Virus Prevention Tips

Virus Prevention Tips


We check-in computer systems for repair every day that have virus related issues to overcome. Some of these repairs end with a reload of the operating system and data transfer due to the type and severity of the infections. It is an expensive hassle for our clients. The question that we often hear is: "I have antivirus installed on

my computer. How is this possible?"

There are many answers to this question so we are going to look at them one at a time. Some are simple. Some, not so much.

Antivirus Software:

  • Non-existent: What our client thought was on the system was not actually installed.
  • Expired: The antivirus of your choice was installed but had expired and was not protecting your computer anymore. Some security software is offered as a trial which soon runs out.
  • Inferior Product: Yes they are out there. Even fully installed, up-to-date and active (not expired), there are some products that just are not doing a good job of protecting you. (COUGH COUGH McAfee COUGH)
  • More than one: Having two "active" anti-virus systems are in most cases worse than having nothing. Their conflict could corrupt files and cause damage to your operating system. More protection does not equal better protection.


Some other factors that are not related to Anti-Virus programs can contribute to a greater risk of infection.

Things such as:

  • Modern Operating System: Never use an outdated operating system. If it's not supported anymore you face a HUGE risk of data theft and virus infections. This is currently the case with Windows XP.
  • Missing Operating System Updates: Make sure that your system is current with ALL critical updates installed.
  • Outdated Browsers: Use browsers that you trust. e.g. Google Chrome and/or Mozilla Firefox. Update them when prompted to.
  • Browser Plug-ins: Make sure that your Java, Flash, Shockwave and Silverlight applets are up to date.


On top of the tips above, remember that a good Anti-Virus can only bring you so far and can never replace safe computer use. Safe browsing is the best way to reduce your chances of getting infections.

Here are general pointers that can help:

  • Proper Addresses: When using a web address ( make sure that it's typed correctly. If you go to, that address could take you somewhere you might not want to go.
  • Proper Clicking: When you click on something, a picture, a button or a link, it can take you anywhere. Double check where it goes by hovering your cursor over it and taking a look in the lower left hand corner of your browser. It should tell you the address of where it will take you.
  • Proper Email Use: If you have a link in an email, even from someone you trust, think twice and use the above tip to confirm where it is going.
  • Proper Downloading: We have provided a link HERE that is a picture of a webpage. This is a prime example of how confusing things can be. Take a look! This shows a few download buttons, however the real button to download this software is a full screen further down. The other buttons may be traps! You have to look twice to make sure what you are clicking on is what you want. It's difficult. We know.
  • Proper Cleaning: We meet people who have attempted to tune-up their systems with software they see on TV Ads or online offers. Please don't fall for this. None of them, that we have seen or tried, have done a thing and many have made things worse. One even infected our test system.


Mostly we find that the computers being brought in for virus removal have been infected unwittingly by the user. They installed a program or update that they think is one thing when it's another. YOU are the BOSS and if you downloaded it and clicked on "Yes", you MUST know what you are doing. Your antivirus does not scan this type of activity as thoroughly. Be careful out there.

Businesses Pointers: Do you have a system that is running your business? Treat it like a tool. Try to use it as little as possible for personal things, especially games.

Homes with Children/Elderly:Set up a password protected administrator account. Set the other accounts, including your own, as "limited" so that you cannot inadvertently download and install badware!
