OK, a little clarification:
1. there's no Virus Page in the Home version; the Virus Page is accessible only from the Enhanced User Interface (in the configuration of a task) - which the Home version doesn't have.
2. the screen-saver
always stops when a virus is found - no matter if its "Virus Page" contains the "Stop" action or not, no matter if it's the Home or Professional version.
You may call it a bug... I'd rather call it a "feature" for now. That's how the screen-saver was designed and it would require non-trivial changes (to the code) to modify this behavior. The fact is, however, that the Virus Page is somehow misleading here.
