How to Remove PC Security Guardian (Uninstall Guide)

PC Security Guardian is a fake anti-virus program that targets users via SEO poisoning attacks, fake online virus scanners and infected websites. It reports non-existent viruses and malicious software on your computer. PC Security Guardian occasionally displays rather convincing security alerts, telling you that viruses are found, e.g., Trojan-PSW.Win32.Dripper, Virus.BAT.Gray.705, etc. The point of all this is to scare you believing that the detected viruses and malware "threats" are real. While the rogue AV remains low risk infection, inexperienced users could be fooled into paying to remove the threats which do not even exist. There is no guarantee that your credit card information aren't going to be sold to other third parties. So, do not purchase this phony security software. And if you already bought it, please contact your credit card company and dispute the charges. To remove PC Security Guardian from your computer, please follow the steps in the removal guide below.



Upon installation, the rogue application adds itself to the list of applications that runs automatically when Windows starts. It then runs a fake system scan and gives false reports of threats on your computer. PC Security Guardian configures Internet Explorer to use a proxy over a LAN connection. It hijacks the default browser and displays search results from findgala.com. It also may also display the fake "Reported Attack Site!" warning while browsing the Internet.



If you click the "Removal all" threats button, it will take you to a web page where they can purchase a license for the rogue program: either a 6-months, 1-year, or lifetime license ($50-$90). If you need an activation key, you may use this one: U2FD-S2LA-H4KA-UEPB. It works so far.



They even have their own support center.



It's possible to manually remove PC Security Guardian (associated files are listed at the end of this page), however, it is advisable to use anti-malware software. Besides, the offending randomly named files are hidden and even have the "protected system file" attributes, so it might be rather difficult for some of you to find those files. If you have any questions or need assistance in removing PC Security Guardian, please let us know. Just leave a comment below. Good luck and be safe online!
