My best guess is that Iolo never installed correctly to start with and the way in which it has been removed since has only added to the complications. This is yet another of these odd-ball security apps which causes problems for a lot of people when they try to remove it.

I'm assuming that now you may well have system conflicts, especially within the registry, which will be very difficult to locate and fix. Although I no longer service PC's when I did, and whenever I encountered a similar situation by far the best solution was a reformat. You could hire a tech to look at this for you but there would be no guaranteeing a clean result. Unfortunately, in this case file and registry cleaning software won't help either.
