@aceroinox,I get this phone call all the time. The best part is they
always tell me it's on my Microsoft Windows computer, but I don't run
Windows on any of my computers. When I start grilling them about what computer
and what the virus is they get very belligerent. Usually they call
me a few choice words before they hang up. It's pretty funny.
This is not the only "tech support" scam. There is a group from India
who purport to be from Microsoft and call to "inform" you that you have
a virus on your computer or that your anti-virus software is out-of-date. They
have hit my aging mother twice, convincing her to go to a certain web address,
where her computer has been compromised along with all her personal information.
They have called me twice as well. They get very indignant and repeatedly insist
they are legit when you reveal that you are onto their scam. My
advice: if someone calls offering tech support or to update your anti-virus
tools, hang up on them immediately--it's a scam!
