I had a free version of Malwarebytes. Today I purchased a registration key for premium edition for 4 years. I managed to register it and it worked. When trying to update the version of malwarebytes the update was not working. So I followed the instructions and I tried the MB support utility and afterwards tried to performed the clean install. Afterwards I received Error no. 5 and malwarebytes vanished completely from the system. All methods of re-install have failed. I've run MBAR and the results are attached. I cleaned the infection, but still cannot install Malwarebytes.
How should I reinstall it and get rid of the malware?
