about AVG Pctune up , I have used it and the only mentionable features are program deactivator and turbo mode , the rest ist not worth to mention , plus it takes up needles ram becuase it runs all the time and cannot be disabled. system mechanic registry cleaner VERY dangerous it can trash your system. just use wisecare365 and ccleaner ans you are covered!
