What the two above said ^^^... Plus:
I would reccommend you to remove these "commonly targeted" items if you have no use to them:
-Shockwave Flash
-Adobe Reader (Foxit Reader is an alternative)
-Oracle Java
-Microsoft Office App (If you like a word-specific feature, etc., don't panic, but Kingsoft Office and OpenOffice are great alternatives)
-Skype (I install when I use and uninstall/disable when I don't)
Important Note: Disable AdGuard Easy List filter in Chrome, it uses 50+ MB more memory with EasyList/ Fanboy's Annoyance List, etc. Stick with the regular English, Spanish, etc., lists.
