gives alarm if spy/adware is installed
Hopes monitor system.

Great security file--gives up-to-date info on file
good system utility
Sensitive to changes, timely notification with details, free protection but at unspecified cost to user
WinPatrol's top feature is how it monitors and allows you to review the programs that automatically launch when you start WindowWinPatrol monitors and displays more locations then your typical programs of its type including MSConfig.s.
it will not let a program install itself to automatically start without your ok

Good Monitoring of system changes
I downloaded it and got the conficker worm.
Have been running it for 3 yrs in conjunction with Zonealarm, AVG, Spysweeper & recently with PC Tools Threatfire. None of these programs have highlighted Winpatrol as a threat.I have recently installed Prevex 3.0 & this product has called it a worm, but I don't agree & have notified them.
I also used WinPatrol. Now I’m using AnVir Task Manager, it’s the best solution for my PC. It manages startup programs and active processes, removes spyware. It shows full information about each process including command line, inbound and outbound traffic, disk load, tray icon, performance graph, internet connections

It is actually a good monitoring and security application I've been using it for years. But sometimes hang-up when catch some new threats or program trying to run or install. BUT BE CAREFUL! I tried to uninstall it and got into a big problems...any application or exe cannot be open, even the OPEN context menu when you right click the mouse is not showing up. Even System Restore cannot be open. Any Windows system files cannot must have deleted also some Windows System a complete messed.I have no choice than to re-format my PC. Even anything on the external drive or USB application cannot run.

Best practices for resolving WinPatrol issues

A clean and tidy computer is the key requirement for avoiding problems with WinPatrol. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
