I agree with Peddant, but right now I am having three problems I am trying to sort out.
The first is that I have not been able to connect to the update server for two days. I used their online tech support, and they confirmed the problem was on their end. Now, while I am actually writing this post, a small window popped up titled "ZeroSpyware LE," with nothing in the window. When I hit the X to close it, a notice popped up asking if I wanted to interrupt the updates. I still see no activity; they obviously are having a problem.
The second is that some of the items I quarantined are disappearing from Quarantine. In reading the documentation, one can infer that the Quarantine is reviewed and compared to their online data base, and those items which are not confirmed as spyware are restored. I say inferred, because it is not specifically clear on this point in the documentation. If my inference is correct, then this reduces my concern regarding false positives (reference my initial post). I have contacted their online support three times to discuss this problem, but I have been disconnected all three times before I can get an answer. Peddant, I would appreciate your review of Quarantine in the online documentation and see what you think. If my inference is wrong, this program is history.
And last, a problem specific to my setup. There are two users on this machine, each with their own profile. I downloaded and installed in my profile, and I had to establish permissions in order to get it to work in the other user's profile, even though the other user has full administrative privileges. Now, although I set the program to start on boot, minimized in the system tray, it only accomplishes this in the profile which logs-on first. Second long-on must manually start the program, which then automatically minimizes in the system tray.
The update window is still sitting there as I complete this post.
