User Experiences & Case Studies

My company's network was experiencing unusual slowdowns and suspicious network activity. Traditional antivirus software wasn't detecting anything, so I turned to Process Hacker for deeper investigation.

Using Process Hacker's network monitoring feature, I discovered a process making connections to unknown IP addresses in Eastern Europe. The process had no digital signature and was running from a temporary folder - classic malware behavior.

The Solution

Process Hacker's detailed process properties showed me the full command line, parent process, and loaded DLLs. I was able to trace the malware's origin and identify all related processes. The ability to kill protected processes and remove them completely was invaluable.

Result: I successfully removed the malware, blocked the malicious network connections, and implemented better monitoring using Process Hacker. The system returned to normal performance, and we've been using Process Hacker for proactive monitoring ever since.

My development machine was running extremely slow, with constant disk thrashing and high CPU usage. Task Manager showed high overall usage but couldn't identify the specific culprit processes.

Process Hacker's detailed resource monitoring revealed that a background indexing service was consuming excessive disk I/O, and several Chrome processes had memory leaks accumulating over days of use.

The Solution

Using Process Hacker, I was able to:

• Identify memory-hungry processes with detailed memory breakdown
• Monitor disk I/O per process to find the indexing service issue
• Terminate unnecessary background processes safely
• Adjust process priorities for better performance

Result: System performance improved dramatically. CPU usage dropped from 80% to 15%, disk I/O normalized, and I gained valuable insights into resource usage patterns. Process Hacker is now my go-to tool for performance monitoring.
