Thank you for giving me some information about Kaspersky. I really wanted to know if it is that good as it is rated on sites that review antiviruses and it held the 2nd position for the best 2014 antiviruses. I personally think that CCleaner, Malwarebytes and a good AV should be enough. Maybe a defragmenter as well ( I prefer O&O Defrag). Now, about Glary Utilities i think that it is going to slow your computer a bit, even though it will help get rid of junk, but other than that, it is just useless since CCleaner deletes useless files and junk on your computer.
Anyway, thank you for sharing with me your opinion.
