…and back up your system before you install.

I’ve had a PC since 1986, and anti-virus software since Norton AV v. 1, so I know what I am doing.

I recently installed BitDefender Internet Security 2011, but found it slowed down my system, especially internet activity, to a point it was almost unusable, so I uninstalled it. I reinstalled BDIS 2010 and looked for another AV program. After reading some good reviews of KIS 2011 I went to Kaspersky’s Web site and downloaded the 30-day trial version of Kaspersky Internet Security 2011.

Before I installed it I uninstalled BDIS 2010, deleted the folders, and purged the registry. The install went smoothly, and it updated itself. Once running, it seemed to run well. I perused the settings but didn’t change anything.

Then I started Firefox. I discovered KIS turned off all my themes and extensions, and wouldn’t let me reactivate them. I also run a Task Manager all the time. Almost no running tasks showed up in the Task List. I decided this was unacceptable and I uninstalled KIS 2011.

Even after I uninstalled KIS 2011 and rebooted, the changes it made remained. I still could not run Firefox’s themes or extensions, and running tasks were still missing from Task Manager.

I ended up restoring my Acronis image in order to regain control of my computer.

I realize it KIS 2011 works well for some people, but not for me. I’m glad I didn’t pay sixty bucks for this.
