New viruses may sometimes go unseen by AV scanners. Mytob & Bagle varieties are examples of such. That is why a lot of AV products add ProActive protection. NOD32 according to a test on www.aw-comparatives.org/ scored 70%. It scans files on code, and urges suspect files to unmask in a safe box on the machine: virtual PC. So the vulnerability window only stays ajar and the risk of infection is less. What are the capabilities of AVAST in heuristics?
Users should consider not browsing with administrative privileges, this will also limit the effest of these first day virus infections as they aren’t able to reap so much havoc without admin privileges.
For ease of use I would suggest that you create a folder called DMR (on the C:\ drive) rather than the default location burried in the documents and settings folder. This makes the path in your shortcut much shorter, but this is your choice.
For each program (browser, email program, etc.) that you want to run with restricted rights you need to create an alternative desktop shortcut to launch it via DropMyRights.exe.
The target location in the alternative shortcut would look something like this - C:\DMR\DropMyRights.exe “C:\Program Files\Mozilla Firefox\firefox.exe”. What this is doing is calling the DropMyRights.exe, which launches the program with restricted rights.
You will need to change the icon as it will look like a plain old MS DOS icon, rather than the original programs icon.
