This group calls me every week, sometimes three times a day claiming they can see malicious activity and viruses on my computer (when I do mange to talk to someone).  The claim they work in support of Microsoft.  

Most of the time the phone just goes dead after 5 seconds.  There are different callers, all with a middle-east accent.  The phone number most often shows up as just 510005, but also shows up as 213 651-0005 or 210 251-0005.

I ask to be taken off their list but they keep calling every week.  Don't listen to these jerks.  It is some kind of scam.

The 51005 number has been calling me claiming to be a pharmaceutical company, but everything else you said has been the same experience with me as well.  I want to block them.  How did they get my number??

They called identifying themselves as 'the service department for my computer' telling me that my computer had become infected with viruses, spyware and malware and that they were going to help me correct the problem.  When I told them I had a Mac and didn't think my computer was prone to those sorts of things, they hung up.
