Yes. No matter what kind of device your computer uses for its primary data storage, if that storage is full enough, it will bog down your computer’s performance. In extreme cases, your computer will slow down to a point that makes it feel completely unusable. Fortunately, there are remedies to the problem.

Sophos can slow computers down, but that won’t always be the case. As a security software suite, it performs a lot of tasks, and if it is working hard on a computer that doesn’t have resources to spare, you’ll experience slowness. If Sophos doesn’t overtax your system, then you’ll never experience a problem.

Trend Micro certainly can slow down a computer, but that won’t always be the case. The performance impacts depend on how powerful your computer is, what services Trend Micro is running and how many security threats are being detected. You can customize your experience for better performance if needed.

Usually, Rainmeter is not going to slow down your computer by any amount that you are likely to notice. The software has been around for more than a decade, and it is designed to work across a wide range of builds. There are specific circumstances where you might want to turn it off, but most computers are fine.
