Hi

This should not be a problem. avast! 4.8 Home works with Windows 95 & 98.

When you say “press the button”, do you mean:

Right-click on “a” in System tray > Updating > iAVS Update

Are you getting any errors, like this one below ?

“Not enough storage” error when updating the virus database

If so - See, http://forum.avast.com/index.php?topic=45169.0.
