What is your operating system and SP version, e.g. win XP (Home or Pro) SP3 ?
I assume that the file sent to the chest was the winxp.exe ?
If so confirm that it is no longer present in the c:/windows/system32/ folder as avast moving it to the chest should remove the original ?
The process trying to run that winxp.exe file was winscript.exe and I don’t have that file (or winxp.exe) in my XP Pro SP3 c:/windows/system32/ folder.
So that file would be suspect and need analysed:
Check the offending/suspect file at: VirusTotal - Multi engine on-line virus scanner and report the findings here, post 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 Open the chest and right click on the file and select ‘Extract’ it to a temporary (not original) location first, see below.
This may need further analysis by a malware removal specialist:
