877-753-6941

keep getting calls from these people ,supposed to be with windows service center and we supposedly have some sort of computer blockage !!

Message came on my computer saying "Your computer has been blocked.  Please all immediately 877-753-6941".
Jerks aren't getting my money!

However, they seem to have put a virus or some other something in my computer as their page keep popping up and my puter freezes.  The page says it is the "Microsoft Official Support System".  Anyone have any suggestions?

Reboot the computer. Most of these popups are just clever javascript programs.
Run your antimalware / antivirus program.
You can take it to a brick-and-mortar computer repair facility in your local area for help too.

Exact message just popped up on my computer! Thank you for posting. This stuff is scary!

I just got the same message, called number and they wanted me to allow access to my PC, I hung up and rebooted, will keep an eye out for anything strange.

Same as all the others.  Popup window saying I had a problem and need to call this number immediately.  Tried it for the hell of it and they requested remote access.  Hung up on them.  Rebooted and all seems fine.  Looks to be a recent scam.  7 or 8 of us in less than 2 weeks have made their way to this site alone to report.

Definitely a scam - even with up to date protection software, and not clicking on any suspicious attachments, I got the screen and screen lock.  If you have good spyware, use taskmanager to close that browser, then delete all browsing history files, then run a full scan just in case.  If you dont have protection software, Google that phone number, you will find ways to remove it from your PC.
