There are ads on US television from "MyCleanPC.com" offering to scan your PC and show you any problems.... then for a price, they will sell you their "fixit" program.

But...if you Google it, you'll discover that they ALWAYS find problems. Tests have been done with clean, never used PCs... and they find hundreds of malware, viruses...etc.

Total scam and ought to be investigated....

Use ONLY vetted and approved programs to safeguard your machine.
