Viruses and malware are sneaky. They're designed to hide on your computer while causing problems in the background. But there are some telltale signs that something's not right. Here are the top 5 warning signs that your computer might be infected.
1. Your Computer is Suddenly Very Slow
If your PC was running fine last week but now takes ages to open programs or load websites, malware could be the cause. Viruses often run hidden processes that use up your computer's resources, leaving less power for the things you actually want to do.
What to look for: Programs taking forever to open, the spinning wheel appearing constantly, or your computer's fan running loudly even when you're not doing much.
2. Strange Pop-ups Keep Appearing
If you're seeing pop-up windows — especially ones warning you about viruses and asking you to download something — that's a major red flag. Ironically, these fake "virus warnings" are often the virus itself trying to trick you into installing more malware.
What to look for: Pop-ups that appear even when your browser is closed, or warnings that look slightly "off" compared to real Windows notifications.
3. Programs You Don't Recognise
Have a look at your installed programs. If you see software you don't remember installing, it could be malware. Some viruses install additional programs to help them stay hidden or steal your information.
What to look for: Unknown programs in your Start menu or taskbar, browser toolbars you didn't add, or your homepage changing without your permission.
4. Your Browser Keeps Redirecting
If you search for something on Google but keep getting redirected to strange websites, or if clicking links takes you somewhere unexpected, you might have a browser hijacker. These are a type of malware that takes control of your web browser.
What to look for: Your homepage or search engine changing on its own, being redirected to unfamiliar sites, or seeing unusual ads on websites that don't normally have them.
5. Your Antivirus Has Been Disabled
Many viruses are smart enough to disable your antivirus software first, so they can operate without being detected. If your antivirus suddenly stops working or you can't open it, that's a serious warning sign.
What to look for: Your antivirus icon disappearing from the taskbar, error messages when trying to run a scan, or being unable to visit antivirus websites.
What Should You Do?
If you've noticed any of these signs, it's important to act quickly:
- Don't enter any passwords or personal information
- Don't download anything claiming to "fix" the problem
- Disconnect from the internet if you suspect something serious
- Get professional help to properly clean your system
