WINPROSCAN.COM SENDS A VIRUS TO COMPUTER THAT INHIBITS ALL YOUR SECURITY DEVICES AND FORCES YOU TO USE THEIRS TO SOLVE PROBLEM. BAKU, Arizona

Some other people have written the same complaint.  A virus pops up and blocks you from getting to any website including your own security system (i.e. McAffee) and forces you to use their product to get rid of the virus.
There is nothing you can do except to use their product and by that time it is too late because they never send your the software.  My advice is to shut the computer down and bring it to a professional computer service for advice and repair of the virus.  I am trying to cancel this order working with my credit card company to deny payment to these thieves.
