Maintenance

Use System Restore... Always create a restore point using System Restore when installing or deleting software. You'll find the applet in Accessories > System Tools > System Restore.

73	...unless you're infected If your computer has been infected by viruses or spyware, System Restore may actually preserve these Net nasties. Temporarily disable System Restore and perform a full system scan. After you've cleaned your PC, delete old restore points and start fresh.

74	Don't download from strangers Before you install anything, ask yourself if the software is trustworthy. If you don't have a good reason to trust it, pass.

75	Blast spyware Prevent browser hijacks and other Internet-related annoyances by keeping updated copies of Lavasoft's Ad-Aware and Spybot-Search & Destroy on your hard drive. Both are freeware and help immunise your computer against potential threats.
