I am running Windows 10 Home. I opened what I believe is to be an infected video codec file called "Ultra XVid Codec Pack." I received an error during the installation.

 

Then I started receiving pop-ups from ESET NOD 32:

 

Threat found

Object: always a website ending in .php

Threat: Win32/Botnet.Other trojan

Information: connection terminated

 

These pop-ups would happen every second with each one a different website ending in .php would show up

 

I installed Malwarebytes and did a scan. The software identified a few system files that were infected with Sathurbot.E.

 

I quarantined those files with Malwarebytes and now I don't receive any pop-ups from ESET. However, ESET did not quarantine them, just identified a general threat (as in the example above)

 

Knowing that Sathurbot.E changes the name of system files and can cause problems in the long run, I have these questions:

- I am wondering if I need to "reset" my PC (through the Windows settings that re-installs Windows all over again). Or whether the quarantine is enough? If the files are quarantined, does that mean they are unuseable and can cause issues down the road?

- Have I done all that needs to be done or is there more that I need to do?

- The Malwarebytes software I installed is a trial version so after that ends, I am wondering what would happen to the quarantine files

 

Thank you!

One more Q - how do I figure out when Sathurbot.E was installed to make sure that it was the one that coincided with the earlier error (an not an older infection that was just identified when I installed Malwarebytes)? Thanks!

------------------------------

One or more of the identified malware is known to use a backdoor, that allows attackers to remotely control your computer, download/execute files and steal system, financial & personal information.

Banking and credit card institutions should be notified of the possible security breach. Please read the following article for more information: How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
 
Whilst the identified malware can be removed, there is no way to guarantee the trustworthiness of your computer unless you reformat your hard drive and reinstall your Operating System. This is due to the nature of the malware, which allows a remote attacker to make any kind of modification.
