When installing new software I am usually told to close all other programs. Do I really need to close my firewall and AV programs? I have gone back on-line a couple of times having forgotten to reopen them.
Virus checker and Firewall need only be ON if you are actually on line all the time [Broadband!]
If you are not on line you wont be zapped. It is a good idea to shut down all operations whilst software in installing, other wise there is the potential for a conflict ,as installing files try to enter registers that are active. There is a program =freeware I think called EndIt All- this turns off everything in one hit. Try a Web search for it. J
I'm with jack on this one. I always close everything & after installing restart my PC (even if it doesn't prompt to do so). On restart everything is up & running normally again. Read somewhere that they're the IDEAL few things to do when installing new software. Never have a problem. G
