I was using McAfee for several years as part of their Office2000........ I still use a few, mostly WinZip and Fortress, the encryption utility. But there's nothing there I can't live without or easily replace with something else.
Exactly. I would dump the whole package. Some "power utility" programs wrap themselves around the guts of your system real good. There are many freeware programs to replace them that are better!
I once started to set up AVG, but stopped when the setup package told me I needed to download some enormous file from Microsoft
I do not know of any "enormous file" that AVG requires from Microsoft. Hopefully we will get Avast up and running for you.
As to the ISP, the phone number is exactly the problem. I have yet to find a second company that has a local access number for my little neck of the woods
Let me have your area code and I will see what I can come up with.
Ok, I sent you a rather long IM to conserve space here as to recommended steps and programs that you might need.
To fix things, you need tools and that is what I sent you.
Basically (for information to other users), you should completely clean out your hard drive and check it for errors. The registry is probably a mess by now so it will need a polishing. Finally, complete removal of any trace of Avast, AVG and McAfee, followed by an online virus scan.
Optional programs might be
Smart Uninstaller which does a much better job than Windows at taking out programs without leaving junk behind, and
Clean Ram which always adjusts the available RAM to keep the computer running at its' best.
Does this guarantee to solve the problem? Well, if it doesn't fix it, then either try another AV or reformat the HD and start over from scratch.
Good luck
