Have older Dell Dimension 32/bit with Win XP Prof 2002. I have installed CA security suite from my ISP, which is a huge program and uses 100% of CPU on start-up & shut down, slowing everthing to a snails pace. I have removed evrything I don't need using 30 day free Revo Unistaller Pro, but when I try to access CA's Firewall to add programs to the exception rule, it will open, then freezes along with Firefox tabs and anything else. Can't even shut down from start menu. I want to get rid of CA(although it is a good program, it's too big), and go back to using my Win Firewall(or another better free firewall that's good for more than 30 days trial) and some other free internet security program that is easy, runs in the background and doesn't take all my resources and isn't just a 30 day free trial till you buy the program. I am also trying to install a wireless adapter so I can drop my ISP and use the free city/county signal as no work for 20 months! == This happened == A few times a week == Trying to access CA security Suite Firewall
