I decided to install Process Guard Free on my system (Windows 2000 SP4 running F-Prot, NAV2002, Outpost, SSM, Tauscan, WindowBlinds, WindowFX, CursorXP, Synaptics touchpad drivers, Logitech mouse driver) and encountered a number of issues, a couple of which I would consider significant. First, the most serious problem: Execution Protection The prompt to allow/block a new process uses a separate desktop preventing access to any other tasks until it is answered. Unfortunately, with Execution Protection enabled, running as a non-admin user on my system would bring this prompt up without any mouse cursor (this happens with CursorXP running - disabling it avoids the problem). This makes it virtually impossible to reply to the prompt and since it can't be Alt-Tabbed out, powering off the system is the only way out. This prompt needs keyboard shortcuts - either standard Alt keys or a function key like SSM. The inability to access the normal desktop also blocks any attempt to use Windows Explorer to check the details of the file in question - I would suggest either including these (the information in the Properties/Version dialog specifically) or adding a "Details" button to provide this. Other issues... Procguard only runs under the Administrator user Running this as a non-administrator results in 5-second pause then the following message "Error: Please make sure Process Guard is installed correctly before continuing". It works normally when run as Administrator but would then allow anyone else using the PC to use it to access a command prompt window with Admin access. Human verification An excellent idea which many other programs should adopt, however it does make PG unusable for those visually-impaired users who rely on screen readers. Please consider offering an alternative option (a speech add-on that reads out the letters would seem a good choice). Procguard Interface Well... ick. I don't understand why some developers think the WinXP style of menus is so cool that it should be retro-fitted to Win2K systems. PG is not the only offender - but it does make it incompatible with utilities that change Windows' appearance globally (e.g. WindowBlinds) which is a pain. Please consider offering a "standard" UI as an option. Also, although the free version reports an error when selecting a colour scheme, shutting down and restarting Procguard brings it up in that chosen colour scheme. No big deal, but probably unintended. Program Checksums This could benefit from 2 features - adding a program (and the Allow/Block setting) manually plus the option to remove obsolete entries (programs that have been deleted). Overall, I appreciate that there are issues specific to my system and software configuration (and thanks for providing a free version to allow people to test this), but PG does seem to have some wrinkles I would like to see resolved before committing to a full version. I hope this helps.
