How to Remove Personal Shield Pro (Uninstall Guide)

Personal Shield Pro is a malicious application claiming to be an antivirus program. Most of the time computers are infected when users are presented with a fake security warning that seems to indicate that the computer is suddenly infected with viruses, spyware or other malicious software and they are asked to install free malware removal tool to remove viruses. Cyber criminals use other sophisticated methods to attempt to trick users into installing Personal Shield Pro — including spam emails and drive-by downloads when simply visiting an infected website is enough to become infected by this fake security program and other malware. Once installed, Personal Shield Pro pretends to scan your computer for viruses and displays fake security alerts to make you think that your computer is infected. Generally, false positives and fake security alerts are the primary method used to convince the user of the compromised computer to purchase the rogue product. What is more, this form of malware can significantly slow your computer's performance, change your background image and download additional malware onto your computer. If your computer does become infected, please follow the steps in the removal guide below to remove Personal Shield Pro malware from your computer.



When Personal Shield Pro is running, it blocks certain application on your computer, usually Task Manager, Registry editor, other system utilities and of course legitimate anti-malware software. It displays fake notification saying that the program is infected:

Application taskmgr.exe cannot be activated. Reason: suspected in virus activitiy and moved to quarantine. Please, activate your antivirus software to clean application.
Personal Shield Pro displays other fake security alerts like every on or two minutes. Thankfully, this fake AV can be removed rather easily. If you are good with computers, you can remove this fake security program manually. But if you are not that good with computers then I suggest using free anti-malware tools listed below.
