Solved SvcHost.exe Malware

[Cmdr Shepard]

Hi Team,

Ithink I've found my first virus and followed the guide to run ESET Poweliks, Malwarebytes anti-malware, HitmanPro, RougeKiller and Emsisoft Emergency Kit. I'm sure that the infection has been coming from SvcHost and it's still on my PC.

Thank you

Thank you TwinHeadedEagle. The help is really appreciated. I've followed your instructions with regards to the Adwcleaner and found that I had 2 logs Adwcleaner[S1] and Adwcleaner[C1]. I've uploaded them wasn't sure if you wanted them both together with the Zoek-results.

At the first reboot the SvcHost.exe tried to dial out, it didn't get a message so again after the second reboot.

I disable the antivirus but didn't disable the Malwarebytes before running Zoek. I didn't see it on the list on how to disable and I'm now thinking that I may of made a mistake in not disabling

I've also just had an attack that has been blocked by my antivirus.

Fix with Farbar Recovery Scan Tool

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

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
  
  icon and select
  
  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.

How is your PC behaving now?

 

[Cmdr Shepard]

Seems smoother than ever. I'm about to install Google Chrome as that's when the unwanted ads start popping up straight away.
I'll reply back as soon as it's done. Wish me luck.

 

[Cmdr Shepard]

I think it's working but I did get another Malwarebytes outbound block.
Should I give up on using Chrome?

Yes, we will delete used software.


Since there are no more problems, we can declare this PC clean

Now, we can proceed with post-cleanup procedures. Let's remove my tools and create a new, non infected restore point concurrently deleting old ones.


Step 1. - Creation of system restore point and tools removal.


Download DelFix by Xplode and save it to your desktop.

• Run the tool by right click on the
  
  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). I don't need it for review.

Tool deletes old system restore points and creates a fresh system restore point after cleaning.


Step 2. - Tips and tricks to keep your computer clean, safe and in a good shape.


Security tips - highly recommended reading:

• Simple and easy ways to keep your computer safe and secure on the Internet

Maintenance tips:

• Optimize Windows for better performance

Additional software that I personally use and install on all my clients devices:

• Zemana AntiMalware (paid version highly recommended) - to work as a supplement for your antivirus but with excellent remediation
• Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
• McShield - to prevent infections spread by removable media.
• Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
• CryptoPrevent - tool for protection against Cryptolocker and similar ransomware infections.
• Adblock - to surf the web without annoying ads!
• Qualys BrowserCheck - cloud service that scans your browsers and plugins to see if they’re all up-to-date.

My help is free for everybody.
