My computer is infected with Malware Defense. I just noticed this weekend so it had to have happened within the past few days. I installed MBAM, had problems with the install file not working, I diligently read through these forums and the renaming worked for that. I was able to install MBAM. I have not, at this point been able to get MBAM to ever run for me though! I tried renaming it and it does nothing. It did it in and out of safe mode. I did it with and without internet connectivity. I am stuck. This forum has helped many people so I am keeping my fingers crossed... Thanks in advance!
