I hired a company to clean any viruses from my PC.
Exactly how did you um... hire a company
to do that? You didn't perchance just click on a random banner ad from the internet did you?
Because it's likely you were duped into some scheme that put more crap on your computer (spyware, malware, spamware, crapware, whateverware, etc...) from the very sketchy/skeezy company you arbitrarily hired without finding out whether it was a legitimate and honorable service or not.
