Some clown from this number, 521-589-0000 call 4 times in the last hour. When I finally answered it I found an Indo soundly male telling me I had bugs in my computer and that he was from Microsoft, and under orders to help me fix the problem.
I called him full of IT, and told him not to call back, or there would be consequences.
    He called straight back, and spoke to my wife, referring to her as a &%#$ing Bi***, etc........
    Why aren't freaks like this caught and dealt with by Law Enforcement? These people don't deserve to breathe the same air the rest of us do.

I received a call from 15215890000, it was not very pleasant. The guy on the phone claimed my computer was ready to crash and he was going on about how it was malicious...? I informed him that my computer has not even been plugged in for the last little while. He just continued telling me the same thing over and over so I got fed up and hung up. He called back immediately, I answered and said Stop calling here! And hung up. He called back again right away, I answered Hello? And he said, and I quote "You f****ng prostitute! Why the f*** did you hang up?!?" And he was yelling and sounded very angry. If I receive one more phone call of this manner I will have the police involved!

I received a call from phone # 1-521-589-0000 The gentleman was trying to get me to go to my computer, claiming it was going to crash. I informed him that my computer has not even been plugged in for a while. He then continued rambling on about my computer having something malicious and was going to crash.

Got a call from this guy just now. Said he was from microsoft and that my computer was registered to a number. I asked him what name was registered and he gave me the name which the phone number is under, not the name of who lives here. I told him there was no such person here. He said he was going by the number, I asked for the number and he hung up. About five minutes in all, the guy was getting pretty excited in trying to sound convincing. I am annoyed that I pay for my phone and get stupid calls like this from other countries trying to rip off North Americans. I hope no one falls for this. I am sure they are trying to get info from your computer to rip you off.

This guy tried the computer maintenance scam where something is supposedly wrong with you computer, and said it was for my lap top or computer. Do not give them any info!

We just got a phone call, they told us they got a signal that something was wrong with our computer, what a joke do they realy think that we are so stupid!!!!

Just got a very aggressive call from this number. telling me i have a virus on my windows computer. after about 10min of saying the worst bullsh*t i've heard in a while, i let him know that i study in computers and shot some information his way that he probably didn't even understand. he then said "ok no virus good bye" and hung up.
This is for sure a scam, seemed to be calling from a cell phone with bad reception and sounded as if they were outside.
I think they were going to ask me to go on my computer and give them my IP address or something and then steal banking information or something... anyways, if anyone gets this call, please hang up and if you're actually worried about computer problems, call a real company and let them check your stuff out!

Just received a call from these guys a few minutes ago.  They claimed to be from Microsoft, and wanted to help me fix my 'windows' computer that was having problems.  I told him there were about a dozen such computers here, and asked him to identify which one he was talking about.  He said they supported XP, W7, W8, but did not know the ip address or MAC address of the 'problem' computer, so I offered to transfer the call to Tech Support.  I pressed a couple of buttons on the phone than changed my voice slightly, and pretended to answer "IT Department".  The clown promptly hung up.  :)

Called when I was out ... no message. I seen this before.

Call comes from Hong Kong

Where do these a-holes get my number from?   Data-protection is a joke!

8:20pm ET.  When I said hello child on other end said f*** you.  

Obviously just another telemarketer with his work phone in his house, dialing numbers for his kids, or letting his kids play with his work line.

Not as good as the one I got from the telemarketer who insisted in telling me that I had a windows problem, all the while his chickens were clucking in the background.

I get a call from this number about once a month. At first there is just dead air and static and then there is a goodbye. Around here we call it the goodbye call.

Got a weird call from this number too. Very aggressive, very brief. Seems to be selling something.

Where does this call emanated from
