This is a virus problem.

1) First use cCleaner to cleanup your system
2) Boot in safe mode, and do full system scan using one good updated antivurs, and two good updated antispywares.

3) If possible, boot in safe mode with networking, and do full system online scan.

4) After you have done full scan, and system cleanup.
start -->> run -->> type
sfc /scannow

Insert windows XP CD when promoted -> restart when promoted

I hope this should solve the problem.
