Twice now while I have left my PC idle for an extended period of time OA free has had a pop-up informing me that msiexec.exe was attempting to create an API so that a program could autorun. The first time I think the PC was also connected to the net for an extended period of time. This time I am not so sure. Both times now I have hit block. Is this process trustable? It seems to be trusted in OA but could some other malicious software be using it to create the API? I just find it suspicious that it has popped up for no seeming reason. The only possibility is that it has something to do with the automatice updating of certain programs, but even so why would an API for a autorun(this is according to OA) need to be created. Any ideas? I just find it very spooky that this thing just pops-up for no seeming reason after the PC has been left idle for an extended period of time when it may have been connected to the net. Oh and for the record OA lists msiexec as a windows installer. What exactly is it supposed to install?
