In die Suchmaske gib "pavsrv51.exe" ein und Du siehst, dass sie zu Deiner Virensoftware gehört (aktive Tasks).
Security Task Manager Vers.17 zeigt, dass das Programm unbedingter Bestandteil von Panda Internet Security ist; ursprünglich stammt es aus Panda Platinum Antivirus - es ist der Viren-Scanner!Ich arbeite schon das 6.Jahr damit, das Prog. hat mir jetzt beim Defrag einen Buffer over run gemeldet. Man sollte sich beim Defrag o ä eben doch vom Internet trennen und die Antivirensoftware ausschalten.
It's frustrating when it runs for 1 hour 15 minutes taking 99% CPU and I have zero control of my computer!

Best practices for resolving pavsrv51 issues

A clean and tidy computer is the key requirement for avoiding problems with pavsrv51. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the pavsrv51.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
