The first detection TOSCDSPD.exe needs further investigation as it seems a legit file (the reason why sending to the chest is important), see below.
The second detection is an interesting one it looks like this quarantine folder isn't encrypted
The third detection looks good as using cracks is a high risk business not to mention any legal/moral issues, who can you complain to when using a crack that your system got infected
When done, and windows has booted, right click the avast 'a' icon, select avast! Antivirus Chest, the only part that interests you is the Infected Files section.
I don't even know if avast's boot-time scan would scan attached devices on a boot-time scan, some might net even be recognised before windows boots (depending on your BIOS settings).

You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner and
report the findings here the URL in the Address bar of the VT results page. You can't do this with the file securely in the chest, you need to extract it to a temporary (not original) location first, see below.
Create a folder called Suspect in the C:\ drive, e.g. C:\Suspect.
Now exclude that folder in the
Standard Shield, Customize, Advanced, Add, type (or copy and paste) C:\Suspect\*
That will stop the standard shield scanning any file you put in that folder. You should now be able to export any file in the chest to this folder and upload it to VirusTotal without avast alerting.
If it is indeed a false positive, see
