PE Guard is a free tool that protects your computer from any virus or malicious programs. It does so by preventing:
- A virus / program trying to copy itself to your system. (PowerGuard Mode)
- A virus / program trying to inject itself into one of your PE(Portable Executeable) files.
- Any rootkit / program trying to write a new Driver(.sys) file in your system. (PowerGuard Mode)
Once installed, click Next when the First run wizard dialog box appears. Once the wizard is complete, hit Finish.

This program has no GUI(Graphics User Interface) and works directly from the system tray.

When the program finds a PE file is being written it prompts through a dialog
When you check any box
Apply to this pair always box makes a rule and the PE file will be ALLOWED,REVOKED WRITE ACCESS,PREVENTED ANY ACCESS with the process
Apply to this process always box makes a rule and the process will always be ALLOWED,REVOKED WRITE ACCESS,PREVENTED ANY ACCESS
There are two modes, Power GUARD and Normal GUARD. It is recommended that you let it run in Power GUARD mode for maximum security.
Now lets talk about it’s daily life usage. You insert a virus infected USB flash drive and viruses such as autorun virus and others try to copy themselves to the computer. Once the virus infects your computer they try to inject themselves into as many executable files as possible.
This program makes sure both actions taken by the virus are stopped immediately. In other words you can say that this program provides first line of defense against viruses.
