I tired scanning with Malwarebytes, Superantispyware, Avast!, Eset, TdSSkiller, ADW Cleaner, AGV and didn't find anything. My computer's perfomance is very slow. Double clicking to open files on destop is either unresponsive or very slow. Loading sites on both the internet explorer and firefox is very slow. My computer tend to freeze alot. There are times I get DDOS on randomly. Can someone please help me fix this?
