Check this out: http://www.gfi.com/lansim/lansimfeatures.htm It monitors system files and user defined files with MD5 Checksum and it is freeware.
This makes scheduled scans of the whole drive for changes, there's no kind of warning when you run anything. Also, it's main purpose is to keep tabs of what files on ANOTHER computer have changed, ie in a workplace. When something changes, it fires off an email, rather than giving any kind of alert to the user of the computer. This is a very different type of product geared towards businesses rather than home users.
I know, but it is a good thing for some peope to have. And you can define what you want it to scan and it can work on a local computer. I just thought it was interesting and wanted to post about it.
Hi Ajohn, As Notok has stated it is of no relevance to Process Guard. I will close this thread now but please do post your link etc. in the Software & Services forum if you wish to to discuss the GFI software further. Thanks. Pilli
