Windows Cleaning Toolkit is a rogue anti-spyware program from the
family of computer infections. This program is considered scareware because it does not allow you to access your Windows desktop, terminates legitimate applications when you attempt to run them, and display false scan results and security alerts that state your computer is under attack. This program will also be configured to start automatically before your Windows desktop is shown, which makes your computer unusable until the infection is removed. Windows Cleaning Toolkit is distributed through web sites that display a fake online virus scanner that states your computer is infected and then prompts you to download the installation file. This infection is also promoted by hacked web sites that contain exploit code that tries to install the infection on your computer without your permission or knowledge.
Once Windows Cleaning Toolkit is installed it will be configured to automatically start when you login to Windows. Once started, it will pretend to scan your computer and then states that there are numerous infections present. If you attempt to remove any of these supposed infections, the program will state that you first need to purchase a license before being allowed to do so. As all of the scan results are false, please ignore any prompts to purchase the program.

To protect itself from being removed, Windows Cleaning Toolkit will also block you from running any legitimate application on your computer. It does this to prevent you from running legitimate security software that may detect it as an infection and remove it. The message that you will see when you attempt to run a program is:
Firewall has blocked a program from accessing the Internet
is suspected to have infected your PC.
This type of virus intercepts entered data and transmits them
to a remote server.
When you see this message please ignore it as your programs are not infected and will work normally after this infection is removed.
While Windows Cleaning Toolkit is running it will also display fake security alerts that are designed to make you think your computer has a severe security problem. Some of these warnings include:
Trojan activity detected. System data security is at risk.
It is recommended to activate protection and run a full system scan.
Recommended: Please use secure encrypted protocol for torrent links.
Torrent link detected!
Receiving this notification means that you have violated:
- the copyright laws. Using Torrent for downloading movies and licensed software shall be prosecuted and you may be sued for cybercrime and break of law under the SOPA legislation.
Just like the scan results, these warnings are fake and can be ignored.
Without a doubt, this program was designed for one reason; to scare you into purchasing the program. It goes without
saying that you should definitely not purchase Windows Cleaning Toolkit, and if you already have,
please contact your credit card company and dispute the charges stating that
the program is a scam and a computer virus. To remove Windows Cleaning Toolkit and other
