The file has been replaced by some new spy ware. Even though it is 720 KB, The size on disk is not right.. If you copy and replace it from another, non infected computer, it will work right again and not have the high CPU problem. Make sure you replace the one in windows\system32\dllcache too.  
It crowds the system wich may lead erratic operation

I often find it eating up CPU space with Task Manager, suggest manually blocking it with a firewall such as Zone Alarm with a promt (?) for future use - works for me.
When it is visible in the taskmanager/process, it hog the cpu power, slow down my computer and stop my winamp(i love my winamp...sob)

I know it is a pain and insult for Microsoft to put this in their OS

windows file, sometimes slows computer to a crawl. just end task it
This file is affected by malware and then opens at will, soaking up 99% of the cpu. Even after I put that file in a virus chest, it still opens on its own. A real pain in the butt.
If you go into the Control Panel and open Security Center, then close it, the service will stop hogging CPU time.
1) Do not let Uniblue ads frighten you into purchasing their product. 2) Problems with this service were supposedly addressed in SP2 (so says MS). 3) Can cause an unacceptable boot time and, more frequently, cause Windows to hang when opening Help and Support 4) DO check file sizes (above) to help verify it is Microsofts product (it needs to be) 5) Generally happens with XP Pro 6) Go to services and re-enable any services that depend on it and vice versa 7) Finally do NOT disable it; set it to MANUAL start up. It is necessary for Help and
its more of a hard drive hog than a cpu one
Hogs the cpu... had to kill it
HelpSVC.exe is located in folder C:\WINDOWS\PCHealth\HelpCtr\Binaries, its a system process, but when systems starts it rises the CPU & consume lots of memory which i think do not get free after we close that prosses with task manager. it has to be manully stoped ,as soon as system starts ,with the help of task manager.

To SHUT THIS OFF and put on Manual, Go to link below: Scroll down to "set Help and Support to manual or disable." and follow steps. It can be set back to automatic at any time.   (further information)
It is used to HELP you clean up your desktop if you have too many unused desktop icons. It's nothing to worry about, just close it and get on with your life.
its connecting to internet

helpsvc.exe is just a process that is used with help and support function in windows turning it off or blocking it disables help and support and nothing else

Since I have an old machine with only 256MB RAM and 750MHz, you can imagine that I open up the taskmanager quite often to check which process(es) is(are) heavy on CPU&memory. It may be mere coincidence, but I've noticed helpsvc.exe taking up 80+% for a minute only after I installed skype. I consider it a security risk,, since it can connect to networks , but rather than downloading strange tools, I'll try to blacklist it in the firewall and search help&support online manually if the onbord helpfiles don't suffice
Grinding my XP SP3 system to near uselessness. See it in task manager, cant find it in Windows explorer Search. I have attributes of Hidden and System enabled. Suspect a virus. Wish the sub directory was actually named in this article.
