PC Defender. How to remove? (Uninstall guide)

removal by Gabriel E. Hall - -   Also known as PCDefender | Type: Rogue Antispyware

PC Defender (or PCDefender) is a fake spyware removal tool designed to gain the income by pushing PC users into paying for its “full” version. The program is known to be a successor of infamous PC Defender 2008 which has caused many troubles for the users worldwide, so there is no doubt that PCDefender MUST be avoided. However, you may have no awareness about this scam installed into your machine because Trojan horses are used for the infiltration.

When in the targeted computer, PC Defender starts seeking its dirty commercial goals. Its unregistered version creates fake registry entries and adds some corrupt files at first. Then, invasion is usually followed by triggering system tray notifications and other alerts telling about infections that are “detected” in the PC. Victims are usually suggested to scan their computers that additionally report multiple infections trying to make them scared. They are misleadingly informed that only the “licensed” version of PC Defender can fix everything.

In fact, the above mentioned PC Defender alerts and scanners are falsified and created not only to scare users but also to get them into paying for so called “full” version. In the same time the system may be absolutely clear of infections and the reported ones are usually the same created by PC Defender. The only parasite is this rogue, so if you take your PC security and privacy important, remove PC Defender with all of its files and registry entries ASAP.
