Viruses and worms

I hope someone can help me.

After running AVAST boot scans, MalwareBytes, HerdProtect and Adware Cleaner, my friend’s computer on bootup is still trying to connect to a number of malicious urls. Here are some excerpts from Avast’s nshield.txt log:

13.02.2015 22:58:08 Network Shield: blocked access to malicious site http://reddie.net/3131/TrimInstance_142244772264900.dll ([37.48.117.50]:80) [ C:\Windows\System32\svchost.exe ( 1216 ) ]

14.02.2015 07:28:22 Network Shield: blocked access to malicious site http://epictory.com/3131/IndepthFunc_142243499717666.dll ([37.48.117.50]:80) [ C:\Windows\System32\svchost.exe ( 1008 ) ]

14.02.2015 08:23:33 Network Shield: blocked access to malicious site http://blackfight.info/3131/desktopbeautifier_142241602488537.dll ([37.48.117.50]:80) [ C:\Windows\System32\svchost.exe ( 1004 ) ]

I am attaching the log files that the forum recommends.

I appreciate any help that a malware analyst can provide.

Thank you!

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

Thank you sooooo much…

You are amazing!!! I have attached the fixlog.txt file as well as three log files from Adware Cleaner that were generated at about the same time. The AVAST nshield.txt log did not show any connection attempts to the malicious urls after I applied your fixlist.txt file.

I would love to know how you worked your magic!

The computer seems to be behaving perfectly!

Subject to no further problems :slight_smile:

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

https://dl.dropboxusercontent.com/u/73555776/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

https://dl.dropboxusercontent.com/u/73555776/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 :wink:

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