I have McAfee anti-virus protection on my computer.  What I was wondering is if there is any other anti-virus that I could put on my pc along with McAfee that is known to be compatiable?

NO.  never, ever, ever install more than one antivirus at once, they tend to not be compatible with each other and often will completely crash your computer.

My wife installed mcafee overtop of Trend PCCillin at her work, and it took me an hour and a half to fix it.  It was a nightmare.

don't do it...  seriously.

If you're worried about protection, make sure you ALWAYS update your virus definition files as often as possible.  And don't open attachments from people you don't know.

Basically each one would find the other one as a virus

Not necessarily.  My wifes machine seemed to install fine, then when it rebooted (as it said it had to) it wouldn't boot into anything but safe mode.  Screwed up the registry majorly.

eventually-probably, different companies release their updates at different times and respond to things in different priority

Some of the vendors offer an free online scan (doesn't fix anything) that you can use to double check your software

Beef's right tho, two AV installations are a recipe for a headache

I have run two anti-virus programs for two to three years now.
Orginally I had Fix It Utilities that contained the Anti-Virus Program from Trend Micro and the Free InnotuclateIt PE from
Computer Associates ETrust.  they offered a deal on the EZ Amour package that contained EZ Antivirus which I installed and used in conjuction with the Trend Micro that came from Fix it.
Subsequently I upgraded to Systems Suite 4 and then 5 which
had the Trend Micros anti virus and the two continued to run
together without difficulty until Computer Assoicates cames out with its version 6 which was incompatible and my system froze.
So I just uninstalled it and went back to 5.4.3 I think until the
renewal time and since I had paid for the entire EZ Amour Package for two years this September and only used the EZ Anti-virus I wanted to just renew it for $9.95 , but they would let me do that and said I had to renew the entire package.  So I just
uninstalled it and installed the Free AVG from Grisoft and it and
the Trend Micro in my System Suite Package have no problems
existing to gether.  So If you wanted to try to run two, I would
suggest trying one of the free Anti-Virus Programs that are available, keeping in mind that usually two anti virus programs
running currently will conflict.

Here are some of the free one:

Bronson Elliot--- who helps produce the LangaList Archives for us--- sent in a couple interesting items:
Fred: I received today's edition of the AnchorDesk from David Coursey with the following article for an offer to download a full version of Panda anti-virus for free,10738,2914249,00.html
I've never used Panda before but I couldn't pass up this offer.-- Bronson
Panda has a good reputation, but I've shied away from recommending it as a free AV tool because the qualification form was quite restrictive. But according to Coursey, the Panda people don't mind if you, um, fudge your answers a bit on the forms to qualify for the free download. As far as I can tell, it's true: Panda has a new PR team, and they seem intent on getting better visibility for Panda. Seems worth a look!

Regardless of LRI41's amazing success somehow running two AV's at once (older products, no doubt) I must still recommend, very strongly, against trying to do this under any circumstances unless you want a very annoying and complicated process to fix whatever messes up.

: notapcpro,  Please note that I am not suggesting at all that
you attempt to run two anti-virus programs at all, all I am saying
is that it can be done under certain circumstances, but as you see above and/or read on any other Boards on the Web, most users "in the know"
recommend against it.
