Welcome to Blackview (Supply budget work & play laptop and mini PC) blog. Hope the guide helps.
In today's digital world, the risk of cyberattacks is always present. To use a Windows 11 mini PC, like Blackview MP100, is usually safer than use a Windows 7 mini PC. It’s crucial to know the signs that your computer might be hacked so you can act swiftly. Here’s a guide to help you identify if your system has been compromised.
1. Unusual Slowdowns
If your computer becomes unexpectedly slow, it could be running malicious software in the background. Malware or unauthorized programs can consume system resources, leading to performance issues.
2. Frequent Pop-ups and Ads
An influx of unexpected pop-up windows or ads, especially when you're not browsing the internet, could indicate adware or spyware installed on your system.

3. Programs Opening Automatically
If programs start launching on their own or if you notice software that you didn’t install, it could be a sign that a hacker has gained access and installed malicious applications.
4. Antivirus Warnings
Antivirus or anti-malware software frequently alerting you about threats could be an indication that your system is infected. Pay attention to these warnings and investigate further if they occur often.

5. Unusual Network Activity
Monitor your network activity by checking your system’s network usage. If your internet connection is being used heavily when you’re not doing anything online, it might indicate that a hacker is using your system for malicious activities, like sending data or launching attacks.
6. Changes to Files or Passwords
If files are missing, corrupted, or if your passwords are suddenly not working, it could be a sign of a security breach. Hackers often tamper with files or change login credentials to lock users out.
7. Unknown Account Activity
Check your online accounts for any unusual activity, like unauthorized logins or changes to your settings. If you receive alerts about suspicious logins or password resets you didn’t initiate, your computer could be compromised.
8. Increased Use of CPU or GPU
Unexplained high usage of your CPU or GPU, especially when you’re not running intensive programs, could indicate that your system is being used to mine cryptocurrency (cryptojacking) or for other illegal purposes.
9. Browser Redirects and Toolbars
If your web browser keeps redirecting to strange websites, or if you see unwanted toolbars or search engines, your browser could be hijacked.
10. Unusual Desktop Behavior
Another telltale sign of a hack is abnormal desktop activity. For instance, when you drag an open program (such as a browser window) across the screen, you may notice a graffiti-like effect, with the desktop being covered by these streaks or "trails" left behind. This could indicate that malicious software is interfering with your graphical interface or system processes.
What to Do If You Suspect Your Computer Is Hacked
- Run a Full System Scan: Use reliable antivirus or anti-malware software to scan your computer and remove any threats.
- Disconnect from the Internet: Immediately disconnect your system from the internet to prevent further access by hackers.
- Change Your Passwords: Use a secure device to change all important passwords (email, banking, social media).
- Update Software: Ensure that your operating system and all applications are up to date with the latest security patches.
- Reinstall the Operating System: If all other measures fail to restore your computer’s normal functionality, performing a full system reinstallation may be necessary. This involves wiping your system clean and reinstalling the operating system from scratch. While this is more drastic, it effectively removes any malware or corrupted files, ensuring that your computer is reset to a safe state. In extreme cases, you may also need to format all storage drives to ensure that no hidden threats remain. However, be sure to back up important files before taking this step.
- Seek Professional Help: If the issue persists, consider consulting with a cybersecurity expert.
By staying alert and monitoring for these signs, you can protect your computer and personal information from hackers.
