Ok here is the situation. I wanted to be like the big boys,who have a back up AV to use as a scanner. Well I tried. I downloaded KAV Lite and set it up to not load at start up. The monitor didn't run. Well I was having problems with the system locking up when I did certain things. I removed KAV and now I think everything is normal. I know a lot of people have two or more AV's and don't have problems. A lot of people told me to get F-Prot for DOS. Well I have NOD Ver 2 so I figured how about NOD for DOS. Can anyone tell me how, first download,store it on the computer,and then use it. Also does it get updated and if it does how do I deal with the updates? Thanks for the help.
