Hello Pondus,
I have posted the logs after running aswMBR.
The avast notification keeps on popping up everytime I open my laptop.
What should I do now?
Thanks,

Hello-
I need your help on how to get rid of this MBR:\.\PHSYICALDRIVE0 please… :-\ :-\ :-
Thanks,
Jared30

Download TDSSKiller from here:
http://support.kaspersky.com/downloads/utils/tdsskiller.zip

Run the TDSSKiller.exe file;

Wait until the scanning and disinfection completes. A reboot might require after the disinfection has been completed.

Post the log please.

Thanks Left123,
I have downloaded it and I see here
Malicious objects
backdoor.win32.sinowal.knf option Cure
Suspicious objects
locked file option Skip

then click Continue?

Hi Left123,
After I clicked on “Reboot” the computer didn’t restart and I didn’t see any logs. Will it pop up automatically after disinfection completed? I just clicked on Report,not sure if this is the log you’re looking for

If no reboot is require, click on Report. A log file should appear. Please copy and paste the contents of that file here.

If a reboot is required, the report can also be found in your root directory, (usually C:\ folder) in the form of “TDSSKiller.[Version][Date][Time]_log.txt”. Please copy and paste the contents of that file here.

If a suspicious file is detected, the default action will be Skip, click on Continue.If an infected file is detected, the default action will be Cure, click on Continue.

Hi Left 123,
I have posted the report. Please see above log.
Thanks so much for helping. I’m not getting any pop ups that my pc is infected or something.
Thanks again :slight_smile:

Did u installed previous of the infection some backup programm?

I’m sorry but I’m can’t understand this. Are you asking me if I install something or if I backup something?

If u installed some program … like a backup program or something ?

I only installed TDSSKiller. That’s what Left123 told me to install to get rid of the malware.

TDSSKiller does not have an installer.
