Hi Pondus,
As you go through the original posting all I find mentioned is a decompression bomb flagged.
Decompression bomb — an attack that targets antivirus software during malware analysis.
The attack occurs when antivirus decompresses or unpacks a decompression bomb and attempts to run it in a virtual machine.
Decompression bomb may crash the antivirus and/or subject the system to a denial of service attack by heavily loading the CPU.
One should then boot into safe mode, and run the av again. if it still cannot remove it, youll have to do it manually,
or scan with a non-resident online scanner or use ClamWin,
