See if you can boot into Safe Mode; instructions for tapping F8 is below.
If you can, do a System restore to before the problem.
Start>All Programs> Accessories>System Tools>System Restore.
You can also do a SR as you are entering into Safe Mode.
But, I was curious whether you can get to it.
And below is also Anti-virus, and anti-Spyware and Anti-Malware Programs.
You can use Safe Mode with Networking to install, and update them before
scanning with them while there.
http://www.avast.com/eng/download-avast-home.html
Avast Anti-Virus is XP and Vista compatible (32bit and 64bit Versions),
FREE, auto-updating, and a low resources user of your computer.
And, only have 1(one) Anti-Virus installed / running on your computer at any
one time..
Conflicts may occur if you have more than 1(one).
http://www.spybot.info/en/index.html
Spybot Search & Destroy 1.6 is a very good, FREE Anti-Spyware Program.
Download, install, update, and immunize your System with it.
Then SCAN with it.
Update it, and scan your System once a fortnight.
http://www.malwarebytes.org/mbam.php
Malwarebytes is as the name says, a Malware Remover!
For the Free version scroll down their page to either download from
Download.com, or Major Geeks.com
Download, install, and update.
Important re: Safe Mode
If you happen to find a problem that you can’t uninstall / delete, reboot
the computer, and go into Safe Mode.
To get into Safe mode, tap F8 right at Power On / Startup, and use UP arrow
key to get to Safe Mode from list of options, then hit ENTER.
RESCAN your computer with your Anti-Virus, Malwarebytes and Spybot S & D
while in Safe Mode.
If unable to install above Programs in Normal Mode:
Sometimes Trojans, Viruses, Malware, etc stop you installing and/or updating
Programs to remove them.
If that happens, reboot into Safe Mode with Networking, and install, update
and scan from there.
