Spybot/Malwarebytes won't run

[sdar7]

First time posting here. I have caught a virus that seems to be messing with my ability to run spybot and malwarebytes. When I click on them, or try to open them with the run command I just get an hourglass for about a second and then nothing. Also, often mozilla will not open either, it will pop up for a second then go away. My computer does sometimes randomly try to open IE and asks me to prompt it as my default browser. Also, I downloaded combofix but cannot run or install it, the same thing happens as before, just a quick hourglass. I tried to update HJT and the same thing happens. Any suggestions? My hjt log is as follows. Any help would be appreciated.

Problem solved. I renamed the malwarebytes executable file and was able to run it and then spybot. Everything seems to be working fine now.

The HJT version you posted with is very old.
