Contract a virus

Here are five sure ways to infest your computer with Web-borne viruses or security threats:

“ Don’t use free software tools like Ad-Aware Personal Edition and Spybot Search and Destroy that scan and remove nasty programs.

“ Click on attachments in e-mail from people you don’t know.

“ Never use an Internet firewall.

“ Click on banner ads when visiting “free” music or celebrity sites. Especially click ads for free software or some great deal.

“ Let your teenage son and his friends use your computer whenever they want, no questions asked. Don’t bother installing parental controls over sites they visit.
