Thank you for sample. This is variant of Backdoor:Win32/Poisonivy.E
Copies itself to %systemroot%\system32\taskeng.exe
Runs every Windows boot through
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and
HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components under
{3C65BAA2-8F50-716F-4A7F-B87ADCC65E0E} key. Upon deletion rewrites them back.
When started - executes Internet Explorer and injects to it payload code. Payload contains link to hmm.no-ip.info and protects taskeng.exe from being deleted (keeps opened handle of file).
Contains blacklist with antivirus executables.
avguard.exe
sched.exe
avgnt.exe
avcenter.exe
avconfig.exe
Topic title changed for actual malware name.
