Run the free microsoft online safety scanner it will run antivirus

and antimalware scans,clean your registry, defrag your hard drive delete junk files, and you'll be suprised how well your system will run afterwards.

Run both of these on-line scans. Both are free and excellent at detecting and removing malware free of charge. There is no need to un-install your current protections before using these.

1. Scan for virus, worms, dialers, etc. and remove (free online scan, no downloaded program) with BitDefender's Online Scanner

2. Scan for trojans, adware, cookies, and spyware and remove (free online scan, no downloaded program) with Ewido Online Scanner ( now known as AVG Anti-Spyware). This is NOT the same as AVG Anti-Virus.

These scans will take quite a bit of time. The time is necessary to clean-up an infected computer.

Good luck.
