A slow computer can turn you into a detective. You start investigating the clues, trying to find out what happened. You might even Google “How to tell if you have a virus” or “Warning signs your computer is infected.”
A Google search can easily send you down a rabbit hole, though. That’s why we took the time to write a helpful guide you can use to solve the mystery. There are a few obvious signs, like a parade of popups whenever you open your laptop.
But you should also know the more subtle signs of a virus. Not all infections are in your face — some lurk on your system for a while before taking over. Here are some surefire signs your computer is infected with a virus.
1. It’s hot to the touch
When you accidentally download malware, your computer’s internal components start working overtime to handle it. They’re not supposed to work that hard.
The fans are hustling to cool down the system, and eventually, they might wear out. Once they go kaput, your inner circuitry might even melt. Tap or click here to see how to keep your gadgets cool.
Speaking of which, watch out for strange sounds
Your computer may try to warn you that something is wrong. Although some types of malware can hide warning messages, they can’t overpower the sound itself. If it sounds like phantoms are moaning or bells are ringing, take that as a warning sign.
2. It keeps crashing
Desktop apps that previously worked wonders suddenly stopped working. It might be an issue with the developer, so check out official sources for news of any problems.
You might find out your software and hardware aren’t compatible, which may cause technical issues. If no other customers complain, the problem may lie within your system.
You should be especially worried if you can’t open your antivirus program. Dangerous malware like ransomware digs its claws into your favorite files, stopping you from opening them. Even if you aren’t dealing with ransomware, you may have a nasty virus overtake your system.
Here’s one way to fix the program: Reboot your device in Safe Mode. Tap or click here to use Safe Mode on Windows, macOS, Android and iOS.
3. Your device restarts itself
Of course, sometimes your computer needs to restart when an update comes out. But you will always get a heads-up before that happens. You can even set the time you want your system to restart.
Not so with a virus. It won’t ask you for permission. There’s no warning whatsoever.
Sudden restarts are a sign that a hacker is installing malware. That’s because you usually need to reset your system to install harmful software. If someone is breaking into your system from afar, they have no qualms about cutting you off in the middle of whatever you’re doing.
4. Videos take forever to load and you have less data to use
By now, you know viruses can make your device hotter because your internal circuits work harder than they were designed to. But your hardware isn’t the only casualty. Your storage space takes a big hit, too.
Although some level of buffering is normal, it shouldn’t happen all the time. Malware brings your internet traffic to a screeching halt through DND hijacking. They’re redirecting your internet traffic to unsafe servers.
Compare this to a VPN service, which redirects your traffic to safe servers. When VPNs do it, they’re protecting your privacy so advertisers can’t follow your activity. When hackers redirect your traffic, they’re trying to squeeze as much private data from you as possible. It’s a huge security risk.
That’s why you should check your router’s DNS settings. Free tools like Cloudflare or Quad9 offer advanced hijacking protection. Tap or click here to make your router hacker-proof.
