ran combofix and it found a infected services.exe, restored and restarted machine.
Cannot find any log file in c:/

Any ideas?

6

If there is no Combofix.txt log in C:\ then again disable antivirus and just re-run Combofix.

7

no luck. Tried opening combofix again and it goes through the ‘extracting’ etc…, finishes and then thats it.
No log file.

8

just creates a file on c:/ called 32788R22FWJFW

Ok. Stop Combofix. Restart your computer.

Hi

Combobox finally started running (in console window).
Went through 50 stages, then I got blue screen ‘windows encountered a problem’.

Windows restarts and loads back up. Once loaded it pops up saying windows recovered.

No log file. I’m running it again.

11

it won’t run now, starts up console and before it gets to stage 1, windows need to restart blue screen

12

Ok. Lets forget Combofix for now.
We need to fix this otherwise …

Download TDSSKiller and save it to your desktop

Execute [b]TDSSKiller.exe[/b] by doubleclicking on it.

[*] Press Start Scan

[*] If Suspicious object is detected, the default action will be Skip, click on Continue.
[*] If Malicious objects are found, select Cure.

Once complete, a log will be produced at the root drive which is typically C:\ ,for example, [b]C:\TDSSKiller.<version_date_time>log.txt[/b]

  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.

[*] Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.

Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
A report will be created in your root directory, (usually C:\ folder) in the form of “TDSSKiller.[Version][Date][Time]_log.txt”.
