Cyber Sitter (aka CyberSitter version 10.0) is yet another rogue program. CyberSitter employs trojans to infiltrate computers without user’s permission. It reports nonexistent threats in order to gain a purchase. The worst thing about this malware is its fake scanner. Cyber Sitter warns people about malicious files and then urges them to buy a full version of this program. Some people may trust Cyber Sitter enough to delete the infections manually and damage a computer this way because CyberSitter indicates system files being dangerous. Do not purchase Cyber Sitter! It is not a security suite; CyberSitter is dangerous malware. The full version of this program doesn’t even exist; it’s just a lure to gain money. Remove Cyber Sitter with no hesitation.
