Try this:

Click on RCU page, such as Reviews. (I have done this one myself).

When you get the AVG warning box, simply acknowledge it, by clicking on the close button on the box.

Now, continue surfing the page.

When you click another link, such as a photo, you will get the AVG warning again. Again, close the box and try to surf the RCU page you clicked onto.

It is annoying as hell, but you can get through at least a little bit.

This is with Chrome as my browser. No clue how IE acts.
