This is our problem with AVG which we have installed in our home desktop. It's pretty good as an anti-virus but the issue is the updating that it does even without our permission. Once we boot, it readily connects to its website to do some updating (this is not clear to us what it is doing). Take note that in the setting, the updating is manual so the user should be informed. And sometimes when the computer was running for a time already, the AVG is continually connecting to its website hence the computer slows down. We checked on this by pressing ctrl-alt-del and the status of the browser is so large in memory use when in fact the browser is just on a display of a web page. For the AVG users here, do you have an issue like this?
