With all the sync that is going on it is very hard to keep junk off. I use a combination of CCleaner, doing a browser clean of history, data and cookies. I use ccleaner to run a check on the registry and clean it though I am told it does very little to help but some help is better than none. Then I do a scan for malware etc... I manually uninstall any software I do not want. I do this for all my devices at least once a month. But then I am no longer programing and just use the system for my personal bookkeeping, emails and browsing. The more you use search engines (which you have no choice) the more crap that gets on even if you don't open any pages. It seems google and all the search engines want allow cookies when you don't even open a page. I have done searches and just read the results of the search without opening any page but the page that lists the search and had the browser cookie pop up come up and ask if you want to allow cookies from such and such. So, you do not even have to open a page to get a cookie or unwanted things. Security begins with you. Always remember anything you put on your computer can and will get out on the web if that computer is connected to the web. The best security you can have, is a system that is not connected to the web that you can transfer files from to a system that is connected but those transferred files are then no longer secure. I do not care how much security software you place on a computer there will be someone that will find a way in if they really want too.
