I have a Dell Dimension 520, with vista premium. Got it with 350Gb hard drive. Still under warrenty
3 weeks ago I started to lose 10-15 free GB from my OS C hard drive. Each day the free GB would go up and down (with no major changes in the operation of the computer.) It is now down to 15 free GB on the C drive. It was 190 three weeks ago. Dell says it must be a spyware or malware but they
can't find it.
When I open my C drive I see ArcDevice Info, unknown to me, but someone at my hospital said this may be constantly backing up your back-ups and causing the  free GB's to do down.
Anyone have  any thoughts on how to stop this vicious cycle of losing my free GB's from OS (C).

I'm not sure about your problem Mr. Lefleur, but I wanted to let you know
that you posted within a pretty old post.  You may want to repost in a new
thread so that it is more visible to people that might be able to help you
out.  The only reason I saw your post is that I am the originator of the
thread you posted in and got a notification that a reply had been posted in
my thread.  I hope someone helps you out!

Show quoteHide quoteDid you check into the backup state of affairs, then? If there could be some
backup software on it that you don't know about, you need to find out. I
couldn't find much out about ArcDevice from a quick check on the web. Is
this a file or a folder? How big is it, and does the size change?

Did anything else happen, start happening, or did you make any changes to
your system three weeks ago?

I'd recommend installing Agent Ransack
(http://www.mythicsoft.com/agentransack) and searching for new, large files.
I don't know about its compatibility with Vista, though - this is an XP
newsgroup, so you may also benefit from reposting your question in one of
the Vista groups. If you do, you should also start your own, new thread
there.

Or, for a more visual display of the sizes of your folders and files, try
SequoiaView freeware -
http://w3.win.tue.nl/nl/onderzoek/onderzoek_informatica/visualization/sequoiaview//.
The site says this *does* work under Vista.

Also, try a "chkdsk /r", or its Vista equivalent, on your C:\-drive, in case
the system is misreporting its free space.

Lastly, I'd suggest that you perform your own malware checks - Spybot,
SuperAntispyware, MalwareBytes and AdAware spring to mind, as well as your
current, up to date anti-virus program. (You *do* have one of those...?)

System font sizes - why don't they apply to all system text?
