Threat Detected appearing all the time - svchost.exe
« on: June 12, 2015, 10:11:37 PM »
I'm getting VERY frequent pop-up boxes reporting that a threat has been detected.
It is centred on the svchost.exe with ortiguard, any-Chicago

Attached are the basic scan log files, I will perform a Zoek scan now.

many thanks

I used one of your scripts, but changed the user to MYNAME

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)

Cheers :)

• The following will implement some post-cleanup procedures:

=> Please download DelFix by Xplode to your Desktop.

Run the tool and check the following boxes below;
Remove disinfection tools
Create registry backup
Purge System Restore
Click Run button and wait a few seconds for the programme completes his work.
At this point all the tools we used here should be gone. Tool will create an report for you (C:\DelFix.txt)

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.
