Slow Computer

Hello,
I havn't visited this site since I bought my laptop 4 years ago
I have a extremely slow computer and first noticed the problem about
1 week ago. At first it started with glitching youtube videos. so I
ran an advertised program from this site called FixCleaner. After that
I noticed that, everything slowed down. I can barely type this post.
I also ran CC Cleaner with all the advanced settings checked. Please
help!
