In today’s digital age, laptops have become an essential tool for daily life. We store our personal and professional data, access the internet, and connect with others through our devices. However, with the increasing reliance on technology, the risk of malware and virus infections has also grown. Windows 10, being one of the most popular operating systems, is not immune to these threats. So, how do you know if your Windows 10 laptop is infected with a virus?
