Hello, my brother's laptop is currently so slow it's unusable, it's strange because the computer seems to only do work every couple of minutes. I downloaded malwarebytes and MSE but both of them fail to respond early into the scan, even in safe mode. I have some experience fixing infected computers potentially like this one but I haven't seen anything like this, and my brother claims that it just started happening one day. The only suspicious thing from what I can tell is his secondary-browser firefox has a funmoods homepage. I know this is vague but I don't have any leads, and my usual tools (mbam and mse) don't work. Thanks in advance.
