Antivirus software is slowing down your PC

The test results of the AV-Test website show that Windows Defender can reduce software installation speed by 54%.

Security is an important issue that is of prime interest in today's technology world. In recent times, two serious vulnerabilities, Meltdown and Specter, have shaken the swimming technology industry, making the processor unable to achieve maximum performance in software applications.

In fact, not only Specter or Meltdown but even anti-virus software also make PC PCs slow to see. This existed for many years but almost everyone was not very interested in how much it affected it.

In testing for the most popular antivirus software in the world, the AV-Test website showed the effects of Windows Defender on PC speed in the image below.

According to AV-Test, a typical antivirus application will affect the PC's speed as follows:

1. 11 - 16% reduction in web page download speed.
2. 9 - 15% reduction in speed of opening other applications.
3. Reduce the software installation speed by 26 - 35%.
4. 7 to 18% reduction in file copy speed.

In fact, some software works extremely well while others do not, so the above figures are only relative. Windows Defender, for example, can cause application installation speeds to drop by 54%.

AV-Test uses high-end PC system with Intel i7 3770 chip, 3.40GHz clock speed, 16GB RAM and Samsung SSD 512GB hard drive in our test. This shows that even with strong computer hardware, reducing the speed caused by antivirus software is unavoidable.

Although antivirus software affects PC speed, they still play an important role in security, especially in the current technological age. If you are interested in performance, consider carefully which antivirus software will best suit your needs.
