I installed an AntiVirus on my Windows computer, and now the system is slow. Is it normal or should I worry?

An AntiVirus application can slow down a computer if it does not have the minimum required resources. Which AntiVirus did you install on your computer? Can you tell us the OS, RAM, and other specifications?

I have Norton protection on my PC.

Norton antivirus is a heavy application.

I too had similar experince as ron. I removed the antivirus and the system started operating faster.

My experince says yes. Anti virus slows down computer.But its better keep anti virus to be safe.

No issues on my PC. Only a lower end computers slow down with an Anti Virus.

I use Avast antivirus on my Windows laptop. I never felt it slowing down the device. That is my experince.
