The win32:KillApp [PUP] detection you mentioned doesn't appear to be present in the list, whilst you don't give the malware names in the list, we are very familiar with the win32:KillApp [PUP] detections and the greatest majority they are on HP systems in the c:\HP\Bin\ folder.
Do you have an HP system ?
On the list of detections, what action did you take at the time of the detections ?
Re the first two detections, C:\WINDOWS\Temp\unp*.tmp:
I believe that should be in the C:\WINDOWS\Temp\_avast_ folder as the _avast_ fo;der is where avast sends/unpacks files that it is going to scan ?
The unp999999.tmp file format is what avast names its temporary files which it is about to scan in that location.
The last to detections in the C:\System Volume Information folder, I suspect may be related to the first two detections, if you deleted them then the system restore may have made copies (restore points) in the C:\System Volume Information folder.
All four of those can safely be deleted.
The third detection in your list, is in your JAVA cache and is generally an indication of a java exploit associated with an out of date JAVA version which is Vulnerable to attack. Your version 6.0.13 is way out of date and you need to update JAVA. That too is safe to delete.
- I would also suggest a visit to this site, which scans your system for out of date programs that have patches to close vulnerabilities,
