I am not certain if I will be able to offer any conclusive close to this report ‘blog’ but I am wondering if perhaps the order and timing in which Avast & Comodo updates were installed on these 2 computers might have something to do with this problem. I am at the moment suspecting the possibility that the updates were installed at almost precisely the same moment, causing some installation details to cross paths in the process.

Unfortunately I can never get direct access to my friend’s computer to service it when needed (he can get rather busy) so it might be a moment before I can uninstall components and test this theory.

On my end I am feeling very good about the latest updates on both Avast & Comodo (I have also seen them working extremely well on other systems). These updates did seem to arrive at precisely the same time… This set up a situation in which they were both much more likely to be installed at the same moment. I think that both software designers seem to be offering some very good product at this time.

Thanks to all for comments & I may be back if I learn more, but I doubt that I could prove my conclusion in any case. It just happens to make a lot of sense to me.
