In the digital age, protecting computers from cyber threats is extremely important. However, not everyone recognizes early warning signs that their device is infected with a virus.
Here are the most common signs and recommendations from foreign experts to help users proactively prevent them.
Unusually slow-running computer
One of the most obvious signs is a sharp decline in computer speed, even if not running many applications. According to Mr. Brian Honan - an international cybersecurity expert, Executive Director of BH Consulting (an independent security consulting firm based in Dublin, Ireland), when viruses operate underground, they consume system resources, making computers sluggish even without any heavy programs running.
Strange software and automatic advertising appear
If you see unknown software appearing after startup or the browser continuously opening the advertising tabs, it is very likely that the device is infected with malware or adware. These programs are often installed through unsafe download links or when installing free software.
browser changes settings
You open your browser and discover that your homepage has been changed to a new website, or the default search engine is no longer Google or Bing, which could be a sign that your device has been hacked. Some types of malware have the ability to take control of browsers and guide users to pages containing malware.
Documents that are encrypted or cannot be opened
When personal files are suddenly encrypted or re-rooted, along with a payment request, there is a high possibility that you have been attacked by ransomware. This is an increasingly popular and dangerous form of attack.
Slow response when connected to the Internet
Viruses or malware can send data from the user's computer to the server of a virus that you do not know. This not only consumes bandwidth but also causes a significantly slow Internet connection.
Note
Mr. Honan emphasized: Always update security software, do not open attachments from strange emails and avoid accessing websites of unknown origin is a simple but effective way to protect your device.
In addition, users should regularly back up data and use reliable virus terminal software.
Recognize early signs to help you act promptly, avoid data loss and ensure the safety of important personal information.
