If you have downloaded the most recent MSRT from Microsoft (from the monthly 'Cycle Update'):
Right click the desktop > New> Shortcut; then type in " MSRT " (sans quote), a shortcut will be made directly to run the tool.
This will identify known malware, and corrective action taken.
Has full UI; quick scan takes 5 minutes; full scan is much longer.
Gives results of scans, checks e-mail, etc.
Very handy set-up.
