inetinfo.exe using 100% cpu

[yaugin]

Occasionally my system becomes unresponsive and the task manager shows
inetinfo.exe using close to 100% cpu. I looked it up and it appears to
be a system process for IIS. The thing is, I'm on a plain old XP
desktop computer that isn't running IIS. Should this process be
present, because if not I suspect it might be a trojan or worm. If it
is legit, how to make it stop hogging the CPU?

Hello,

Are you using Windows XP Professional ? Check to see if you have IIS installed or not. Go to Control
Panel > Add/Remove Programs > Add/Remove Windows Components. Scroll down the list and see if there
is a check next to "Internet Information Services". To un-install IIS, just uncheck the checkbox.

When all else fails, HijackThis v1.99.1
(http://aumha.org/downloads/hijackthis.zip) is the preferred tool to use.
It will help you to both identify and remove any hijackware/spyware. **Post

If the procedures look too complex - and there is no shame in admitting this
isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA) computer repair shop.
