Hi! How can i boost up my system performance. I am currently using windows XP 2002 SP3. My system is core2Duo 2.2 with 1G DDR2 Ram. I have also problems with trojan so i deleted my windows and reinstalled it and installed symantec 10 which detects on daily basis different trojans. I am very confused about the antiviruses that which one i use and also about how to avoid threats when downloading some softwares and utilities. Kindly guide me and also tell me that where i can find a good tutorial on operating system mangement like complete overviw of win XP with all of its aspects. And can i change the user name of my TS account? Regards, ALi Nauman.
