Spyware

MalwareScanner, or Malware Scanner, is a rogue anti-spyware application designed to scare you into purchasing MalwareScanner's full version. MalwareScanner is usually downloaded and installed manually. Once installed, MalwareScanner will run a scan of your computer and generate exaggerated spyware threats which are usually false positives. When the scan is complete, the 'scan results' window appears which shows how many spyware threats your computer allegedly has. This tactic is an attempt to trick you into purchasing MalwareScanner's commercial version. In addition, MalwareScanner may generate annoying popup advertisements that may cause unstable system performance.
