You certainly haven't provided much information. However, it would seem
that your computer is not virus/malware-free. Run either Sysclean
(first link below) or Dave Lipman's Multi-AV (second link below).

After you've done your initial scan with whatever first-line av tool you
choose, update your full-featured antivirus (or if you don't have one
get one) and do a thorough scan with it in Safe Mode. Then continue
your cleaning by going through non-viral malware removal steps per the
first link above.
