Who called from 4086000586

They left no message. I called them back and a recording said "party you are calling in unavailable".

This company claimed I purchased computer repair from them, which I had not. They wanted me to connect online so they could show me malicious activity on my computer. I never purchased such a thing- beware!
Scammers~

yahoo acct hacked?

I got this call too. Referred to back when I paid $50 for a remote tech to work on my computer (which I had). This is why it kept my attention. They said I had been hacked and they could get rid of all the malware for a fee. When they said to pay by Western Union (because to pay by credit card the hackers would get my cc no's.) I knew it was a scam. Hoping they didn't install anything on my computer.

Received call from someone claiming to be from OmniTech who noticed problem when monitoring activity with my computer.  I have had OmniTech support in the past and had no reason to question the caller at this point.  I gave him permission to access my computer, he "ran some diagnostics" and determined that I had been hacked.  He claimed that the  hacker was on my computer at that time,  and that he could get rid of the hacker and all malware for a fee and extend my OmniTech service for 24 months for a fee of $349.99. I offered to give him my American Express number, but he refused saying that the hacker would then have access to my card number.  He then said I would need to send the money by Western Union.  Like a fool, I went to the local Western Union and at that point discovered that the caller was requesting that the money be sent to Thailand.  Obviously I did NOT send the money, and am on the phone with the real  OmniTech Support trying to ascertain if the hackers installed malware on my computer.  Lesson learned:  If tech support calls you, it is  more than likely a scam!  Call tech support WHEN YOU need them!!
