I was trying to help one of my friendes with cleaning a malware called Security Tool . I ended with reinstalling the OS for him.
I followed this solution in security mode and user mode. http://www.2-spyware.com/remove-security-tool.html
(I found the process with another noumber and was able to kill the process)
I tryed to edit registry entry too.
Tryes Windows defender (refused to start)
Tryed with Malwarebytes (full vertion). Malwarebytes refused to start.
My friend had a full vertion of McAfee Internet Security while the maleware infected him
My questinos are:
1. Why the Windows defender & Malwarebytes refused to start?
2. What could be the reson for McAfee was faild to deteced the malware?
3. Is the reinstallation of OS was the only way to clean these kind of malwares? If not, what are the options?
