I know that I don't know how it got on my computer and why it runs at almost 50% of the CPU usage constantly.
  Brenda  

that it takes up 85-95% of my CPU and that I didn't install it willingly...
  Mike  

it hogged my cpu on strart-up
  Dave  

This process is definently something that everyone should remove. It cannot be part of the Microsoft Anti-Spyware Beta because I had this process running even though I didnt have MAS Beta installed.
  Justin  

not a security problem but a terrible cpu and disk hog, shouldn't have been released in its present version

Microsoft spyware file. I have never had a problem with it eating up my resources, It is constantly running and it gets no where near using 80-90% of my resources, my computer runs perfectly normal and fine with it and it has never given me a problem.
  Jenny  

It's the microsoft anti spyware beta service file but 12,000 kb of running memory is just too dang much. I am dumping it asap.

slows down comp worse than any spyware or adware

Added by an unidentified WORM or TROJAN. Note - this is not related to Microsoft Antispyware which has a process bearing the same name which doesn’t appear as a startup

Would rather wait an extra second for my computer to load, and have some protection, than surf the net naked, people who dog it should just go out and buy a porno mag instead of downloading it from the net if they whinge about it that much, or get a decent computer.
   

It is a benign beta version of MS Windows AntiSpy Application, and it does consume sizable resourses temporarily, however. The jury is still out on its efficacy.
  siouxdonnm  

RTFM! It tells you right in the Anti-Spyware documentation: gcasDtServ.exe (provides access to SpyNet for reporting unknown applications) If it is hogging up resources on startup, its because its trying to establish a connection to spynet. Just turn off Connect to Spynet option in the settings!
  PDH  

i know that when i shutdown the spyware program my cpu went back to normal & when i started it again it went super slow & i have 2.6gig cpu.
  Ann  

There appear to be several versions of this file. One is related to Microsoft Antispyware, while the other is some sort of spyare/virus that uses up nearly 100percent of CPU in a rundll32.exe process in the process manager. The process will restart itself if stopped. HELP, removal needed!!
  Matt  

Hogs my entire computer; not worth much as anti-spyware.
   

I ran AdAware on my system and found no spyware was found. Then I uninstalled Microsoft Anit Virus Beta and re-ran AdAware and it found 65 pieces of spyware. Maybe Microsooft Beta nees some work. System is running much faster now and the gcasdtserv file is gone from my system. Maybe later the Beta will be better but for now not worth using due to problems.
  Glenn T  

Since installing Microsoft Anit Sypware Beta recent upgrade my system has been so slow I thought I was due for a major overhaul by format and reinstall all programs. Symptoms were numerous. Double click on icons to open and it took forever to open program. System would often freeze up and I had to press reset and go through reboot. When typing in Word Perfect documents I would have to slow down as the computer could not keep up with the key strokes made during normal typing. Perhaps this gcasktserv file is put in my Microsoft Antispyware Beta or maybe as some say it is a virus .
  Glenn T  

This hinders firefox strangely...
   

I recently downloaded updates for the MS Beta 1 antispyware, since then I have had probs with my computer crashing and rebooting itself specifically when I'm connected to the internet. There are no probs when I use my email though. The computer works fine offline, can do any task. Is this just a coincidence?

MS (Giant) antispy. Anothr MS resource hog.
   

Microsoft's Antispyware (BETA) program
  Samantha  

nearly locks the system up - have not checked to see if it is sending out data oer network yet, but doesn't look good
  David  

Not a virus even if showing as a startup file- Mine was, I removed it manually, and it broke MS AntiSpyware. So unless they did a really excellent job-doubtfull- it can be actual MS stuf and setup to run at startup. although it is the cause of many problems on my comp.
  ummduh  

just now when i was checking these articles out i noticed 6 icons in my tray when i passed over them they reduced to one. i have a amd 3200+ 64 system and it has almost consumed all of my resources it's a problem

If I kill the Microsoft Anitspareware (Tray Menu, right click) it disapears from the taskmanager. 100% Microsoft Anti Spyware
  Jojo  

Nothing to worry about, It's from Microsoft, a anti-spyware program thats also got alot of other useful tools. And it is definately NOT spyware (to those people who posted that it was). Though, it does offer good protection, it does consume quite an amount of resources.

Its microsoft anti spyware.... Uses a large amounts of resources
  John Laskey  

A friend gave this to me, and since I'd heard good things about it from a Ft. Worth CT columnist, I figured I'd give it a shot. Well, it's caught some things and has stopped AOL from forcing my web presets to AOL site, which is swell, but on the other hand, my system keeps locking up and programs keep crashing. At times, I can't open a new program unless I close everything else, and much of the time I can't even get the task manager to come up. It's not dangerous so much as just incredibly annoying. My advice? Stick to Lavasoft Ad-Aware and Spybot Search & Destroy. :/
  HamatoKameko  

Is part of MS Antispyware, but definitely causes problems. My laptop's CD drive became very slow and unreliable, for instance. Possibly is spyware, though, mimicking MSAS/GIANT product.
  Chris  

seems as MS AntiSpyware but consumes all of my resources...
  Segundo  

It is part of microsoft antispyware bu ton our new computers at school you cant even open notepad untill 2 min after startup because of it so i disabled it.

Affecting memory, w32.spybot was found in a directory of MS antispyware by symantec
   

Hangs at startup I need to press alt-ctrl-del and end the process to allow my software to run properly.
  Herman van Ree  

Slows system down hogs CPU process time. Will try Adaware as an alternate.
  Lou  

Slows Down Start Up
  Sean  

Seems like every time I restart my computer, it takes up every resource available, and whenever I end the process, it just comes right back and takes up all my processor capacity. Don't have a problem with gcasServ.exe though. Sometimes the little bugger just decides to act up and it gives me absolutely no benefits.
  brian  

locks world community grid program! annoying!
   

as i am working on a laptop. xp wouldnt complete is set-up properly. i also think it had some effect on explorer on start-up. after closing explorer and running it again then closing gcasdtserv.exe it seems to run better. ** to remove from start-up go to 'run', type MSCONFIG then untick the item in 'start-up'
  chris  

Not much uses a ton of resources really frustrating, slows everything down, doubles the time it takes adaware to scan

Microsoft antispyware a startup application (.exe) bearing the same is a piece of scumware
  Jeff  

This process consumes so much of the CPU that I cannot even type at my normal (slow) speed.
   

It runs at startup and uses up all the processor. When I terminate it, it starts again. I can't get rid of it. Help!
  Darrel  

It appears to be a resouce hog and I can find no use for it. It only became a problem after my MS anti-spyware beta expired.
  JerryinBKK  

It consumes all of my resources. gcasserv.exe is also running and consums almost as much resources. I doubt it's anything harmful but it's annoying.
  Interiority  

There are two versions of this file. One is the Microsoft AntiSpyware. The other is dumped by an unknown trojan/virus and is set to start on bootup.
  Joseph Grabko   (further information)

It is Microsoft's AntiSpyware Program by Giant, unless its in your Startup then its a file left by a worm or trojan. (Of course some people think Microsoft is a worm too)
  Tyler  

It seems to be a Windows Antispyware file. I have noticed on startup a system hang, especially on attempting to goto my computer properties. On stopping this service it ran immediately
  Jouleskeys  

I called Microsoft and they confirmed that there is a virus that eats all system resources with the same file name gcasdtserv.exe but there's doesn't run at start up! check this website for confirmation
  naterg   (further information)

i think people should check. I think that people should check because there IS looking like there is a variant of the file name that is actually a VIRUS... I am online but my computer is running near 100% CPU all the time
  P  

Microsoft Anti-Spyware, but takes a lot of memory, so it causes my computer to lock up from time to time. While I guess it should be a good thing, I survived without it before and would rather it not be hogging my resources.
  Sonja  

It is part of the Microsoft scanner but is a massive system hog. Espeacially on older systems. Kill the process if CPU activity hits full and uninstall if protected by another product. Wait for the full release and hope they iron out the resource hogging nature of the software and be carefull were you surf and what you download.
  Bob  

gcasDtServ.exe was running continiously , consuming more than 85% of my resources continiously after restart. Seems to be related to a malfunction of the 'Print Spooler'-service of Microsoft. Internet acces was disabled, two UDP ports were opened in my standard MS firewall advanced settings. My computer seemed to act as a gateway for UDP traffic. Killing proces gcasDtServ and restoring firewall settings, reinstalling AV and ZoneAlarm cured my PC totally. REMOVE gcasDtServ.exe from the Run(once) registry key in the registry and filesystem! Probably you should reinstall MS antispyware.

Its microsoft anti spyware.... but it consumes huge amounts of resources
   

Keeps Starcraft from installing and does eat up alot of resources at start up.
  fang  

It hogs resources, CPU running at over 90%... Could be a look-alike to MS spyware .exe, I don't know more yet...
  Cambaz  

Microsoft AntiSpyware, which has the side-effect of causing my mouse to hang every few seconds. Recommend disabling it when not actively surfing or downloading
  Shaun  

Its Microsoft Antispyware beta. It uses about 90% of CPU resources on startup and can almost bring an average powered PC to a standstill. HAving removed it and installed Adaware i found over 85 objects that Microsoft sPyweare didn't (or more accurately, that it had instaleld). In other words the Microsoft AntiSPyware Beta IS SPYWARE.
  Al Paton  

If this file takes all of your resources and pegs your processor at 100%, Your system is full of pests. Microsofts antispyware is now preventing your pest from contacting it's mother BOT and is continuing to try, therefore using all of your resources in it's attempt. If you disable this file and than all is well yopu have allowed your pest bot to complete it's mission. Rebuild your system period or live with someone controlling your system.

Microsoft written anti-spyware program. Useful but is a resourse hog when scanning files and on large system can take hours to complete scan. Despite this, it is worth the protection it affords.

a file named gcasdtserv.exe inserted itself in my startup files and is consuming all of my resources. the name is similar to the microsoft antispyware beta 1 exe file. It is very busy doing nothing except consuming resources. It did attempt to block attempts to obtain information on it through the internet. I killed it and all has been good.
