For years and years Iâ€™ve been using the Freeware security Spybot search and destroy.
Although itâ€™s a free product, donâ€™t let that scare you. Spybot does a great job of staying up to date with the latest threats out there, protecting your computer from various spyware / malware and even has some great tools which allow you to change system parameters such as which apps start with windows etc..
All in all, itâ€™s pretty much the defacto standard out there by Security Guruâ€™s and works with almost all Windows Operating Systems. butâ€¦ to tell ya the honest truth, Windows 7 along with Windows Defender (yes Windows Defender) and Microsoft Security Essentials some may argue you actually donâ€™t need 3rd party security tools but, itâ€™s probably never a bad idea to hedge your bets and use more than 1 company to protect your systemâ€¦??? Agree? Disagree?? I guess thatâ€™s what the comments below are for. ;)
