Hello, I have the same problem, Malwarebytes will not restart I have followed this forum topic... I have ran Chameleon (all 13) ran Debug.bat file such as stated, but made no change (chameleon all 13 after as well) ran SVHOST file (sorry cant see forum post for exact name) Got report and alert that all scanner software should work now Ran Chameleon (all 13) but all still giving errors and will not run updatesMaybe this info is too old? Not sure. Im not sure when/where the problem came from, i detected that malwarebytes wouldnt start when trying to remove Browser Hijjack problems and wanted to do the step of scanning... then i saw that MB wouldnt start up. I was following the steps for removal of istart websearches (below) which i assume has to do with this. I know it was not that long ago i acutally opened MalwareBytes. http://malwaretips.com/blogs/istart-webssearches-com-removal/#malwarebytes Can you please assist? Thank you, Mag
