Yasir... I'm afraid I don't understand exactly what you're asking about. Can you be more specific? What kind of computer do you have? Is it new or old? (If it's fairly new, it SHOULD come with appropriate anti-virus software already installed.) Which anti-virus program do you have? <file://C:\Documents and Settings\Jer\Application Data\Microsoft\Stationery\..\..\..\Desktop\Animated signature (Jerry).gif> Jerry Taylor SeniorTech http://www.seniortech.us <http://www.seniortech.us/> Personalized In-Home Computer Instruction for Senior Citizens and Retirees 585-964-3319 "Computers are not just for kids" -----Original Message----- From: seniortech-bounce@xxxxxxxxxxxxx [mailto:seniortech-bounce@xxxxxxxxxxxxx] On Behalf Of yasir arafath Sent: Friday, January 09, 2009 9:46 PM To: seniortech@xxxxxxxxxxxxx Subject: [SeniorTech] maintain system Hello sir, I need to how to maintain computers in virus and thier problems and precautions of all safety things in the computers.. if u have guide of problems and their solution with can u pls reply it would help me know some knowledge of the computers..
