Hi, I recently had a bad computer virus which trend micro picked up as troj_vb.fad. The exe dropped into system file something called PEditor.exe (packet editor) but also with it was the troj_vb.fad virus. This virus popped up with a fake box called Windows File Protection with nothing but a blank box and blank tab boxes. It also stopped the run and task manager, after I restarted cuz the comp locked up (bad move I already knew) I tried going into safe mode but the comp wouldnt start up saying missing or corrupt hal.dll and ntoskernel.exe files. After doing a recovery and windows repair I got all the way back to the welcome screen but cant log in because when I type my password in itll start to barely load up showing the background pic I put it to then immediatly logs back out and the Turn Off Computer now displays Turn Off Mine. I really dont wanna wipe if I dont have too. Any ideas?

You may be able to use a Windows XP bootable Floppy Disk to boot from a diskette instead of your hard drive. If your hard drive's boot sector or Windows' basic boot files have been corrupted, this disk will circumvent the problem and boot you into Windows. If you don't have an emergency boot floppy, you may be able to use one created on another PC running Windows XP but there's no guarantee that it will boot your machine.

Another option is to create a Bootable CD:
Bart's way to create bootable CD-Roms
Creating a bootable Windows XP CD with Nero Burning ROM
Creating bootable Windows 2000/XP/2003 Disc with Nero 6

Some types of malware can result in a system so badly damaged that a Repair Install will NOT help!. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards and may still be responsible for your inability to boot properly. Starting over, reformatting the drive and performing a clean install removes everything.

Reformatting a hard disk deletes all data. Since you cannot access your computer one option is to is to remove your hard drive, install a new one, and make the old one a "slave". That way you should be able to access it and salvage some of your data files.

Well I know all of that, I can do all of that if it came down to reformatting. What im trying to figure out is if anyone has dealt with this virus and have been able to fix the computer/clean it without having to reformat it. My computer boots up after I did a windows xp recovery, only problem is I cant get past the windows xp welcome screen. I have one account which is password protected, when I put the password in it starts loading up then immediately logs back out and im back to the welcome screen. All I want to know is if my computer is fixable without a reformat, and if so what virus scanner/cleaner do I need because trend micro is the only one that has found it but since I cant log into it I cant do a full scan. Im going to try slaving my computer with an old harddrive and try what trend micro said to do. If anyone else knows about the virus id like to know.
