I'm using Prevx 184.108.40.206 in evaluation mode (free version) with safe online disabled. OS Vista 64 HP. If I try to copy my Firefox user folder somewhere to make a backup, Vista displays a window that continuously asks for permission (admin rights). The copy fails because -it says- I don't have rights to write on the destination folder (it doesn't matter which one: I tried on the same folder, on the desktop, on another hard disk and partition, always same result). The issue occurs only with two (very critical for security) files: signons.sqlite signons3.txt So, Why am I writing all these things here? Because if I temporary disable Prevx, I can do the copy without any issue. I wonder why Prevx seems to block my copy. The free version should not do anything at all except monitor the situation, I think. Note that I don't have any alarm or message from Prevx when I have that issue.
