Binary numbers

We live in a dangerous world, both offline and online. While terrorists and untreatable diseases put our lives in danger in the physical world, our virtual world, the World Wide Web, is threatened by computer viruses, spyware, malware, root kits and other computer security threats. Fortunately, these tips should help you learn how to protect your personal computers from the threat of viruses.

1. Install anti-virus software. This is your first line of protection against computer viruses. You can download and install antivirus software on your computer to make sure that computer viruses do not infect your files and programs. The best antivirus software has to be bought, but you can download free trial versions and use them for as long as one year. Make sure to update to your antivirus software regularly. Ten of the most popular antivirus software are:

  • Bitdefender Antivirus
  • Kaspersky Antivirus
  • Webroot Antivirus
  • G DATA Antivirus
  • ESET Nod32 Antivirus
  • ParetoLogic Antivirus Plus
  • AVG Antivirus
  • Vipre Antivirus + Antispyware
  • F-Secure Antivirus
  • Trend Micro

2. Enable a firewall. A firewall is an application that prevents computer viruses. It is an application that prevents computer viruses from infecting your computer by preventing potentially outside connections to your computer. If you are using the Windows XP operating system, then you have a built-in firewall. You can check this at the Networking and Internet Connections tab in the Control Panel. If you feel your computer is still not protected by this built-in firewall, you can choose from the following commercial software:

  • ZoneAlarm Pro
  • Outpost Firewall Pro
  • Norman Personal Firewall
  • eConceal Pro
  • Webroot Desktop Firewall
  • Injoy Firewall
  • SurfSecret Firewall

3. Update your operating system regularly. One of the best things about buying an original operating system is that you get regular updates to fix bugs and other security loopholes that may harm your computer. For example, Windows XP automatically searches for updates on the Internet and notifies the user if it's now time to install the updates.

4. Use spam protection. Many computer viruses get into your computer as email attachments. Remember the "I Love You" virus? The lesson is not to open emails from unknown sources, especially if it looks like spam. Mark emails that look like spam as spam so that you won't have to get them in your main inbox and accidentally open them. For further protection, use anti-spam software. Some of the most popular anti-spam software for personal computers are:

  • MailWasher Pro
  • OnlyMyEmail
  • Cloudmark Desktop
  • POPFile 1.0

5. Avoid installing suspicious software. Some computer software or programs are hotspots for computer viruses, or they contain viruses themselves. If you are not sure about the publisher of the program, then don't install it. If you need to install the program for work purposes, then check the Internet for feedback on the software or program. That way you'll have an idea if it poses significant harm to your computer.

Just follow the recommendations presented above and you can be sure that your computer stays virus free for a while.
