EXE Vaccine protects your PC by acting as an executable file filter. It attaches to the operating system and filters all executable files, be it .exe .com .dll .drv .sys .dpl etc from all drives and all network shares against a list of files or paths, you, the administrator provide as trusted applications. If a prohibited executable (one not in the allow list or one explicitly defined in the deny list) is loaded, a customizable popup box informs the user with an intelligent message.

EXE Vaccine has been designed for ease of use. Out of the box, a control panel applet is installed which allows for the configuration to be quickly modified. By default the program files and winnt/windows directories are added which in many cases is all that is required to make a secured, yet functional system.

EXE Vaccine protects your PC all the time regardless of what user is logged in. To install software, or run executables from un-trusted locations, the administrator can utilize the control panel to stop the driver and briefly interrupt filtering while the software is installed. Exe Vaccine also protects tasks running in the SYSTEM account.
