Microsoft is a worldwide company, and they don’t have a tech-support hotline. It would cost a lot of money to reach them in that way. It’s the reason why the official company avoids the service and the scammers who mask themselves as Microsoft love it.

*Your Windows (Microsoft) Computer has been blocked*

Windows System Alert!!

Call Microsoft At 1-888-243-3533 !

You have been blocked from accessing the Internet.

Your e-mail passwords and other account passwords

Your Facebook ,skype,AIM,ICQ and other chat logs
Your private & family photos and other sensitive files

Your webcam could be accessed remotely by stalkers

How Infections with The Your Computer Has Been Blocked Scams Are Distributed

Several methods have been used by hackers to initiate the malware infections. Most of the installations occur through software bundles downloaded from the Internet. Computer users typically download “free” or “trial” versions of popular products from untrusted sites or P2P networks. Many of these files are actually infected files or even counterfeit programs that might imitate the real software packages. Depending on the case the user might not be able to actually install a piece of software or get a trial version. In either case, the malware has already infected the computer as it has been bundled with the program, installer or both.

Malvertising is the other primary distribution method of such malware threats. Malicious ads are often served on hacked sites or spam networks that the criminal users operate. Browser Hijackers and various adware toolbars are also responsible for a significant number of infections.
