Cookie773

[REDACTED]

Hi,

My sons PC seems to have an issue with the above and is getting an Avast "threat blocked" popup repeating as follows:

Object: hxxp://hiopso90teraansuu.com/cookie773.exe
Infection: URL:Mal
Process: C:\Windows\System32\wscript.exe

Also every time I boot the system it starts with Windows Firewall and Security Centre disabled. I try and re-enable both but an error says they can't be started. He tells me he isn't using any other firewall.

I check both services and see they're disabled. I set them to auto then restart them and they're back but on the next reboot they're disabled again.

Through trial and error, I discovered if I kill a wscript.exe process the threat pop up stops.

However when I reboot the threat is redetected, the wscript process is back and the firewall and security centre are disabled so I'm back to square one.

I've run full scans and cleanups with Ccleaner, Avast, Malwarebytes, Bull Guard and tweaker.com but they don't find anything that helps it.

I attach the logs as requested and would be grateful for any help even if to stop him being so grumpy!

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.

Also, please tell me how your system is running now.

Hi,

I've done as requested, please see the attached log. The system now seems clear! The threat is no longer detected, script no longer running and Security Centre and Windows Firewall are now starting as normal.

We're very grateful, thank you for your assistance!

Regards,
Mike

Did you mean to remove the log file?


If everything else if fine for you (Avast is running / scanning with no warnings, etc.) then I will remove our tools and get you on your way ...


Clean up of Malware Removal Tools
Now that we are through using these tools, let's clean them off your system so that should you ever need to have malware removed again (we hope not) fresh, updated copies will be downloaded.

• Download Delfix from here to your desktop and double click it to start the program
  
• Ensure Remove disinfection tools is ticked
  Also tick:
  
• Activate UAC
• Create registry backup
• Purge system restore
• Reset system settings

• Click Run
  
• The program will run for a few moments and then notepad will open with a log. Note: Please save this log first before rebooting your system (if asked to); DelFix does not save the log as it is trying to remove all traces of our work on your system.  Please attach the log in your next reply.
  

You can delete any log files left on your desktop as these are no longer needed.

==Some Tools to consider to help keep your system safe ==

Unchecky is a small service that runs in the background to help keep those "extra toolbars" and tag along search engines from automatically installing.  By automatically directing you to a custom install with all the options unchecked, only what you manually choose and confirm gets installed.

CryptoPrevent is a free program that prevents CryptoLocker / ransomware from infecting your PC by locking down the OS so the malware can not get a grip on your system.  You can read the details about this program here.

Also, consider keeping MalwareBytes Antimalware in your arsenal of safe keeping programs. Use the free version (not the paid or trial version) and you won't have a problem with your antivirus scanner program. Keep it updated and run a scan with it once a week.

Lastly, if you use Firefox as your main web browser, consider adding the NoScript and uBlock Origin add-ons to the browser to block scripting hijacks and remove unwanted ads from the pages you view.

I'll leave this topic open for a few days so that if you have any questions you can come back here. Surf safe, my friend!!

Hi,

Yes I did as I didn't realise they were still required. Thanks for the clean-up instructions, I'll implement today.

Thank you again.
