Zonealarm firewall asks whether to allow Application Host Service to connect to internet or not. Application Host Service is trying to access the Internet. I installed Panda Antivirus.
Its hogging my CPU.

This application is consuming 96% of a CPU HP ML350 server with 10 GB of memory.
gehört zu Panda Security Protection
runs about 70 threads and 25% CPU when otherwise doing nothing
It's fine. It can take up some Cpu especially right after Start-Up. It is essential for all Panda Cloud products. So don't consider deleting if u use Panda Cloud products. 4 Stars if u use Panda.

Es hat meinen CPU nahezu vollständig verschlungen. Nach der Deinstallation lief mein PC wieder um Längen besser. Ich vermeide in Zukunft PSANHost.exe und alles was damit zu tun hat. Habe keine guten Erfahrungen damit gemacht.

Best practices for resolving PSANHost issues

A clean and tidy computer is the key requirement for avoiding problems with PSANHost. 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.
