I got phished, worried about a backdoor [Solved]

A very clever scam induced me to run an executable file I was tricked into thinking was a legitimate update for TeamSpeak 3 (the sound plugin scam, if any of you are familiar). I realized it was a scam attempting to steal my Steam account moments afterward and promptly ran a fast Malware Bytes scan and then rebooted in safe mode. MalwareBytes detected and deleted something, but I'm worried that it was merely the trojan executable and not what it downloaded onto my machine. I then used Comodo Cleaning Essentials, Avast, and Kaspersky's TDSSKiller kit. None of them detected anything.

 

As far as I'm aware, the trojan runs client32.exe and downloads a remote access program called Ammy Admin renamed to winsvchost. This is all stuff I've heard from other people who were phished.

 

I took care of my passwords, changing them from a separate, uninfected machine, but I'm worried that there might still be a backdoor on this machine. I'm afraid to relog from here. Is there anything more I can do?

 

EDIT: I'm now receiving random crashes in Firefox. I attempted a system restore to an earlier point but received an error message:

Apparently it rewrote some files but didn't have permission to deal with system files for some reason. Firefox was fixed, though, and no longer seems to crash. I ran FRST again and the logs have been updated accordingly. I'm very sorry for the inconvenience.

Hi sorry for the delay. Your system did restore it is just reporting that Avast would not let restore replace the virus defs... that is a quirk of Avast


As it stands I can see no apparent malware on the system related to a steam hijack

There are a few adware components that need to go. Are you experiencing any problems ?

CAUTION : This fix is only valid for this specific machine, using it on another may break your computer

Open notepad and copy/paste the text in the quotebox below into it:

Save this as fixlist.txt, in the same location as FRST.exe

Subject to no further problems :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:

Remove tools

Download and run Delfix
Select the options as shown
delfix.JPG
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

CryptoPrevent install this programme to lock down and prevent crypto ransome ware

CryptoPrevent.JPG

Malwarebytes

Update and run weekly to keep your system clean

Unchecky

Click on the link above to be taken to Unchecky.com
click the very large Download button.
click Save
Click Open folder
Right click on the Unchecky_setup and choose to Run as Administrator
Once open click the Install button.
Then click on Finish
Unchecky is now installed and will help you keep unwanted check boxes unchecked, this is a fire and forget programme ;)

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.

To learn more about how to protect yourself while on the internet read this little guide Best security practices Keep safe :wave:
