Dear Mary, My understanding of the way anti-virus programs work is that one can only have one of them installed at any one time. Trying to install two, even if only one will be used at a time, will create serious conflicts. Recommend you don't even try it! As a long time user of AVG I can recommend it - it's very easy to use, runs quietly and efficiently, and is, of course, free (for a single user and non-commercial use). It seems to be very thorough indeed. I moved to AVG some years ago when my paid-for Norton's upgrade refused to work properly, and have never regretted the change. By the way, the free version of AVG is not readily available on the regular AVG site - what is free there is 30-day trial of their paid-for version, which has a few more features - AVG has a separate site for the truly free version, and the link is http://free.grisoft.com/ww.download-avg-anti-virus-free-edition Good luck - = Cheeta [log in to unmask] At 10:09 AM 5/10/2008, Camerons wrote: >Thanks for the suggestions.
