Does "avast! Junk" folder isolate infections?

[pfaoro]

Is it safe to open a message in the "avast! Junk" folder (because I suspect I might actually want it) and it turns out to be infected after all, does the fact of it being in the Junk folder isolate potential risks?

[Lisandro]

No. avast moves to Chest/delete the infected files.
The junk folder is used for spam (clean messages but spam).

Where do I find "Chest/delete"?  I paid for the full version

[Lisandro]

Left click the "a" orange icon.
Maintenance
Chest

How do I know to move a message to the Virus Chest, or does that happen automatically? I haven't been attacked; I just decided I ought to know. would a scan, for instance, identify which messages are risky?

In the expert settings for some of the shields, is a sub-section called "actions", this will determine what auto actions you want to take based on detection type (Virus, PuP, Susp.).  You can chose 3 auto-actions that Avast! will attempt to execute upon a detection, like [1st Move to Chest, 2nd Repair, 3rd Delete]  or whatever combination of 3 you can think of from a drop-down menu.

Total manual actions would be setting these to "Ask"

Move to Chest is the strongly recommended first action.  In the event of a false positive, you do not want to delete a critical system file.
