Your system is severly infected. Problem with these infections nowadays is, it causes a lot of damage. Even if we clean the malware off your system, I can't guarantee that your system will be clean afterwards, because these infections/bundles leave a lot of leftovers behind that most scanners won't even recognise and logs won't show.
Also, I can't promise you we can repair all the damage it caused... Even after cleaning the malware, you can still get errors afterwards because of the damage. Solving these is not always possible since it will be searching for a needle in a haystack to find the right cause and solution.
So, we can try to clean this up and do what we can, but keep in mind that we can't solve ALL problems this malware already caused.
In light of this it would be wise for you to back up any files and folders that you don't want to lose before we start. Reason I am telling this is because when a system is so terribly infected and we try to clean this up manually, the damage that is already present may interfere with our removal attempts.
Please try this version of malwarebytes: Click the link here
Save it on your desktop
. You'll see it will have a random name, and will look similar like this:
Doubleclick on it, so it will extract the files and will start Malwarebytes automatically.
In case the installer (random named file) won't run either, rename it to EXPLORER.EXE and try again.
When Malwarebytes opens, click the "Update" tab FIRST and select to check for updates in order to get the latest updates.
In case Malwarebytes doesn't open, search for the folder mbam-installer
on your desktop, open it and doubleclick the file winlogon.exe which will be present in there. This should launch Malwarebytes.
Then perform a scan and let it remove what it found. Reboot afterwards (important).
After reboot, post the malwarebytes log together with a new HijackThislog.
In case you're having problems with above instructions, let me know.
