There have been a number of security and system attacks by viruses and malware on my computer, especially since I started using the laptop and mobile devices. The one I remember well is copying the files from the internet shops to my laptop through a USB drive, where the virus came across my laptop and infected it. This infected a lot of the original files that were already on the laptop, as the files were unreadable or caused errors when I tried to access them, but I couldn’t notice the type of virus. This caused data loss without knowing how to recover it, and the lucky thing was that I only had some data on the laptop at that time.
I could not let it happen again and was always cautious about transferring the files, downloading, opening, and clicking the attachments and links from insecure sources. I will also try to prevent malware attacks by updating the security system on the operating system, running the anti-virus software up to date, using reputable antivirus and anti-malware software, practicing safe browsing habits, and performing regular data backup.
