Fake security alert for win32/caphaw - not found by any scanner

Recommended Posts

I have a pop up box that says Security Alert and below it says that Malware:win32/caphaw has been found.  I know that there is no caphaw infection and the popup itself is the malware trying to get me to call the 800 number and give my credit card.  When the popup occurs, there is a process in task manager called alert.exe.  I can end the process and the popup goes away only to come back minutes later.  I have tied scanning with Malwarebytes, TrendMicro Internet Security, Viper, Microsoft Malicious Software remover, rkill and TDSSKiller from Kaspersky. I have done each one in safe mode as well as regular mode.  There is no infection of any kind found by any scanner.  Is there something I am missing or is this malware so new it is not on anyone's definition table yet?  Please Help!

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
    
 
    
Before we start please read and note the following:

  • 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.
  • 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 Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
  • Note that we may live in totally different time zones, what may cause some delays between answers.
  • Do not ask for help for your 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 unexpected happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Very good :)

 
 
Let's perform our final scan:
 
 
 
 
51a5bf3d99e8a-ComboFixlogo16.png Scan with ComboFix
 
This is a very powerful tool that should be used only if advised by Malware Analyst.
Do not run ComboFix on your own!

 
Referring to this instruction, please download ComboFix by sUBs and save it to your desktop.
Temporary disable your AntiVirus and AntiSpyware protection - instructions here.

  • Right-click on 51a5bf3d99e8a-ComboFixlogo16.png icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • Accept the disclaimer and agree if prompted to install Recovery Console.
  • Do not take any actions while ComboFix goes through your System - it may cause it to stall!
  • This scan may take some time!
  • When finished - it will display a logfile (located also on your main drive, usually C:\ComboFix.txt).

Include that log in your next reply.
icon_idea.gif If you'll encounter any issues with internet connection after running ComboFix, please visit this link.
icon_idea.gif If an error about operation on the key marked for deletion will appear after running the tool, please reboot your machine.

I believe this situation has finally been resolved. Thank you for all your help. One question though, why would no scanner find and kill this thing automatically? This is the first time this has ever happened where I had to go through so many steps to kill something off.

It is not that simple. There are sometimes multiple layers of protection malware uses to hide and defend its presence. Sometimes ordinary programs aren't enough :)

 

 

 

Below you will find my thoughts about securing your machine. Go ahead through it, you will benefit from some useful advice about safe computing.

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.gifTFC - 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.gifCryptoPrevent - to secure yourself from very severe CryptoLocker infection.

icon_arrow.gifUnchecky - to prevent from installing additional foistware, implemented in legitimate installations.

icon_arrow.gifFiheHippo.com Update Checker - to keep your programs up-to-date.

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. 

 

 

 

My help is free for everybody.
