virus chest & view last scan

I have avast 4.8 home edition.

Q1. How to repair infected files in virus chest?

Q2. How to view last scan results?. when I right click on the user interface, I am able to see “Last scan results” but unable to open it.

Generally only executables could be repaired with the help of VRDB (virus recovery database from avast). You can repair before sending to Chest, into Chest, there is not such a possibility. You can extract the file, but avast should detect it again and try to repair.
Which file you’re trying to repair?

In Home version, when you close the interface the results aren’t available anymore, only in the Professional version.
