What is Windows Accelerator Pro?

The Malwarebytes research team has determined that Windows Accelerator Pro is a fake anti-malware application. These so-called "rogues" use intentional false positives to convince users that their systems have been compromised. Then they try to sell you their software, claiming it will remove these threats. In extreme cases the false threats are actually the very trojans that advertise or even directly install the rogue. You are strongly advised to follow our removal instructions below.

Choose the Kaspersky Rescue Disc, Graphic Mode in the first screen.
Once the program is ready to be used, make sure to get the latest updates.

When this is done you can start the scanning procedure. Scanning for Hidden Startups is sufficient.
The results of the scan will be show in a popup window like this one.

After having removed the ransomware you can use the Rescue Disc menu to reboot the computer.

Check if the procedure was successful and don't forget to reset the boot order settings to what they were.
