computer gurus, need some advice

[aussie]

i would get rid of avg and install avast . go into user accounts and create a new user account and see if the pc works ok . then do a scan with avast and see what comes up. did this happen all of a sudden or it been getting slower with time . when u create a new user account all the setting on that account go to default and sometimes u cant clear a viris on the same account try it see how u go i can help u .if u had some sort od chat line it would be easier good luck . remove avg before you install avast. also search and destroy is a good tool free to download and use
