External information from Paul Collins:
There are different files with the same name:

• "TrueVector" must run at start up. Even if you don't have ZoneAlarm or ZoneAlarm Pro run at start-up you do need this
• "Zone Alarm" definitely not required. Added by the RBOT.BO WORM! If this was the ZoneAlarm firewall the name column would be TrueVector

Important: Some malware camouflage themselves as vsmon.exe, particularly if they are located in c:\windows or c:\windows\system32 folder. Thus check the vsmon.exe process on your pc whether it is pest. We recommend Security Task Manager for verifying your computer's security. It is one of the Top Download Picks of 2005 of The Washington Post and PC World.

Somethimg changed my copy of vsmon such that the machine slowed down extremenly; it was "vibrating" the hard drive (another word for thrashing). stopping ZA stopped the problem. Reinstalling ZA seems to have stopped the problem from returning. I have used ZA for years on several computers and this is the first time it gave me a problem.

It always uses the most memory when my system is idle.

This is a file belonging to the ZoneAlarm firewall. It is NOT, absolutely NOT dagerous if you have ZoneAlarm installed, and is needed for your ZoneAlarm product to function correctly. Also, this DOES belong in your system folder if you have a ZA product installed.

vsmon keeps shutting down my AIM. Very annoying.

Belongs to Zone Alarm yes, but on my system it was using 30MB of ram - In my personal opinion it's a ram hog. Also if it crashes (which it does for me) you can no longer surf the web until you reboot. Great program, or at least it used to be.. Seems to have gone down hill, and fast.

secure but does eat a lot of CPU time!

If you have Zone Alarm Pro after V5.5.094 you are stuffed, click on my link to their forums. I just loaded this verision after suffering a 286 power emulation for just ages, then found this page and hunted on the zap forums. My machine flies now .

ZoneAlarm firewall. Just disable email scanning and most of your CPU-hog troubles shoud be over.

I have uninstalled ZoneAlarm but vsmon is still running. Disabled vsmon and I lost ALL internet access

right now its taking up 1.1 gigs of virtual ram and 124 megs of real ram... such a memory hog.. took my computer about 5 minutes to open a .exe file... if you have this restart your computer atleast everyday

If you have Zone Alarm installed, it's not a threat. It's doing what it's meant to do. If it's draining your CPU then you need to check your internet traffic. Simultaneously uploading, downloading, browsing, chatting etc. will cause it to be very unhappy with you. Check where it's running from. Test by shutting down your browser/downloader/chat temporarily.

Takes up about 23k constant, uses about 50% of my resouces when my computer is booting. This is also can b e a disgused virus.

This is the ZoneAlarm Service, no Danger. Even thought it Drains All of CPU and Most of Memory and PageFile. Restart the service again and it's back to normal, if not Try the Lastest Update it Solved All of the CPU and Memory problems.

Go to Zone Alarm Alerts & Logs and note the destination ip port (numbers after the colon). Go to Firewall Main Tab Internet Zone Security Custom. Add the port number to the incoming tcp and udp (click to add the number, then click the tick). Do the same for
