Solved Suspected Svchost.exe virus

[Satya Arjun Patra]

Hello guys!
I want your help please.
My laptop has been infected with some kinds of virus, I don't know. All the antiviruses I'm trying to run aren't detecting any thing. That's why I have to enter in safe mode. HitmanPro detected one driver: ath8y.sys I'm not sure about the correct spelling. But still I found some temp files in the %temp% folder. There was a folder called hc_8433.tmp. I opened it and it had a subfolder named DumpFolder, it had another subfolder name hc_attk which had one .dmp file named svchost.exe34534.dmp. So I thought my laptop is infected with svchost.exe virus. I tried running most of the renowned free antivirus such as Malwarebytes Anti-malware, HitmanPro, 360 Total Security and Rogue killer. But most of them stopped after sometime automatically and didn't detect anything. Please help!!!!!!!

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
  
  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 for the repair.
• If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

Scan with Farbar Recovery Scan Tool

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

• Double-click to run it. When the tool opens click Yes to disclaimer.
• Press Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Here are the logs

What to do next??

 

[TwinHeadedEagle]

I do not recommend usage of IOBIT products, they have bad reputation, and are prone to create problems. That is why I suggest to uninstall:
- Advanced SystemCare 8
- Driver Booster
- Game Booster
- IObit Malware Fighter
- IObit Uninstaller
- Smart Defrag 2
- Surfing Protection

When you see a word "Booster", "Optimizer", "TuneUp" or similar it is often some kind of silly application. You cannot "boost" you system more than it actually is. Microsoft optimized Windows perfectly and they are constantly working on improvements, so these tools are just selling you nothing but "fog".

Only way to actually boost your system is to upgrade your hardware by adding SSD, more processor power or more ram memory.

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.

I'm sorry TwinHeaded Eagle but i accidentally deleted the farbar recovery scan tool yesterday, so can I just download it once again?

 

[Satya Arjun Patra]

I clicked the fix option. But my laptop restarted automatically and why it booted in normal mode? I had enabled the safe mode. I am attaching the log.

 

[TwinHeadedEagle]

Why would you go into Safe Mode?

 

[Satya Arjun Patra]

Because in normal mode none of the programs would run correctly all will crash.

 

[TwinHeadedEagle]

Please give me fresh FRST reports from normal mode:

Scan with Farbar Recovery Scan Tool

Please re-run Farbar Recovery Scan Tool to give me a fresh look at your system.

• 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).
• Make sure that Addition option is checked.
• Press Scan button and wait.
• The tool will produce two logfiles on your desktop: FRST.txt and Addition.txt.

Please include their content into your next reply.

Hello TwinHeadedEagle,
I have re-ran FRST and attaching the logs. I am having one other issue: Windows Firewall is disabled and is not getting turned on. What to do?? And I re-installed Qihoo 360 Total Security and it detected 3 malwares (I am attaching a screenshot). Please keep helping

 

[TwinHeadedEagle]

I don't know what to say. You have too low Ram memory for 64-bit operating system. There are a lot of errors and I suggest to install 32-bit operating system from the scratch.

 

[Satya Arjun Patra]

Then how it ran so smoothly few days back?

 

[Satya Arjun Patra]

Shall I try system restore?? or Reset the PC???

 

[TwinHeadedEagle]

Yes, try to Reset it.

 

[Satya Arjun Patra]

Hello TwinHeadedEagle,
I have restored my system to an earlier state. I'm uploading one 2 logs of FRST please check them.

 

[TwinHeadedEagle]

Your PC seems clean.

 

[Satya Arjun Patra]

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.

  icon and Run as administrator option.
• Make sure that these ones are checked:
  • Remove disinfection tools
