I have an Acer 1641 WLMI model laptop computer running Windows XP Pro Home Edition operating system. I am currently using AVG 7.5 anti virus and spyware, plus a route kit free version and I am also using Spybot.

My problem is that free space on my C Drive is disappearing at around 200 Mb per day. I have deleted many Programs via the control panel to create extra space, I have deleted all restore points except for the last one, I have recently defragmented the C: Drive. I perform a disk clean up every evening to remove temporary internet files, I have also cleared temporary files in the path C:/Windows/temporary, I created an extra Gigabit of free space on the Hard Drive, but every time that I create some space it disappears quickly.

It seems to me that something is replicating itself but still passing my systems security checks. Is there a dos command that can be used to trace any file that is growing or replicating itself? Has anyone experienced something similar and do you have any solutions?

The first thing I would do is run a rootkit scan.

I highly recommend the Sophos anti-rootkit scan tool.

They make you register for the download, but it's free, and you can always put random info in there.

Thanks for taking some time on this problem Rob 1, I have tried AVG rootkit which found some problems. I have AVG 7.5 anti virus and spyware running and updating regularly, spybot is also in use, but still have this problem, thanks anyway Rob

If AVG found some rootkit problems, then you seriously should consider a fresh reformat/reinstall.
