Hijack.Trojan.Siredef.C ? UAC set too low


Recommended Posts

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll try to help your with your issue.
 
     
    
Before we start please read and note the following:

  • We're primarily oriented on malware removal here, so you must know that some issues just cannot be solved and you must be prepared for this. Some tools we use here will remove your browser search history, so backup your important links and all the files whose loss is unacceptable.
  • Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
  • Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time. Keep in mind that private life gets in the way too. Note that we may live in totally different time zones, what may cause some delays between answers.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • I volunteer to help you, so please, do not ask for help for your company/business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

:excl: I can't foresee everything, so if anything not covered in my instructions happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Three files attached.

 

The main symptom I detect is I cannot increase UAC:

 right-click run as administrator

 increase the bar

 clicking OK button does not save setting

 

This PC has a 2nd partition of Windows 7 that I have not used since the virus was discovered.

It also has Windows 10 preview that I have not used since the virus was discovered.

 

 

Scan_Log_0619.txt

Addition.txt

FRST.txt

Edit / Update to post above.

I changed 

ConsentPromptBehaviorAdmin to 1

ConsentPromptBehaviorUser to 0

 

Then I found the setting in Local Security Policy to always prompt for credentials.

I think that is the way it was configured before the virus.

icon_exclaim.gifMUST READ - general maintenance:

The Importance of Software Updating:

 

 
In order to stay protected it is very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.
 
Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.

Recommended additional software:

 
 
icon_arrow.gifCCleaner - to clean unneeded temporary files.
icon_arrow.gifMalwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gifMalwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gifMcShield - to prevent infections spread by removable media.
icon_arrow.gifUnchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gifAdblock - to surf the web without annoying ads! 
 
 

Post-cleanup procedures:

 

 
Download DelFix by Xplode and save it to your desktop.

  • Run the tool by right click on the 51a5ce45263de-delfix.png icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run.
  • The program will run for a few seconds and display a notepad report. You do not need to attach it.

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.
