7 signs that your laptop has been hacked

When you are sick, your body will surely have signs to recognize. Just like when a laptop has a problem, it will also have signs for its owner to recognize. Let’s find out with lassho.edu.vn the problems of a laptop when it is hacked by hackers!

Application is slow or crashes

The most noticeable sign when a computer is infected with malicious code is that the applications are slow or constantly hang. The reason is that malicious code often runs in the background and secretly “eats” the resources of the application while it is active.

You can determine which applications are at risk of getting infected by checking to see if the processes are running on the computer through the Task Manager .

By using the keyboard shortcut Ctrl + Shift + Esc and going to the Process tab , you will see all the current tasks on the computer and how much processing power they are using. If this level is higher, even reaching 100%, then those applications are definitely the “culprits”.

You use more data than usual

Every Internet provider has tools that monitor your monthly bandwidth consumption. Check the Data Usage Meter or Data Monitor , depending on your provider, to compare data usage from previous and current months.

If you detect a sudden spike in your data activity even though you haven’t downloaded anything new, chances are you’ve been infected with malware.

Can’t download videos and web pages

Don’t think that the failure to download videos and web pages is due to a weak Wi-Fi connection, because malicious code can also slow down Internet traffic by hijacking DNS.

Hackers can redirect your traffic to unsecured servers instead of secure ones. If your router’s DNS settings are compromised, every time you visit a website, you’ll be redirected to a phishing site instead.

To check DNS settings, you can use online tools like F-Secure Router, CloudFlare or Quad9.

File can’t be opened

Unable to open files is one of the most obvious signs that your system has been hacked. In the worst case, the malicious code not only prevents you from opening familiar files, but also “eats” all the data contained in the files.

You can try to fix the problem by booting to safe mode . With safe mode, you can safely remove and uninstall any program or file that behaves abnormally.

To activate safe mode, search for System Configuration, select Boot, Safe Boot, Minimal, click OK to confirm and restart the computer.

Many ads pop up automatically

In addition to slowing down apps and eating up data, the malware adds bookmarks and modifies the ads you see while browsing. Instead of the usual ads that you will receive, hackers will replace them with inappropriate or malicious ads.

On Windows, you can clean up ads with SpyBot Search & Destroy.

Device restarts automatically

When updating software and installing new apps, the device may reboot. However, the sudden automatic reboot is another story, it shows that your device is no longer safe.

You should use Full Scan to verify what your computer has been updated to and limit automatic restarts when infected with malicious code.

Suspicious online activities

Once the device is attacked, the hacker will have your username and password information on many online platforms such as bank accounts or social networks.

If one day you find out that your social media account automatically sends messages to get acquainted or deceive someone, your device itself may have been hacked.

Right now, pay attention to see if the above signs have happened to your laptop. If it has been and is happening, bring your laptop to be checked immediately for the best remedies!
