Hard Drive Question!?

I've been noticing over the last couple of weeks that the space on my hard drive is slowing decreasing by 0.1 Gb nearly everyday. I haven't installed anything lately and I move all the pictures, videos, and music I download onto an external hard drive that I bought specifically for that purpose because I have a relatively small internal hard drive. I run a spyware/adware/virus check once a week and nothing has shown up. My question is...Do I have programs updating that aren't telling me or do I have a more serious problem??? Thanks for all your help!!!!

Run disk cleanup in system tools. Cleans junk.

Make sure all boxes are ticked in cleanup.

And the spyware/adware/anti virus updates run daily. They add a little. But disk cleanup will keep it clean.

Right click my computer then system restore and move the slider to 5% or even 3%.

It will remove the oldest restore point when making a new one.

System restore uses the amount of space you have allocated in system restore setup

What you are seeing is System Restore gobbling up your hard drive space. You know it keeps making back up restore points that eat up hard drive space. A useful Windows utility? - at times but as you can see it will cause problems as well - more frequent defrags of the hard drive - after cleaning spyware - System Restore will often restore the spyware with a reboot. Personally - I shut it off on my computer. Right click My Computer - properties - System Restore tab - uncheck.
Try searching for a utility called CCleaner. This cleans out all the unwanted files easily and will restore your drive space.
Cleanup temporary internet files/system restore files.

Get ccleaner
The best solution I found was to use a program called ccleaner.

This will let you see many hidden files, but you need to be a little careful about what you delete - it will do no harm, but you can delete everything from your hibernation file, chkdsk fragments, and even history of windows downloads and installer files.

It is free, and will do a lovely job of tidying up your registry. Something else - remember to leave your system to do a complete defrag when you finished cleaning it up. I started with a 320GB harddrive a few months ago, and wow - not too long after that I had a shock, and ccleaner safely removed a ton of rubbish.
