I have had a Dell Precision m90 for 2 years and want to make sure i can keep it running as long as possible. I have had antivirus 09 but beleave i got ride of it. I currently use the following programs. Mcafee anti virus (i know alot of people dont like it but it seems to be ok plus i have a subscription until 2010) Spybot S&D and Malwarebytes i also have Ccleaner and i do disk defrags about twice a month. Is there any other programs i need to download to keep my computer running good? Thanks for the help Wanna kill these ads? We can help!
