AT&T-Yahoo has an online protection package. It has Computer Associates antivirus on it. My father in-law had McAfee on his comp and accidently let it expire. I want to get over to his house and put AVG on it. Until I'm able to get to his house and do it, will the AT&T package be OK? I walked him thru the AT&T download by phone. I figured it would be better than nothing until I can install it. It has the AV, Anti-Spy, and the modem firewal is on. Does this sound OK?

It sounds fine to me....

Do not let it go too long with both antivirus running on his computer. More than one antivirus and\or firewall can lead to conflicts.

The ATT/Yahoo package is acceptable, but I always prefer to get my bread and my meat from different stores. Using independent applications that I have chosen makes me secure if I decide to change ISPs, and generally the individual applications are better because they specialise in but one area.

There is only one antivirus on it now, CA.

You might also consider installing some antispyware programs in addition to AVG when you install it - you could send your father in-law instructions to download spybot and adaware whilst he waits for you to install AVG to increase protection. Spybot includes tea timer which provides excellent real-time protection whilst AVG may not be installed.
I would also recommend you install spywareblaster:

Out of curiosity, does the AT&T & Yahoo package's CA AntiVirus expire even if you continue using AT&T as your Internet & Phone service provider? And, does the security package come with anything else? BellSouth seems to despise my house, so my parents and I are considering an alternative (maybe cable instead of our DSL or we might join "The Network" with Verizon).

The protection is Anti-spy(used manually), anti-virus, pop-up blocker, parental controls, and mail protection. I don't know for sure but I assume the AV is free as long as you have their service.
