Malware, spyware, and other junk software makes it onto your computer for a number of reasons:
- You installed something you really shouldn’t have, from an untrustworthy source. Often these include screensavers, toolbars, or torrents that you didn’t scan for viruses.
- You didn’t pay attention when installing a “reputable” application that bundles “optional” crapware.
- You’ve already managed to get yourself infected, and the malware installs even more malware.
- You aren’t using a quality Anti-Virus or Anti-Spyware application.
