strange space limitation on boot drive c:

hello dear administrators,
i am having a very strange problem. i, usually, clean boot drive c:, by
removing old files using option disk cleanup and cleaning old system files.
for example , i have space on boot drive = 4 Gb
used = 3.45 gb
free= 565 Mb
....
now, the problem is strange, when i cleaned disk(drive c:)
the free space becomes =700 MB as it should be.
but last time i used ICQ chat messenger and after it almost every day i saw
that my drive space is getting in use more and more
now free space on disk is almost 322 MB
i cleaned up drive c: , using disk clean up option, but it become
325 Mb instead of 565 as it should be, because i didn't install any program
for a long time , all old internet files are removed from the disk
i think there is any spyware or adware installed on my PC,
please guide me what to do with it and how to remove it ?
is there any link on microsoft.com to scan online and remove such softwares
from PC ?
please reply immediatly,
thank you,
your sincerely,
@rf@ni

It could be a lot of things, but the first thing I suspect is that someone
has compromised your computer and added a hidden FTP server on it. Try
clicking Start, Find, Files or Folders and seach for all files from today,
or the past few days, and look for anything suspicious. You could also try
searching for any file larger than 99,999KB and see what appears. The fport
or vision tools from www.foundstone.com/knowledge and a file change checker
like the free SIM from www.gfi.com or the more complicated Osiris might also
be useful here.

If this is XP, have you considered the space taken up by System Restore over
a period of time?

I suspect this is your system swap file going up and down.
Do a dir /ah on your c: to verify.
Also, do you have Windowsupdate running ? This will copy updates to your
HDD so that they're ready to install...

Cheers,

Tim
