How can you prevent viruses?

Answer 1

You Need The OS Disk, I.E The Windows XP Disk So You Can Re-Install It After The Process Is Complete. Instructions.You Need To Search For DBan Nuke & Boot, Download It And Burn It To A Disc. 1) First Restart Your Computer With The DBan Nuke And Boot CD Inserted. 2) You Need To Choose The Option To Boot From A CD. 3) Then Follow The On-Screen Instructions, The Proccess Time Varies Depending On The Amount Of Data Currently Stored On Your Computer And The size And Capacity Of Your Computer's Proccessor And Its RAM. 4) Upon Completing The Nuke & Boot Proccess If It Doesn't Automatically Restart Then Do It Manually, Then Insert Your OS Disk, Then Obviously Set Up Your OS As If The Computer Is/Was Brand New. I Hope This Helps You (Note: Rebooting Your Computer Will Get Rid Of All Viruses Present On The Computer, But Be Advised If You Do Not Want To Lose Any Data Then Back Up Your Files To A Disk) Thanks, Nathan
