PUP.Speed Cleaner Description:

PUP.Speed Cleaner is another PUP (as known as potentially unwanted program) found by Malwarebytes Anti-Malware recently. Technically speaking, PUP doesn’t belong to a virus because it can neither spread nor replicate itself. Therefore, it can escape from the detection of many advanced anti-malware programs. However, this kind of threat can perform a lot of harmful activities on a target machine once it is downloaded. The most obvious symptom you can see after your computer is attacked is unstoppable commercial ads and misleading information which will pop up on your browser whenever you go online. Now Internet Explorer, Google Chrome, Mozilla Firefox and Apple Safari are the main targets of this malware. It is urgent to remove PUP.Speed Cleaner once upon detection.
Getting a potentially unwanted program installed is a frustrating matter because it is hard to be uninstalled. Users cannot uninstall PUP.Speed Cleaner by using the same way they uninstall other legitimate programs because this threat will not even show in Control Panel/Add or Remove Program. It hides in the root of your system and does everything it can to interrupt your browsing experience and even damage your computer system. It is very important to know the way it comes to your computer because no one would like to get such an annoying thing on their computer. As similar as a browser hijacking threat, it usually gets installed on your computer by bundling itself to programs, music or flash player etc. which you downloaded from the Internet. Computer users should be cautious when they are about to download things on the Internet. If you detect any symptoms listed below, please clean up the computer as soon as possible.
