i did a clean install , my problem is afterward , i came here and got my virus protection and downloaded free window registry repair program and the program keeps tellen me i have HKEY-USERS and HKEY-MACHINE and the first thing the program recognises is a non existing file %microsoft office% this was the extention file from updates that dropped the trojen , this i found out on my first go around , i even had ppl call my house claiming to b mt net provider and transfering me to microsoft claiming they would remove it for $250 bucks , my clock doesnt work right and my scroll and other features of windows arnt acting right , i still get screen flashes, if need be i can do another install, ive called a few shops n town they all a hundred to fix it , i keep no info on my pc , no bank nothen like that , do u think i should try another install , when i did do the new nstall i had to call ms bcause some updates would not take and my evntvwr shows all kinds of failed failed failed

 

i posted n the software forum was advised to do a full reformat of xp , i have a question i just saved the program disk kill from here to my desk top , once i run this program then i would reinstall xp ; on my my disk it only has 2 options quick and custom , custom wants to partition the drive i dont actually need to do that , so if i run the killdisk program i can then do the quick install ? then of course ms up dates after ??
