Windows 7 infected with svchost.exe
« on: June 02, 2015, 05:22:37 PM »
I have been getting blocked URL's from avast for about a month now.  It has been on and off and have tried to remove the virus but it keeps coming back. MBAM does not detect it and Avast reports nothing either. I have attached all logs required. Any help with this is greatly appreciated.

Hello,


Scan with ZOEK

Please download ZOEK by Smeenk and save it to your desktop (preferred version is the *.exe one)
Temporary disable your AntiVirus and AntiSpyware protection - instructions here.

  • Right-click on icon and select Run as Administrator to start the tool.
  • Wait patiently until the main console will appear, it may take a minute or two.
  • In the main box please paste in the following script:
Code: [Select]
createsrpoint;
autoclean;
emptyalltemp;
ipconfig /flushdns;b
  • Make sure that Scan All Users option is checked.
  • Push Run Script and wait patiently. The scan may take a couple of minutes.
  • When the scan completes, a zoek-results logfile should open in notepad.
  • If a reboot is needed, it will be opened after it. You may also find it at your main drive (usually C:\ drive)
Post its content into your next reply.

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.

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.
