You should be able to uninstall it either by clicking Start - Programs - All Programs - Prevx 3.0 - Uninstall Prevx, or if that isn't there either for some reason, run the commandline: "c:\program files\prevx\prevx.exe" /prop UNINSTALL=Y Let me know if you have any questions!
Prevx should be listed in applications (go there through Start), then run Uninstall Prevx. If using Vista/W7 don't forget to run the uninstaller as admin (right click on the file). Edited to avoid duplicate posts.
pegas Prevx wasn't listed in start programs either. Used the command line and that took care of it. Thanks
