Hi!
I've seen similar posts and tried solving this on my own, but the solutions seem very specific and I can't get it to work.
It seems I managed to get infected with a bunch of malware. I tried installing malwarebytes, but installing it to the system drive got blocked with the infamous "Error 5". Installing it to a different drive worked, but starting the program didn't work, because "an administrator has blocked you from using this app".
I managed to get malwarebytes to work after I installed it with the chameleon tool. I also deleted the list of untrusted certificates that were blocking anti-virus software.
I had to run the chameleon tool normaly though, because booting to save mode with networking resulted in windows crashing (I don't know if that's relevant).
I could then run malwarebytes and remove a bunch of nasty stuff. I attached the log.
Afterwards Maywarebytes didn't find any new threats, but asked me to update. The update process however stopped with Error 5 after it removed the old installation and now I am without Malwarebytes once again. I attached the logs that the support tool collected as well.
It would be great, if you could help me get Malwarebytes working again.
