How To Keep Your Computer From Spreading Viruses
There are some simple steps you must take to avoid becoming a
victim of computer viruses and also stop from 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 are 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 it).
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. My 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.
Web Based Issues
Keep your web browser set to its highest security level.
Its a pain to get the warning messages on every other web page
you visit, but its the best way to protect yourself - especially
if you use Microsoft Internet Explorer and Outlook.
Don't download programs from the Web.
Unreliable sources such as Internet newsgroups or Web sites that
you haven't heard of may be willing providers of viruses for
your computer. Avoid downloading files you can't be sure are
safe. This includes freeware, screensavers, games, and any other
executable program - any files with an ".exe" or ".com"
extension, such as "coolgame.exe." Check to see if the site has
anti-virus software running on their side. If you do have to
download from the Internet, be sure to scan each program before
running it. Save all downloads to one folder, then run virus
checks on everything in the folder before using it. Regardless
of where you download from, ALWAYS scan downloaded software.
Routine Maintenance
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 (Details: ht

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. Sometime 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
infesting your computer.
What is a removal tool? Well simply put it is a 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.
