PestPatrol is a powerful security and personal privacy tool that detects and eliminates destructive pests such as Trojans, spyware, adware, and hacker tools. It complements your antivirus and firewall software, extending your protection against malicious nonviral software that can evade your existing security and invade your personal privacy. PestPatrol defeats the threat by detecting and removing spyware and adware that uploads information about you, your computer, and your surfing habits; remote access Trojans (RATs) that allow an attacker to remotely control your computer; keystroke loggers that can steal passwords and other confidential data; denial-of-service attack agents that can crash or hang a program or your entire system; and probe tools that look for vulnerabilities on your system that a hacker can exploit.
