SUMMARY="DetectX is, rather, a lightweight, on-demand dedicated search and troubleshooting tool that can identify malware, adware, keyloggers, potentially unwanted apps and potentially destabilising apps on a mac. It can also help you (or us, if you consult us), to identify unknown and novel threats through its Profiler and History functions."
