If you believe your PC infected with viruses...you can download a FREE virus scan program...
On two occasions i have received a phone call from two individuals of a Hindu accent telling me that there is a virus on my computer system. I pretended i was interested and so I went along with the latter individual who gave me a weird name I could not understand. He directed me to goggle and then asked me to go to the search bar and type in "teamviewer". He said he would help me with the virus in my computer, a mac mind you. When I asked him how he got my telephone number he said that he worked for Microsoft and that that department is not aware of this type of info that another department was. The day before i received another call from the same so called Microsoft company at which time i simply hung up but these people have my cell number and home phone number and its quite alarming on how they got it and are really trying ton hack into my computer. i just think it is fishy and I may be wrong but my gut feeling is telling me watch out and so now im telling you.
Thanks for posting this warning. We just received a call from that number today (Oct 12) here in Montreal, Canada. We did not answer it. This scam has been around for a while apparently: http://www.sevenforums.com/system-security/98111-teamviewer-scam-beware.html
