Computer is slow

If your computer is slower than normal, it might be infected by malware. First run a malware scan. I can recommend using Malwarebytes.

Your hard disk might be running out of space as well, you can often fix the problem simply by cleaning the hard disk of unwanted files. You can also install a firewall, anti-virus and anti-spyware tools, and schedule regular registry scans. External hard drives are great storage solutions for overtaxed CPU’s, and will help your computer run faster.
