I have been using spybot s and d for several months. Tonight Windows defender popped up and said I had trojandownload threat. I removed it. I went to run my spybot and I get a pop up that says windows cannot access the specified path or file and that I dont have permissiion to run it. I used it yesterday. Also yahoo is my browser and it automatically goes to google and none of the normal stuff is coming up when I search. What should I do?

* When MBA-M finishes, Notepad will open with the log. Please save it where you can find it easily. The log can also be opened by going to Start > All Programs > Malwarebytes' Anti-Malware > Logs > log-date.txt.

Reboot the computer.
Please Run the ESET Online Scanner and attach the ScanLog with your post for assistance.
