Combo fix ran all day and nothing. I finally restarted my computer after it froze for about 30 min. now it is running again but has been running for an hour already.
this is the last thing that displays

“ComboFix will now start scanning your computer for known infections. This procedure can take some time, so please be patient.”

Please delete the Combofix.exe ( drag & drop into recycle ) and download fresh copy of Combofix.

Please try again to run the tool. Don’t wait all day, if you see that CF doesn’t run, reboot your computer and re-try it from safe mode.
I realy need to see Combofix log.

Hi theullrich,

Never post live links to malicious url, break them like with hxtp:// or wXw, so the unaware cannot get infected by clicking on them.
The url you reported has illegal and questionable botnet, see: https://www.virustotal.com/en/url/6539f25b68c07a994d03759ca60f10d1438babaea18436ca186459af86f0a7c6/analysis/1373064401/
I get an unreachable for the Quttera scan…
This scan says it all, look at the IDS alerts: http://urlquery.net/report.php?id=3563677

Okay, Zoek did a fantastic job but there’s still work to do. Your malware (rootkit) is a bit specific, we need to dig a little deeper.

You need to re-try to run Combofix ( instructions are on the last page ). Delete old Combofix.exe ( drag & drop into Recycle bin ) and download fresh Combofix copy.
Re-run CF and attach here fresh Combofix.txt logreport.

  • If CF fail again, let me know it, and move on Zoek. Same with zoek.exe. You will delete old zoek.exe ( drag & drop into Recycle bin ) and download new, fresh version of zoek.exe.

Re-run zoek.exe with this script:

filesrcm;
startupall;
DIR /S /A:L "%systemdrive%\*">>"%temp%\log.txt";b
C:\Windows\system32\services.exe;i
C:\Windows\SysNative\services.exe;i
firefoxlook;
chromelook;

Attach here fresh created zoek log
