Tip from the PitCrew

Every process running on your computer takes up CPU cycles and valuable memory. For optimal PC performance and resource utilization, you should be aware of every process on your computer. PC Pitstop designed this process library to help you know which processes are worthwhile and others that slow system performance.

Furthermore, perhaps the quickest and most straight forward method to detect malware is through a running process analysis.
