That little feeling of unease is hard to ignore. Your laptop, which usually hums along quietly, is suddenly acting strange. Maybe it’s running slower than usual, or you’re seeing pop-up ads where they shouldn’t be. Your first thought might be, “Do I have a virus?” It’s a common worry, but you don’t have to just wonder. There are clear signs you can look for.
Common Signs Your Laptop Might Be Sick
Just like people, a laptop with a virus often shows symptoms. A sudden, significant slowdown is one of the biggest red flags. If opening a simple program feels like wading through mud, it could be a sign of malicious software running in the background. Other warnings include a barrage of pop-up ads, your web browser’s homepage changing without your permission, or new toolbars and programs you don’t remember installing. If your friends mention getting strange emails from your account, that’s another strong indicator something is wrong.
Using Your Built-in Security Tools
Before you panic, it’s a good idea to check with the tools you already have. If you use Windows, you have Windows Security (which includes Windows Defender). Open it and run a full scan. This thorough check will look through your files and programs for any known threats. For Mac users, while less common, viruses are still a possibility. Use the built-in antivirus software, like XProtect, by checking for updates in your System Preferences and then running a scan. Let this scan run completely, as it’s your first line of defense.
What to Do If You Find a Problem
If your scan detects a virus, the software will usually guide you on the next steps, which often involve quarantining or removing the threat. This process isolates the harmful file so it can’t cause more damage. After removal, it’s a smart practice to restart your laptop. To help prevent future issues, be cautious about the links you click and the files you download, especially from unknown sources. Keeping your operating system and antivirus software updated is also crucial, as these updates often include patches for newly discovered security holes.
Noticing these signs early and taking action can save you a lot of trouble. Regular check-ups with your security software are the best way to keep your laptop healthy and running smoothly for years to come.
