I recently found when using the physics stack exchange site that an unwanted program had installed itself on my Mac. This happened a few times before I managed to isolate the source. In some instances the program was called 'managerpages', and in others 'coveropen'. The behaviour of the program seemed to be the same in both sets of cases-it placed an icon on my dock and appeared as an extension in both safari and chrome. I deleted the program from application finder and removed the extensions.
However, I now notice a process named 'expertsearchmodule' consuming significant network resources, sending and receiving megabytes of data in a short time period. I have forced it to quit and it restarts.
Can anyone tell me if this is a bonafide process, or something fishy. If the latter, is there an easy way to expunge processes from my system? I have tried searching for the process on Google but have found very few references to it.
