Received three calls in the space of a week from this phone number. Each time I answer the caller hangs up. Annoying!

They're still doing it with the same number. For me they called themselves esolving.com

recieved a call from them "Online PC Care" on 17/10/2011.
They tried to get me to make system adjustments on my computer

The call I just received came from a blocked number, but the story is the same. "On line PC care" -- but I stopped him immediately by informing him he was breaking the law by calling me (CRTC do-not-call list in Canada). The call was obviously from overseas; there was a strong echo and a delay. I caught the alleged company name but not his name; he had a marked Asian accent. He was extremely polite, some problem with my name and do-not-call, he will make sure I get no more calls. Bushwah, says I. They are not using the Canadian do-not-call list, which they don't have to do because they are outside Canada.Of course, had I been clairvoyant and seen this discussion first, I would have let him continue to see what he was after! Thanks to the knowledgeable people reporting these activities.

I had a similar call [in Adelaide] last Saturday.
This time the phone number he gave [Asian voice claiming to be from the Computer Maintenance Department] was (03) 9014 9898
I was suspicious anyway, but laughed at him when he tried to persuade me that although I thought I had bought a Mac it was running Microsoft.  I wonder what he would have asked me to do if I had continued

This is a scam to get remote access to your computer.  If they get it they will install spyware/malware to steal personal information like ba nk details, passwords, etc.  Neither Microsoft nor its partners would ever 'phone you.  It would be a breach of their privacy rules.  The people who 'phone know nothing about your computer.  They rely on scare tactics and lack of computer knowledge.  There is a warning on the Microsoft website about this scam.

world pc tech is a genuine company...the problems of my computer were solved ,and they do value their customers.Getting registered was great..Thanks,,,,,,

Caller had foreign accent. Very difficult to understand. Said his name was Jim Smith. He said he understood I was having problems accessing the internet and Microsoft had him contact me. I did not get a phone number or enter information he wanted me to do. I told him I would check on it and for him to call me back later.

Just had a phonecall from a "Global Computer Foundation" claiming I had malicious files and junk mail she could help me to get rid out yet when I answered the phone she asked "Do you have a computer?" strange, since she already knows my computer "has" malicious files inside it. She wouldn't tell me how she got my number or knowledge that my computer contained malicious content and getting annoyed, I hung up and decided to look this up online. It seems dodgy and I will not give them any of my time in future.
