Greetings,
This is the second computer I am requesting help on. The first had the Fake Google Chrome processes issue and now appears to be almost totally resolved. This computer as similar symptoms, except the multiple processes using high CPU are dllhost.exe with a Description of Com Surrogate. I have attached the Farbar RST logs.

Hello,



They call me TwinHeadedEagle around here, and I'll be working with you.



Before we start please read and note the following:
  • At the top of your post, please click on the "Watch thread" button and make sure to check Watch this thread...and receive email notifications. This will send an email to you as soon as I reply to your topic, allowing me to solve your problem faster.
  • Please do not install any new software during the cleaning process other than the tools I provide for you. This can hinder the cleaning process. Please do not perform System Restore or any other restore.
  • Instructions I give to you are very simple and made for complete beginner to follow. That's why you need to read through my instructions carefully and completely before executing them.
  • Please do not run any tools other than the ones I ask you to, when I ask you to. Some of these tools can be very dangerous if used improperly. Also, if you use a tool that I have not requested you use, it can cause false positives, thereby delaying the complete cleaning of your machine.
  • All tools we use here are completely clean and do not contain any malware. If your antivirus detects them as malicious, please disable your antivirus and then continue.
  • If during the process you run across anything that is not in my instructions, please stop and ask. If any tool is running too much time (few hours), please stop and inform me.
  • I visit forum several times at day, making sure to respond to everyone's topic as fast as possible. But bear in mind that I have private life like everyone and I cannot be here 24/7. So please be patient with me. Also, some infections require less, and some more time to be removed completely, so bear this in mind and be patient.
  • Please stay with me until the end of all steps and procedures and I declare your system clean. Just because there is a lack of symptoms does not indicate a clean machine. If you solved your problem yourself, set aside two minutes to let me know.
  • Please attach all report using
    fjqb1h.png
    button below. Doing this, you make it easier for me to analyze and fix your problem.

  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

This will be our last fix. Tell me how is your PC now?



FRST.gif
Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.

icon_exclaim.gif
Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on
    FRST.gif
    icon and select
    RunAsAdmin.jpg
    Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

Glad I could help. We will delete all used tools and I'll give you some tips to harden your security and learn how to protect yourself :)

The Importance of Software Updating:

In order to stay protected it is
very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.

Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.




Recommended additional software:
icon_arrow.gif
TFC - to clean unneeded temporary files.
icon_arrow.gif
Malwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gif
Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gif
McShield - to prevent infections spread by removable media.
icon_arrow.gif
Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gif
FiheHippo.com Update Checker - to keep your programs up-to-date.
icon_arrow.gif
Adblock - to surf the web without annoying ads!



Post-cleanup procedures:


Download DelFix by Xplode and save it to your desktop.
  • Run the tool by right click on the
    51a5ce45263de-delfix.png
    icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run and wait until the tool completes his work.
  • All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt)
The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.

Hello,

Hello, I'm having a problem with Com Surrogate (dlhost.exe - Com Surr) virus on my laptop. OS: Windows 7 Home Premium SP1, 64 Bit Operating System, 284GB HD, 4.00GB RAM, 2.13GHz, AVG Free 2015, Malwarebytes Anti Malware, SpyBot S&D... I have had this Virus for at least a month. My computer started reacting as though it had a typical Trojan, I ran Malwarebytes Anti Malware and removed a Trojan Virus, and thought the problem was fixed... I'm a Computer Technician myself, and am having a bit of trouble getting a hand on this... I've done several MalewareByte scans with fresh updates, Wi-Fi disabled, as well as AVG, Norton and McAfee scans and always turn up nothing, I have tried using the internet as though the virus wasn't there just by keeping the task manager open and every now and then clicking end process on Com Surr when it starts to replicate in an attempt to freeze my CPU... However I've started to realize, however to late I'm worried, that The Virus must indeed be removed , because it has blocked me from downloading help from the internet as well as caused the blue screen of death... I tried to follow your steps by downloading your tools, however my "Security Settings" Say that I am not allowed to download... I have been removing for years for fun Maleware and Trojan Viruses. But I have yet to meet a Foe such as this Com Surrogate until now, and I am certain that without help, I am certain to lose the WAR...

Thank You, J. Archer/NX-01

They call me TwinHeadedEagle around here, and I'll be working with you.
