Excessive AVG Temporary Files ?

I notice when I remove files with CCleaner 2.35 that most of the clutter files are labeled AVG. I run it about every day and this is typical. In the past, I don't remember that much being removed. Computer is mostly email with Outlook Express 6 and limited website search & browsing. No gaming or other data intensive applications. Does this seem like a lot of space to be accumulating every day?

I am using Win2000 on this computer and 99%+ Firefox. Thanks.
