Never install more than one antivirus program on your computer.

Antivirus is probably the most intensive process on your computer or laptop, so it is important that you do not have two installed at the same time.

If you do, you will find that your computer is much slower than it should be because both are trying to use resources.

We recommend that you look under “Add or Remove Programs” and try to remove all old redundant antivirus programs that you no longer use, and install only the selected antivirus program.

So if you are reading this while you are looking for a new antivirus vendor, after you have made a decision, remove the old vendor before installing the new antivirus vendor of your choice.

To help you, you can find the name of your antivirus provider and installer on Google.
