Blocked Inbound connection to svchost.exe

[row]

Hi,

 

I'm worried I might have an infection because Malewarebytes has been blocking an inbound connection to svchost.exe from 60.173.12.42.  It has also been blocking an outbound connection to 60.173.12.42 from Chrome.

 

If this is abnormal please let me know what I should do.

 

I appreciate the help!

 

Requested Farbar logs are attached.

 

Thanks!

Ben

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

• Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
• Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
• Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
• Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
• Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
• Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
• Note that we may live in totally different time zones, what may cause some delays between answers.
• 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.

I can't foresee everything, so if anything unexpected happens, please stop and inform me!
There are no silly questions. Never be afraid to ask if in doubt!

Fix with Farbar Recovery Scan Tool
 

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

  (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 post it to your reply.

Very good. How is your PC now?

[row]

Since running the scans, I had several more inbound connections from 60.173.12.42 to svchost.exe and outbound Chrome connections to the same IP.

 

In the last 15 minutes the IP address has changed to 94.102.53.194, same inbound to svchost.exe and outbound Chrome.

Please re-run Malwarebytes' Anti-Malware.

• Click the History tab.
• Click Application Logs and double-click the newest Protection Log.
• At the bottom click Export and choose Text file.

Save the file to your desktop and include its content in your next reply.

Hi,

 

Attached is the Protection Log.

 

I've been trying to keep the internet off recently.  I've noticed svchost.exe has been writing to the disk a ton and using the network a lot.  I'm not sure how to figure out which specific process is the problem though.

 

Thanks for the help!

I found the service trwkwks that was running associated with the process svchost.  Google shows that it is likely malicious.  Not sure if that helps you at all.

Thanks again

[row]

I apologize, I meant to say trkwks.

I do not see this service as active. Where have you found it?

[row]

I found it running in the service tab of taskmanager.  It may be nothing.

How is your PC behaving now?

I'm having some blocked inbound connections again today.

Can you make a picture how these ads look like? PC seems pretty clean to me.

[row]

They are just notifications from malewarebytes about blocked connections.  I actually now think I only get them when using my school's wifi connection.  At home I'm behind a router and haven't gotten any notifications.  At least not recently.

[TwinHeadedEagle]

Can we then make this as Solved?

[row]

Yeah, I guess blocked inbound connections are nothing to worry about?  Thanks for the help.

Glad we could help.
