Called at 11:56 AM saying (in a heavily accented voice) that his name was "Shawn Williams" and claiming that my computer was having problems. I hung up.

Received a call from this number at 12:02 p.m. on October 1, 2013, which I answered as it appeared to be a local caller.  Only 'dead air' for several seconds until an automated voice said "Good Bye."
Checked the number and found this site.  I don't know who the caller was, but I will now block the number.

Got call 6pm on Oct 2.  Heavy accent (Indian) voice claiming to be from government and telling me my computer had been hacked.  Enjoying fantasy, I asked him how he knew.  He attempted some weak explanation and said if I gave him some security reference he could help me fix it. I got bored and hung up.

Got a call on Oct-08 at 7:45 pm, said that the call from some company (not heard it clearly) on behalf of Canada Protection Agency, that my computer was hacked by some third party and they were asking money on behalf of my name. But as his voice was not clear, I ask them about their phone no to call back, he gave me the no, 323-647-4977 and his name is Shawn William. when I searched for this no on internet, shows that, it's belongs to Los Angeles.

Got a call on October 9 at 7:59 p.m.  Caller was a male, indian accent.  He demanded to speak with me.  He knew my full name and previous address.  Kind of spooky!  I asked for his name, after a hard time he said he was "Shawn Williams".  He was very rude and kept asking to speak with me...I denied that I was the person he was looking for and he asked for my name.  I asked him why he'd want my name and he said I had a nice voice.  I then told him that this must be a crank call and hung up.
