If we use Windows, we must have an antivirus on the computer. In Windows 10 we have included Microsoft’s antivirus with Windows.
Defender, but its protection is not up to par with other competitors.
And if we talk about performance, the figures are even more worrying.
Windows Defender Is The Antivirus That Slows Down Your Computer The Most
This has been demonstrated by AV-Comparatives in a series of tests where they have verified the impact on the performance of 18 antiviruses on the same computer: a Lenovo G50 with an Intel Core i3-4005U, 4 GB of RAM, a hard disk, and the Windows 10 Fall Creators Update.
Therefore, we are dealing with a low-end computer, and the user experience could change on a high-end computer.
To check performance, tasks such as copying files, installing and removing programs, opening programs, downloading files, visiting web pages, and performance tests with PC Mark 10 were performed.
It was sought to minimize the presence of other programs that could interfere with the results.
After trying each antivirus, the initial image was reinstalled and the computer was restarted six times.
In addition, each test was done several times and the median of the tests was chosen to avoid disparate results.
This yields a series of rather curious scores. The first is that Windows Defender is the antivirus that most affects computer performance ( that’s why it can be disabled ), followed closely by Quick Heal and Trend Micro.
Where Windows 10 performance affected the most is when copying files and installing applications, while where it impacted the least is when downloading files.

Avoid Using Trend Micro, Quick Heal, And Windows Defender You Don’t Want Them To Affect Your Performance
On the good side, we have the antiviruses that usually get the best figures in this regard in the AV-Test list.
The antivirus that least affects performance is K7, followed by ESET, Avast, AVG, Bitdefender, and McAfee. All of them manage to stay with a fairly low impact.
Most antiviruses do not have any impact on performance when we browse the Internet.
However, where slowdowns were seen the most was when launching a program for the first time after installing it with antivirus from Tencent, Trend Micro, Emsisoft, and VIPRE.
This impact is usually less the more times the program is opened since optimizations are made and learning about how the program works.
Therefore, the recommended products with the Advanced+ award with 3 stars are K7 antivirus, ESET, Avast, AVG, Bitdefender, McAfee, Kaspersky Lab, and Tencent.
Those that had a star, and therefore the standard award, are Trend Micro, Quick Heal, and Windows Defender, which are the ones you should avoid if you want to have the best protection and the least possible impact on your PC’s performance.
