These precautions can be a tutorial unto itself, and luckily, we have one created already:
Simple and easy ways to keep your PC safe and secure on the Internet.
Make your Internet Explorer 6 and below more secure.From within Internet Explorer click on the Tools menu and then click on Options.
- Click once on the Security tab.
- Click once on the Internet icon so it becomes highlighted.
- Click once on the Custom Level button.

It is very important that your PC has an anti-virus software running on your machine (you could free download ).This alone can save you a lot of trouble with adware in the future.
We can’t stress strongly enough how important it is for you to do five things for every PC you own:Secure your e-mail client against running unwanted scripts. If you use Outlook or Outlook Express and have not secured them.
Scan your computers by at least weekly to make sure they aren’t harboring viruses or worms.
Keep your ExterminateIt software up-to-date. AntiVirus software vendors update their virus lists on a regular basis.Make sure you visit your vendor’s Web site at least once a week to download the update.
Avoid running attachments (especially .EXE files) that come in your e-mail it may be Thursday.12th, even if they come from your friends, relatives or colleagues. The warped minds now writing e-mail viruses will do their best to lure you into running their viruses and worms by making them look like love letters, jokes or pornography. Once you or one of your friend succumbs to this temptation, the script will mail itself to everyone on that computer’s address list.
Make frequent backups of your data files, and keep some of your backups out of your pc.We like to burn CD-R backup discs on a regular schedule; CD-RW and Zip discs also work well.
