Ratingvsmon.exe ist integraler Bestandteil der Personal Firewall ZoneAlarm. Typische Probleme treten auf, wenn Filesharingprogramme wie EMule, KaZaA o.ä. benutzt werden. Hier schaukelt sich die Prozessorlast immer weiter hoch. Bis ZoneLabs eine funktionierende Version liefert, hilft nur ein Neustart der Firewall. Ralf

RatingIt takes alot of ram and cpu, it fails the panda unknown treaths service. Use sygate firwall. Good and stabel, or use pandas firewall. Not as good and let things trough, but should work for normal net surfing and gaming. If mp3, movie and program downloads from other computers on network, it is unsafe Viagra

RatingLook on the Zone Alarm site. There is a virus/worm (WORM_RBOT ) that exists in a file with the name vsmon.exe. But it sits in the system directory. the genuine file sits in the zonealarm directory. What I want to know is why the genuine one keeps grabbing more and more and more memory until a reboot is needed. Yes I do have the latest version.  link for more info Gary

RatingZonealarm security suite - can take up lots of cpu time when performing antivirus scan. I'd be worried if I didn't have a zonelabs product! h0me5k1n
RatingIf you have zone alarm, open up the control center, click the antivirus tab, then click antivirus options and set the time for sometime when it won't be annoying. If you don't have zonealarm, destroy it.
RatingWhen doing windows update..VsMon caused error in USER.EXE Perf.%age down. Have zonealarm,norton,spybot,and this too much?Disabled Zone and NOrton while scan/defragged..still only 65% performance. jaysgram
RatingYes it made my computer work as hell too. Wen't into ZoneAlarm, don't really expected to find anything but... ZoneAlarm was checking for Viruses!!! You can't really see when the program searches for viruses. That is the reason for that the program sometimes uses a lot of cpu. Badfellah
RatingWhile this element of ZoneAlarm is crucial to your internet security, it indeed does consume much cpu 'bandwidth' and can noticably slow down your computer. From what I understand, this program stores temporary data it has glanced over in its own cache. After much internet browsing with this process running it can buildup much stored memory. This is probobly what accounts for a majority of the 'slowing down' factor that many people have witnessed. To avoid this memory buildup, one can simply restart ZoneAlarm after few hours of internet usage, thus clearing out and resetting its memory buildup Michael Y

RatingSlows my computer down to a halt. Huge memory hog. I have ZA - but the virus scan is disabled - so that is not the issue. jooj
RatingFor five years I have had a memory problems could not understand why. I now have 1gig of ram in a P4 2.4cpu and I was still running low could not even play music while working on 20-60mb files in Photoshop my son was and he has a slower Pc at that. I run a clean Pc house to. Well today I found a file called vsmon.exe in windows task manager taking up 222.270k and my CPU was going nuts this time I did not re boot I put the file name in google and came to this site. I just re set zoon alarm and my CPU went back to normal. Carl..........

RatingZoneAlarm firewall file - very irritating and memory-consumable... I've got my computer on for a couple of days because I'm downloading stuff from eMule (not the illegal stuff of course ;) ) and now the vsmon.exe is using approximately 300MB of my RAM and up to 75% of my CPU...

RatingSchon 2 mal musste ich meinen PC Neustarten da nichts mehr lief bzw. sehr langsam, und den Prozess konnte ich auch nicht beenden. Danielle
RatingThe file is not dangerous. The sudden bursts of CPU usage is the schedule virusscan running. It doesn't give the user any hint as to what it's unless asked specifically :( . If you don't like it try disableing scheduled virusscans. Lithyum
RatingIt is a ZoneAlarm file. After 2 weeks of having it running without restart it started to use all my cpu. I shut it down and up and everithing goes fine again jicidre
RatingI restarted ZoneAlarm and a light went on in my navel. zardoz
RatingFrom the ZoneAlarm application. its ok, i mean, it doesnt bother me, but it uses a lot of RAM and CPU! :( max_00
RatingZoneAlarm's lookup table is small, and the code that parses through the lookup table is inefficient and has a small memory leak. Shut down ZoneAlarm Pro for 15 seconds and relaunch it once VSMON.exe is taking up more than half your memory so you can continue to operate. DRCray
Ratinghas memory leak in my Win2K systems. Keith
Ratinggehört zu ZoneAlarm, schluckt bei mir grad aber 388.000 K Jarod
RatingThis is a real shit this firewall ZoneAlarm... The best solution is to change with an other one Denis
RatingRuns when Zone Alarm performs a schedule scan, as a result it takes up CPU resources. To eliminate the "problem" simply set up the scheduled scan to run when you don't use the PC - i.e. the middle of the night. If you simply turn it off the PC will never get scanned!!! Jeff
RatingIt needs too many resources! anyway I found it's NOT related with ZA security threats. FabZ
RatingDisabling the automatic update function in zone alarm stopped the memory leakage in my machine Leo
Ratingseems to be on my machine with since i installed sp2 drains on cpu and hdd and memory. restarting ZAP will bring it under control
