What Is a Computer Virus? How It Spreads & How to Stop It | Avast

You use your computer every day to work, shop, stream, and connect with the people and things you care about. But what exactly is a computer virus, and how does it manage to spread so fast? In this video, we explain what a computer virus is, how it attaches to files and programs you trust, and how it activates, copies itself, and spreads to other files and devices—just like a biological virus.

What is incognito mode and is it really safe?

Ever used incognito mode and thought, “Nice, now no one can see what I’m doing?” The truth is, incognito mode doesn’t make you invisible online. Incognito mode helps keep your activity private on your device by not saving your browsing history, cookies, or autofill data once you close the window. That’s great for shared devices or logging into multiple accounts—but it doesn’t stop tracking beyond your browser.

Is AI dangerous?

AI is everywhere—writing emails, creating videos, even cloning voices. But artificial intelligence also comes with real risks, including privacy concerns, deepfakes, and smarter online scams. Artificial intelligence learns by spotting patterns in massive amounts of data—and that power can be misused. AI tools may collect personal information, create realistic fake content, or help scammers craft messages that look completely legit.
