Title: Avast! keeps popping up with differentia.ru. Help!
Post by: REDACTED on August 26, 2015, 05:28:59 PM
Hi! Avast keeps popping up saying:

"Avast Web Shield has blocked a harmful webpage or file.
Object: http://differentia .rum/diff.php
Infection: URL:Mal
Location: windows/SysWOW64/msiexec.exe"

I have once tried getting rid of this and for a while it disappeared and I stopped receiving the pop-ups. Earlier today, a friend of mine plugged in her flash disk and the pop-ups began again. I figured that when it stopped popping up the file/infection never really disappeared from the system.  :'(

I've already installed programs like Spyhunter4, Malwarebytes, and have been checking constantly through Avast Browser Cleanup.

Please help! I really want to get rid of this malware once and for all. I saw a forum that gave a specific link (Farbar Recovery Scan Tool) that helped fix the problem. I was hoping someone could help me out with that.

Thanks!!

P.S. I'm currently scanning with Malwarebytes and Spyhunter4 again. Will post log file once scan is complete.

I have attached the 3 needed logs (MBAM, FRST, Addition).

After I scanned using MBAM and it detected 11 suspicious activities, I selected to quarantine them and restarted my computer.

I've made the note and I've pressed Fix but FRST ended up "not responding" after a while. Explorer also isn't responding.

Should I force close / shut down and restart?  :-\

Aye .. Does it say what stage it is at ?  I.e. emptying temp
Title: Re: Avast! keeps popping up with differentia.ru. Help!
Post by: REDACTED on August 26, 2015, 08:37:22 PM
It says "Deleting temporary file: C:\Windows\Temp"
Title: Re: Avast! keeps popping up with differentia.ru. Help!
Post by: essexboy on August 26, 2015, 09:46:47 PM
OK it can do that if you have not emptied them before :)

After the reboot was a log generated

Unfortunately, until now, Farbar isn't responding. Also the desktop and explorer. I can move my mouse and transfer using alt+Tab but that's it.

Any advice? I'm afraid if I force shut down, it'll do harm to the system.  :(

Here's the Fixlog file and the AdwCleaner log files.

I had to force close my computer during the FRST scan since it really was no longer responding.

Have the alerts ceased...  It appears that FRST was unable to clear your temps for some reason. 

Clear Cache/Temp Files
Download TFC by OldTimer (http://oldtimer.geekstogo.com/TFC.exe) to your desktop

I no longer receive the pop-ups/alerts from Avast.

Also, I've run TFC and rebooted manually. Attached is the log.

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 (http://www.bleepingcomputer.com/download/delfix/)
Select the options as shown
(https://dl.dropboxusercontent.com/u/73555776/delfix.JPG)


: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article (http://www.forbes.com/sites/eliseackerman/2013/01/11/us-department-of-homeland-security-calls-on-computer-users-to-disable-java/)

I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser (http://www.geekstogo.com/2600/how-to-disable-java-in-your-web-browser/) and How to unplug Java from the browser (http://krebsonsecurity.com/how-to-unplug-java-from-the-browser/))

If you do need to keep Java then download JavaRa  (https://singularlabs.com/software/javara/javara-download/)
Run the programme and select  Remove Java Runtime.  Uninstall all versions of Java present
Once done then run it again and select Update Java runtime > Download and install Latest version
(https://dl.dropboxusercontent.com/u/73555776/javara.JPG)


Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes (http://www.malwarebytes.org/mbam-download.php)

Update and run weekly to keep your system clean

Unchecky (http://unchecky.com)

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  (http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/)Keep safe  :wave:

All noted! I'll make sure to scan and keep my system clean to make sure this doesn't happen again. :)

Thank you so much for your help!   :D  :D  :D
