My browser was constantly being hijacked. Eventually it froze with a flashing pop up "from google" saying it had a virus and to call omnitech. I called. They told me that I had a polymorphic virus disguised as Windows and hackers had access to all my private information so severe that I could use another computer, log into anything and that computer would remember all my personal info, as well as download a virus. Would cost me over $300 for the fix(lie). I paid and gave them access. They downloaded a pop-up blocker, and several things that made my Antivirus software flip out, which they then disabled. Constant computer problems, 3 months in I found out what a polymorphic virus(they lied), found out they could not diagnose that over the phone(lied), found out they had a one time fix fee for $90, (lied). Demanded a refund because they lied to me to get my business, we settled on refund for the service I hadn't received yet. They refunded my money. Sold the computer to a friend, watched them format it completely. 2 years later I'm STILL getting calls 2-3X a week from omnitech, omnitech claiming to be Google, omnitech claiming to be Microsoft. And people who won't tell me who they are. All from different numbers, including one guy who said I was a $#*!ing liar and hung up on me because I told him the person I sold it to formatted it. For the first year I just repeatedly told them I was no longer a customer, was disgruntled and to please stop calling. The harassment and sudden aggression of these people has got so bad Now I can't answer my phone at all. I screen every call I have, and yes, they've even hijacked numbers and called me from numbers I know.
