ok, some of you are asking what kinda maintenance, what programs... let me tell you on a normal system to keep it upto date we need certain programs to be upto date. Like you need to schedule virus defs updations say every week, windows updation every month, spyware updation, firewal, and we need to do diskclean up every week or so. Defrag every fortnight. And any other software you use on your computer. Ain't it bugging ???
