What is Windows Accelerator Pro?

Windows Accelerator Pro is a rogue anti-virus program from the Rogue.FakeVimes family of computer infections. This program is classified as a rogue because it pretends to be an anti-virus program, but will instead displays bogus scan results, report non-existing computer infections, and does not allow you to run your normal applications.
In this case, not only is Windows Accelerator Pro going to disrupt your system, it’s going to try and trick you into making a purchase using your credit card.
Windows Accelerator Pro appears in the form of a fake Windows warning on your computer system that reads you have a specific number of viruses on your computer (usually in the hundreds) and that this software has detected those viruses. To get rid of them you must purchase the full-version of Windows Accelerator Pro. It’s important to remember that by purchasing the “claimed full version to remove the viruses” you will be submitting your personal information to unscrupulous persons and may also end up being a victim of credit card or identity fraud or theft.

To protect itself from being removed, Windows Accelerator Pro will also terminate any application you try to run on your computer. It does this to protect itself from being removed by legitimate security programs and to scare you into thinking your programs are infected. When this infection terminates a program it will display a message similar to the following:

Firewall has blocked a program from accessing the Internet
c:\windows\system32\taskmanger.exe
is suspected to have infected your PC.
This type of virus intercepts entered data and transmits them
to a remote server.

How did Windows Accelerator Pro virus got on my computer?

Windows Accelerator Pro is distributed through several means. Malicious websites, or legitimate websites that have been hacked, can infect your machine through exploit kits that use vulnerabilities on your computer to install this rogue antivirus without your permission.
Another method used to propagate Windows Accelerator Pro is spam email containing infected attachments or links to malicious websites. Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the Windows Accelerator Pro virus.
The threat may also be downloaded manually by tricking the user into thinking they are installing a useful piece of software, for instance a bogus update for Adobe Flash Player or another piece of software.
The Windows Accelerator Pro infection is also prevalent on peer-to-peer file sharing websites and is often packaged with pirated or illegally acquired software.
