Each time I start up the computer again, it feels like it runs slower than the last time I used it. I already tried updating the software, but that didn’t fix the problem.
Sometimes the computer can run slower when there are unnecessary apps that run in the background when you start it up. If you’ve already tried updating your software, I would recommend downloading and running a spyware program. This will help if you have a virus that is causing your computer to slow down. If this doesn’t help, feel free to check out the troubleshooting guide here.
When computers slow down its usually from spyware or malware Run a trusted anti spyware program like “Spybot search and destroy” or Malwarebytes Hope this helps
I find that using IOBIT’s Advance System Care (Free version http://www.iobit.com/en/index.php ) fixes the problem and helps keep it clean, as well as it has a very great device driver updater, un-installer and, malware protection too. If you decide to buy it, it’s currently on sale, I use the Pro-Version.
