I always like being able to recommend things to my gay bros that aren't exactly porn related, and one thing I fully recommend you take a look at to keep your computer clean and running as smooth as possible is CCleaner. This is a program that is free to use, offers some of the most advanced cleaning technology out there and basically just makes it so that you can tweak with a few simple things on your PC for the purposes of making it run a hell of a lot better.
It's simple to use and even if you don't know the first thing about computers, everything is explained to you in a simple, easy to understand fashion. CCleaner is regularly rated as the #1 tool in the computer safety community and comes chock full of useful features that will basically make it easier than ever for you to enjoy some top quality porn. Do yourself a favor and check it out - you won't be disappointed.
