Security Levels Set High. One of the easiest ways to protect your computer is to make sure your security levels are set on the highest level. Yes, it may be a pain to receive pop-ups notifying you about warnings on the websites you are visiting, but it really is the best way to protect your computer.
Firewall. If you have high-speed Internet access, you definitely need a firewall to prevent hackers from entering your computer. There are several firewalls out there; again, choose the one right for you and make sure you follow the company’s installation and use instructions.
Change your passwords. Don’t keep the same passwords for years and years – change them at least once a year. Many member sites already require you to do this, but be sure to do it for all programs. Keep a list of usernames and passwords handy to make these changes easier on you.
Back up. There are thousands – no, millions – of computer horror stories when it comes to backing up your hard drive. You must back up your files if you intend on keeping them forever – who knows when a computer will crash? Make a back up schedule and stick to it. Place your back up disks in a safe place just in case.
Avoid unfamiliar e-mail attachments. Most people who have e-mail accounts have encountered the e-mail attachment that really was a virus. Set your e-mail program’s security high, and delete any unfamiliar e-mails containing attachments – you never know when you will be plagued with a virus.
