Zoek may take some time to complete, this is normal. Once finished the program will reboot your machine, if not then please do so manually.
Post the log created by Zoek you may find it on the C: drive.
I suggest that you download CCLEANER then run it, hit the option's button then settings,put a tick next to Run Ccleaner when the computer starts.
Also when in options go to advanced tab and put a tick next to close program after cleaning.
This will automate the temporary file removal on your machine and keep it speedy.
Disable all of the start ups on the machine except your antivirus.
To disable hit the tools button then the start up button,then disable.
Now please in your next reply please give me the Zoek log and a new minitoolbox log we are not done yet I do not want to give you too much at once to do.
