Well I do not get a warning message for a Virus or something related to something bad happening. I attached a screenshot of the message I get when I take Slimjet out of the exclusion list under "File system Shield". It is in Dutch, but it basically lets me know that I can not get access to that file ... or I do not have the right clearance level for the file. But I am the only one using this computer so I have an admin account, so that can not be the case?
After I added SlimJet to the exclusion list under "File system Shield" I could use Slimjet again. So despite the fact that I did not get a Virus/Malware warning or such, it seems to me that Avast still some how blocks Slimjet.exe from executing when I do not exclude the Slimjet folder? ( At least that is the conclusion I come to at the moment. )
