Computer help forum: hard disk constantly filling up

Does it error that you've reached maximum capacity?

Try starting it in safemode and downloading a free antivirus program (if you don't have one already). The top one that c|net recommends is http://download.cnet.com/Avast-Free-Antivirus/3000-2239_4-10019223.html - it says it will take up 92MB if you still have the space

Once the scan is done let us know the results - otherwise it could just be that your hard disk is terminally ill

That would be my next best guess

Unfortunately, hard drives do die - often when they're very young, or very old - How old/young is your machine?

If it's a crafty virus/malware you might have to, like R. Profitt says, wipe it just to be sure - Fortunately (or is it unfortunately?) you have nothing to lose if you have a dwindling hard drive:

Case A) You leave it, and your hard drive implodes on itself

Case B) You wipe it, isn't a hardware problem, you have a fresh hard drive to work with

Just make sure to get your important stuff off the machine first!

Sounds like a good direction - you're on the lucky end of things though! Hard drives have grown to be pretty cheap since 2007

And those apps which will pass all scans can nab a chunk of diskspace almost unannounced. I've lost count of issues torrent users bring to me.
