Answer Line: PC Safety Toolbox--Five Steps to Protecting Your System
I enjoy answering reader questions (even if I can't respond personally to every one). But often I'm the bearer of bad news. If only readers had backed up, used a firewall, or taken some other preventive step, there would be no problem with their PC.
As preemptive answers to your most frequent questions, here are five ways to avoid PC disasters. If you do only four of them, you're courting danger.
Security step one is a full backup. A reader recently wrote that she had accidentally wiped out a term paper. Unfortunately, she didn't have a copy on a floppy (or other removable storage medium).

Copy your data files daily. If you use Windows 98 or Me, back up these folders (you may not have all of them): My Documents, Windows\All Users, Windows\Application Data, Windows\Desktop, Windows\Favorites, Windows\Local Settings, Windows\Profiles, Windows\SendTo, and Windows\Start Menu. In Windows 2000 and XP, everything you need to back up is probably in the Documents and Settings folder; but in that folder, don't back up the History, Temp, and Temporary Internet Files subfolders.
Automate full backups (which copy every file in your data folders and run once a week) and incremental backups (which copy only the files created or altered since the last backup and run daily). I start my automated backup routine at the end of every workday. Consult Scott Dunn's June Windows Tips column on automating tasks (such as backup) when Windows shuts down.
