Antivirus software are complex programs designed to identify, neutralize or eliminate malicious content that invade your computer. Many people over a period of time will change from one brand of antivirus software to another. Antivirus software is big business and today there are many flavors and options available.
For example; There are (3)-three “FREE (for personal use)” reputable antivirus packages that are widely recognized (see below). I prefer any one of these over the major brand antivirus software packages due they are light on system resources, and are not bloated. As a matter of fact, I cannot remember ever having a commercial (paid for) version of an antivirus program on any of my computers at home.
The points of this article is to educate you to the fact that there are FREE antivirus software options available and that follow-up research may be required to “completely” uninstall (remove) antivirus software from your system in the event you desire to install another antivirus program.
Antivirus software, when running on your system, is hooked into many areas (i.e. registry, file system, resident memory, etc…) and uninstalling it can leave debris behind that can cause other systemic issues. Antiviruses are like viruses; they can be hard to get rid of… To prove my point, I researched (9)-nine antivirus programs and found that every one of them had supplemental removal instructions or tools, in addition to following the typical Add/Remove console process found in Windows. I have listed the sites below for convenience and reference. During this research I also found that locating this information was often buried deep in their sites and was not readily accessible.

You must use the Microsoft uninstaller found in Add and Remove Programs within the Command Console.

Great post with some very valuable info. Getting off old security apps completely is tough and no doubt contributes to the famous “bit rot” if not done properly.
I quite agree – getting all of an AV application deleted can be a real
challenge. I recently removed an AV suite, which, as part of its install
process installs a root kit.
Thanks for the comment.
