Agree. This is free and great. I've been using it for over a year. I also use the free CCleaner (remember to also empty your "downloads" file if needed and to run the disk cleanup as you must compress files from time to time or your computer will run slowly. I also have superantispyware and malwarebyte's anti-malware installed. All four FREE programs keep my computers running without a problem.
