What is System Care?

System Care Antivirus is a fake antivirus program, which aims to deceive PC users into purchasing a useless license key. This malicious software imitates legitimate security programs and attempts to encourage unsuspecting computer users into making the purchase.

To achieve this deceptive goal, System Care Antivirus performs fake computer security check-ups and mimics the detection of various high-risk malware and virus infections. Furthermore, this rogue program generates false security warning pop-ups.

This bogus program often installs on users' operating systems via any security vulnerabilities detected, and after infiltration, makes certain registry modifications, blocks execution of installed software, disables the Task Manager, and hijacks Internet browsers.

The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.
