Eric, thanks!!! I have never gotten any bad advice in Comodo forums! When I get home I will do as you suggest and I'm sure any remaining problems will be resolved.
One more question if I may (and it may not belong in this thread). My neighbor starting letting me piggyback off his WiFi signal this past Monday, after I got tired of paying ATT a fortune for Internet. I have a nice D-Link card and pick up okay until I get an indoor antenna. Question is: Just by using the signal from his house, can I pick up a virus off his computer even if I never directly access the computer? And can he end up with a virus that I download and get from a zip file?
Sorry for asking, but I am very new to WiFi and don't really understand how that works. I can tear a computer apart and fix MBR viruses, but have no clue about signals.....go figure!

Hi kc,
The answer would be yes. What you are doing more than "piggy backing" on his internet connection. You are networking with his wireless router (which he also uses). As my wife likes to say about couples who get sick at the same time, "they are sharin' spit." I would set your CFP to the highest levels that still allow you to connect (yes, more alerts, but at least you will know what or who is trying to connect to your computer). If Avast failed you try another AV. Your neighbor may be a great guy, but might he become bored and curious one night, and start snooping the files on your computer? Under your circumstances I would take steps to make sure it is very difficult for him to get into your computer, and also to keep sensitive information stored "off site" (on a medium off your computer).
