Although it would sure be helpful if you could tell us more about your computer, (operating system, make and model, antivirus you're current using), please download, install, update, then run a full system scan with BOTH tools after restarting in Safe Mode.. Delete anything the tools find in Safe Mode, then restart into "normal" Windows and run full system scans again.. After deleting anything found during each scan, restart the computer. Run the scans till nothing shows up after a restart to normal Windows.
