With that said, if you are using some other antivirus, chances are, you might see an impact on system speed, but it is temporary.

Here are a few things you need to know about antivirus and how to speed up computers.

Why Do We Criticize Antivirus for Slowing Down Things?

It is not that only security applications use processing power. All applications use it. But with an antivirus, CPU usage can be constant, as it protects the system in real time and scans every program. Usually, this happens when a new app is installed and a file is downloaded from the web. When this happens, the antivirus compares the network drive with the malware signatures and behaviors database. These security scans need power, so you experience a dip that is not last.

However, if you see your device slowing down that it becomes unusable, it is unlikely that antivirus alone will be behind it. There are other reasons, too, before making changes to the security suite.

Other Factors Responsible for Slow PC Performance.

Most people blame newly installed software without knowing what is causing speed issues. Therefore, before uninstalling or switching antivirus, it is suggested to know the underlying factor.

Check the following before concluding that antivirus is the reason for slow speed.

1. Almost Full Hard Drive

When identifying the cause of slow system speed, your hard drive is the first place to look. If there’s not enough space on the disk, or the disk is fragmented, or has too many junk files, it will slow down the system. Similarly, old hard drives can also reduce functionality, resulting in speed problems.

2. Malware

Malware, virus, spyware, and adware are the number one cause of computer slowdown. The malware can still slip through even if you think you are very cautious when downloading a file or working online. In such cases, instead of uninstalling the antivirus, try using one. This will help make the PC faster. But don’t get fooled by free antivirus as they are usually packed with malware hidden in plain sight.

Therefore, go with the best antivirus for PC like Systweak Antivirus.
