5 Signs Your Computer Has a Virus (And What To Do)
April 13, 2026 | Wade · PC Help Hero
Viruses and malware are sneaky. They don't always announce themselves. But your computer usually gives you clues. Here are the five most common warning signs.
1. Your Computer Is Suddenly Very Slow
If your computer used to be fast and now takes forever to open programs or load web pages, a virus could be running in the background using up your computer's power.
2. You See Pop-Up Ads Everywhere
Pop-up ads that appear even when you're not browsing the internet are a classic sign of adware — a type of malware that bombards you with ads.
3. Your Browser Homepage Changed
If you open your browser and it goes to a website you didn't choose, something has changed your settings without your permission.
4. Programs Are Opening on Their Own
If programs open or close by themselves, or if your computer does things you didn't ask it to do, that's a red flag.
5. Your Friends Are Getting Strange Emails From You
If people tell you they received weird emails from your address that you didn't send, your email account may be compromised.
