Yes do run that as well! Basically just a system cleanup and removal of unnecessary files and a repair of corrupted files.
This can also work too! Ive never used the above program but just be careful on programs you download from the internet. Especially some anti-virus programs. Some are designed to infect your system with viruses and keep asking you to download more and more things which screw you over in the end (Trust me, my idiotic roommate did it :spit:lol! ). Youll basically just pack more spyware/adware/viruses into your system.
