IT Business Edge Knowledge Network partner Rich Robinson, who runs the Web site Windows Guides, recently uploaded a pair of PC security and maintenance guides. Here's a short look at both of these resources.

PC Security Handbook

This handbook is designed to help you find ways to protect your Windows XP/Vista/7 PC and ensure your data is safe. This guide helps you avoid malware, spyware and viruses, keep your computer and browser up to date and backup your data online.

PC Maintenance Handbook

This handbook is designed to help you find ways to maintain your Windows XP/Vista/7 PC and ensure your PC remains clean and speedy throughout its life. Computers quickly get bogged down by junk files, invalid registry entries, a fragmented hard drive, spyware, adware, low disk space, and more. This guide helps you find and remove malware, uninstall unnecessary problems, optimize your system, defragment your hard drive and backup your data.
