There are some simple steps you must take to avoid becoming a victim of computer viruses and also stop spreading viruses to others. Here are some things that you can and should do.
Email Issues to watch
Never open an e-mail with an attachment you were not expecting.
The latest batch of virus programs is often spread by E-mail. Even if your anti-virus program does not warn you about the attached file and even if the email appears to come from someone you know, do not open it if you were not expecting it, and if you were expecting it, only open it AFTER scanning it with your up-to-date virus software.
Scan ALL incoming email attachments (regardless of who sent them).
Be sure to run each attachment you plan to open through the anti-virus check. Do this even if you recognize and trust the sender; malicious code, like Trojan horses, can slip into your system by appearing to be from a friendly source.
Turn off the ‘automatic preview’ in your email program.
Automatically previewing an email message has the exact same effect as opening and reading an email. One of the newest internet worms, Trojans, and viruses simply need to have an email message read in order for them to be activated. Turning off the preview feature allows you to scan any email BEFORE you actually read it.
Disk Issues to watch
Don’t boot from a floppy disk.
Floppies are one of the most common ways viruses are transmitted. If you are using a floppy while working on your computer, remove it when you shut the machine off or the computer will automatically try to boot from the floppy, perhaps launching any viruses on the disk.
Keep your web browser settings to their highest security level.
It’s a pain to get the warning messages on every other web page you visit, but it’s the best way to protect yourself — especially if you use Microsoft Internet Explorer and Outlook.
Don’t download programs from the Web.
Make regular back-ups of important data
Make it a habit to back up all of your most important files at least once a month. Store the back-up discs in a safe place.
Clean any virus/worm/Trojan off your computer
Using your antivirus software, perform a full system scan of your PC, hopefully, it will detect and remove the virus. If a virus was detected, restart your computer and run the full scan again. Sometimes the virus will keep reappearing, due to the evolving nature of viruses. Symantec is particularly fast at providing removal tools should you ever get a virus or worm infecting your computer.
What is a removal tool? Well simply put it is simple software that will scan your computer for infections, and then remove them from your machine. You most often need this if your machine got infected BEFORE you installed antivirus software.
Top Considerations for PC Protection
And the final and most important two things to do to keep your computer clean and make sure it does not spread viruses to other computers…
Install a Firewall
If you use a broadband/high-speed method to access the internet, you need to get a firewall. A firewall is a program that defends your computer from hackers who attempt to gain direct access to your computer over the Internet. There is a very good firewall program called ZoneAlarm that will do the trick if you use Windows.
Install and use a high-quality anti-virus program.
This is the key to protecting your computer. Buy one of the major anti-virus programs — Norton Anti-Virus, PC-Cillin, or McAfee Anti-Virus. The primary benefit of the commercial packages is the frequency and ease of updating the virus definition files that these programs use to detect viruses. With new viruses popping up all the time, unless your protection software is kept updated, you start to become ever more vulnerable to infection.
Get immediate protection.
Configure your anti-virus software to launch automatically on start-up and run at all times. This will provide you back-up protection in case you forget to scan an attachment or decide not to. And in case you forget to load up your anti-virus software, configuring it to start by itself will ensure you get immediate protection anyway. The top antivirus software programs all do this (but only if you have one installed on your computer). You do have current antivirus software installed right? If not, you can go to this page for more information on why you need antivirus software and how easy it is to use.
