Re: Constant Antivirus popups/browser hijack: worm.win32.netsky

Hello Mark and welcome to TSF,

This will require more than one round to properly clean. Please stay with me until given the 'all clear' even if symptoms seemingly abate.


Please copy this page to Notepad and save to your desktop for reference as you will not have any browsers open while you are carrying out portions of these instructions.

It's IMPORTANT to carry out the instructions in the sequence listed below.

***************************************************

1. Download SmitfraudFix (by S!Ri) to your Desktop. Do not run it yet.


2. Download Combofix from any of the links below, and save it to your desktop.

Link 1
Link 2
Link 3

**Note: It is important that it is saved directly to your desktop**

--------------------------------------------------------------------

Close any open browsers.

--------------------------------------------------------------------

Disable Windows Defender as it may interfere with the fixes below:
  • Open Windows Defender.
  • Click on Tools, Options.
  • Scroll down and uncheck Turn on real-time protection (recommended).
  • After you uncheck this, click on the Save button and close Windows Defender.
--------------------------------------------------------------------

Please reboot your computer in Safe Mode by doing the following:
1) Restart your computer
2) After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
3) Instead of Windows loading as normal, a menu should appear
4) Use the up arrow key to highlight Safe Mode and press Enter.
5) Login with your usual account. Make sure to close any open browsers.

--------------------------------------------------------------------

Double-click on SmitfraudFix.exe to start the tool.
Select option #2 - Clean by typing 2 and press Enter.
Wait for the tool to complete and disk cleanup to finish.
You will be prompted : "Registry cleaning - Do you want to clean the registry?" answer Yes by typing Y and hit Enter.
The tool will also check if wininet.dll is infected. If a clean version is found, you will be prompted to replace wininet.dll. Answer Yes to the question "Replace infected file?" by typing Y and hit Enter.

A reboot may be needed to finish the cleaning process, if you computer does not restart automatically please do it yourself manually. (into Normal Mode.)

The tool will create a log named rapport.txt in the root of your drive, eg: Local Disk C: (C:\rapport.txt) or partition where your operating system is installed. Please post that log along with all others requested in your next reply.

--------------------------------------------------------------------

Double-click on SmitfraudFix.exe to start the tool.
Select option #3 - Delete Trusted zone by typing 3 and press Enter
Answer Yes to the question "Restore Trusted Zone ?" by typing Y and hit Enter.

Notes

1. If you use SpywareBlaster and/or IE-SPYAD, it will be necessary to re-install the protection both afford. For SpywareBlaster, run the program and re-protect all items. For IE-SPYAD, run the batch file and reinstall the protection.

--------------------------------------------------------------------

Double click on ComboFix.exe & follow the prompts.
  • When finished, it will produce a report for you.
  • Please post the C:\ComboFix.txt along with a new HijackThis log so we can continue cleaning the system.

Note:
Do not mouseclick combofix's window while it's running. That may cause it to stall


--------------------------------------------------------------------

Run a new scan with HijackThis and save the log.

--------------------------------------------------------------------

Please include the following in your next reply:

C:\rapport.txt
C:\ComboFix.txt
New HijackThis log
