Before running extensive maintenance and scanning for viruses, malware, spyware, trojans and other culprits, I always recommend backing up your data. Just in case. So proceed only if you’re comfortable that you’ve backed up your stuff.
Use this process in this order:
1. run OS updates and video card updates (restarts may be required – do all updates before proceeding)
2. run web browser updates (usually does it automatically but sometimes manual intervention is needed)
3. run Ccleaner’s “Cleaner” tool (analyze first, then clean up)
4. run Ccleaner’s “Registry” tool (backup registry items at promt, then run)
5. run Microsoft Security Essentials (remove quarantined items)
Usually steps 1 through 5 is enough. But if you suspect more issues, then proceed in the following order until:
6. run Malwarebytes (go to quarantine and remove those tagged as “adware”. PUPs stands for Potentiallly Unwanted Programs, so don’t remove those as you might be deleting programs you know aren’t a threat.)
7. run Housecall (remove quarantined items)
8. run TDSSKiller (can’t remember if items get moved to quarantine, if so, remove items also)
9. run Ccleaner again – last run (first run Cleaner than run Registry – opt to back up registry before fixing issues)
