Hard disk free space is lessening and lessening?spyware removal

If nothing you found here is working, try doing this. Sorry about your luck! Did you try system restore? If you want to go back to when you had your comp almost new, you must first save any important files to a CD or floppy.... in Windows XP......go to start, all programs, accessories ( second column ), system tools, system restore ( bottom, right column )

close all other windows, before using this. Then Restore to an earlier date. After your done, restart your ( comp. ) windows. Good luck!

Hard disk free space is lessening and lessening?virus protection software

Well, at least you know what to do. I don't really understand why it always lessens every reboot, unless you always install a new software in your pc everytime. Try going into safe mode and run ccleaner there, it should help. Try going into C:\Documents and Settings\(Your name)\Local Settings\Temp and delete the files there, and of course disk cleanup which I assume you should have done it already. It shouldn't post any problems.
