Help! My computer sent me a notice or warning that I only had 1% free space left on my hard drive. I removed everything I possibly could and have used disc cleanup multiple times. I can't defragment because it needs 15% to run. I use this computer for home use, games, i-tunes, and several files in word but it just can't be full. I have a much older computer at work that has 10 years worth of Quick Books and it isn't even half full. I went to spybot and they had me click on some registry check and they found 3,380 errors and cleaned only 100 and then said I needed to buy a program to clean the rest. I use avg free and it isn't detecting a virus. I don't mind buying a program but I want to make sure I am not getting scammed. I am 61 and not all that computer savy. Can anyone advise me?
