Why does my computer say "Windows did not find antivirus software on this computer"?

I have AVG free, and have always had AVG free, but this message has not come up before. Why is it coming up now?

AVG now has newer versions out but they are no longer free. Often people have trouble running obsolete software. It's time to either upgrade to the new version of avg or find another security program.

What you have is probably is firewall or spam blocker
Most likely windows is not reconising as an anti-virus, and just another program.
Just go to the Control Panel -%26gt; Security and click on the "I have my own antivirus software..." to get rid of the message.
You probably updated windows, the older versions of xp didn't check for an antivirus, it can be turned off if it really annoys you, it doesn't mean that AVG isn't working any more though.
Chech that you have not accidentaly deleted any important files of AVG.Check in Control Panel-%26gt;Add or Remove Programs-%26gt;AVG. If its there and still Windows shows the message then some files may have got deleted.Reinstall the app.
If you can see AVG in the bottom right corner,click to make sure its running,if not you may have to install it again( first unistall) !
