Remove Du Speed Booster (Removal Instructions)

Du Speed Booster’s evil rip-off version threatens user privacy

Beware that there are two different versions of this system optimization spreading around and one of them cannot be called anything other than Du Speed Booster virus. Another version of the program that shares the same title is NOT a virus or malware. According to its developer, it’s a “mobile application for Android devices, providing anti-virus security features and optimizing performance by removing cached or junk files.” However, if you have recently downloaded a program that is called “Du Speed Booster for Windows PC”, you are dealing with a potentially unwanted program^[1] that can cause unwanted activities on your computer. This program has been labeled as a PUP and adware because the biggest problem, which is initiated by it, is constantly re-appearing pop-up ads. They have already been reported on Estonian^[2], Latvian^[3] and other security websites. If this questionable program, Du Speed Booster For Windows PC virus, enters your computer, you can start dealing with ads that report about missing updates, fake ads that offer you various prizes, ads informing sales and similar notifications. Beware that these alerts are fake and clicking them can lead you to the infiltration of malware. Other issues that are typically caused by this PUP right after making system modifications can lead PC users to slow downs, annoying system scanners and security alerts, etc. If you want to avoid them, you should remove Du Speed Booster from your computer. The easiest way to do that is with a help of reputable anti-spyware, such as Fortect Intego.
