I have become more conscious about computer security and the importance of being aware of what is running on my laptop. I suspect that my MBP might be infected with malware as there have been empty black boxes slowly coming up on the right side of my browser when I visit various sites. The sites I visit when this occurs are not the same and this happens whether I use google chrome or firefox (and yes, I do have adblock). Sometimes I notice odd behaviours like all of the windows open on my laptop suddenly moving slowly to different corners of my screen, minimizing as they do so. When this happens, I'm usually in the middle of typing something out or I am not even doing anything. After a few seconds of clicking, it goes back to normal. At times, my mouse would not move. Is it possible that my laptop may be infected? If so, by what and how can I remove it? Also, I have quite a few processes running when I check my activity monitor. One process that is continuously running and that attempts sometimes to connect to the internet according to my firewall software is usbmuxd although I don't have an iPhone or i-anything nor have I ever connected one to my laptop. Whenever I quit or force quit the process on the activity monitor, it never fails to return within seconds. Also, there are many processes running on my activity monitor. Could any of these possibly be something malicious? For a better idea of what processes are running on my system, I've included screenshots: http://imgur.com/0NRZ0vH http://imgur.com/CTjIGCb http://imgur.com/XHtcBR8 http://imgur.com/wcBjoz4 http://imgur.com/hX5YhYB (Blacked out user is the main account on my MBP, the name is very unique and I'd like to remain anonymous hence the blacking out.) Thank you in advance for your responses.
