I need some help on my parents computer. A. the computer has a 598 MHz P3 and i was wondering if i can just drop a 1 gig MHz P3 in its place?? Also, i have a problem with some adware. I have used Norton, Mcafee, and some other software and they can not remove the adware. I keep getting a baloon on the bottom right of my sceen on Xp and it says that "you have a trojan and network virus you need to click hear to download a FREE scan" If you click it you come to a screen giving you three choices to download. They are all free scan only, you have to pay 29.95 to remove the adware they found on their free scan. So, can anyone help???? Thanks, Shelby
