Process activity
The DeepScan creates the following process(es):
taskkill.exe:1832
taskkill.exe:1536
sc.exe:1824
rundll32.exe:1672
cacls.exe:1752
The DeepScan injects its code into the following process(es):
%original file name%.exe:1600
Mutexes
The following mutexes were created/opened:
No objects were found.
File activity
The process %original file name%.exe:1600 makes changes in the file system.
