Just found this behavior, files in Virus Chest are gone after this procedure.
- Put something into Virus Chest
- Extract pseudo-malware executable (FP or something) to excluded(R/W) directory
- Right click exe and select "Run in avast! sandbox"
- avast detects it, select "Block"
- Now all files in Virus Chest are gone!
Sometimes, even you select "Block", exe file is also disappeared.
Windows 7 32bit SP1 / avast! Internet Security 8.0.1483
