It was too much for what I had to do on the computer. Instead, I used Norton Internet Security, and it works just fine and keeps out what I need to keep out. To maintain my computer, I use CCleaner. They have an email address of the same name ending in com. They have a free version as well as a professional one. Even though I set my cleaner to run on starting up the computer, I also run it once a week, along with the defragmenter that comes with windows, and I also run the Norton, although it too runs on its own whenever I'm idle. Hope this helps!!!
