This is an appeal for help from someone with limited experience – please be gentle with me and my lack of technical expertise!
So, here goes…
I am running Windows XP (SP3)
Last Sunday I noticed that my C Drive had filled up almost completely – less than 1GB space left.
I have no large files or photos on my PC; they are all stored on an EHD.
WinDirStat revealed the only large files to be a music file, which I removed as I was having a bit of a music ‘clean-up’ anyway, and some downloads from BBC iPlayer.
I then ran AVG, Malwarebytes, Superantispyware, C Cleaner, Kaspersky TDSSKiller, and the Windows Malicious Software Removal Tool.
This cleaned up some adware and 8 rootkits and gave me 127GB of disc space back.
I had hoped that I had rectified the issue, but since then my C Drive is slowly filling again (8GB since Sunday).
Yesterday when trying to do a google search Firefox presented me with a message stating that the google search page was using an invalid security certificate.
Also, and I’m not sure if this is relevant, but I’ll mention it just in case… when I tried to rerun TDSSKiller yesterday it would not load beyond 80%. I removed it and re-downloaded yet when I tried to run it from the new download I received a message telling me that an application was already running.
There is obviously something nasty (and invisible) which is still there, and I am now at a complete loss as to how to deal with it.
Any help would be greatly appreciated.
