Hallo,

please, can you help me?

 

svchost.exe is connected (connection is established when computer starts) to particular address, for me fully unknow.

 

This is a log file:

 

20:10:54    SVCHOST.EXE    OUT    TCP    hefra.mobilatak.net    80    Generic Host Process HTTP connection    0    0    SVCHOST.EXE: 3720
20:10:54    SVCHOST.EXE    OUT    TCP    hefra-ap1.mobilatak.net    80    Generic Host Process HTTP connection    0    0    SVCHOST.EXE: 3720
 

I use NOD32 ESET antivirus, Outpost Firewall, I scanned my comuper with Bitdefender, Malwarebtes Anti-Malware. Nothing - computer should be clean.

 

Can anyone advise me, please, how to find out what connects via svchost.exe to this address? Or how can I stop it?

 

Thank you

 

Radovan

Thanks for the logs, continue as follows:

 

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Run FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Hello,
mobilatak.net the internet provider and provides thousands of pages. My provider it is not. My provider does not use any mobilatak.net services (I asked him). I asked mobilatak.net admin - and admin does not know why my PC connects to the mobilatak.net server. I have not heard about mobilatak.net two weeks ago. I quote: I do not find anything bad related to that service? This is right. But it is for me unidentified service. Service, who do not want.

Thanks for the update Radovan, if no remaining issues or concerns run the following to clean up...

 

Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:



  •    
  • Remove disinfection tools
       
  • Purge System Restore <--- this will remove all previous restore points and create a fresh point relative to system status at present.
       
  • Reset system settings



Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…
