If you have multiple antivirus programs installed you are probably experiencing extreme computer slow-down or other performance issues as these programs consume system resources and battle each other. You’ll usually notice this immediately following the installation of a new antivirus package. If your computer’s hard drive is constantly working, and if you find any task you perform takes forever to load or complete, chances are you have multiple antivirus products installed. How does this happen? Quite often, either your computer shipped with a trial version of an antivirus program without your knowledge and you installed another. Or you could have tried to uninstall a trial version and the uninstall process failed.

If you do not have an antivirus program running and kept up to date, your system could be vulnerable to malware attacks.
