ANY MALICIOUS PROGRAMS? PLEASE HELP.

I downloaded DetectX after receiving the chill-tab search engine which i can't remove somehow. YES I've tried deleting it off my extensions, but it's not even an extension. And when I DO remove it from my search engine and only use google, it downloads itself back on. This led me to believe that the virus is still in my computer. Programs that I think are malicious can't be deleted since it always pops up with Error -43 (Can't be deleted since one or more items can't be found) And most if not all of this files are .plist launch agents. I've attached screenshots of the DetectX report, please help me determine what is malware and how to get rid of chill-tab.
