".
* Type copy _registry_machine_software c:\windows\system32\config\software and press "Enter".
* Type exit and press "Enter".

the computer rebooted and then went to the screen where it says there was a problem when your computer shut down. boot in safe mode, etc etc. i chose start windows normally and then the windows boot screen came up. it did was appeared to be its normal thing and then the screen went black. the computer was thinking for a minute and then stopped on this black screen. i tried ctrl alt del and nothing appeared to be working. i really dont want to lose the data on my hdd. any other help? thanks in advance!

I assume after the roll back you tried safe mode.
You have 2 options left
1) We try a windows repair - should leave data intact. Programs like office, games etc will have to be reloaded.
2) We try a parallel install - should leave data intact. Programs like office, games etc will have to be reloaded.

Do you have all your programs?
Cheers
