What should I pay attention to when using computer? Will it be poisoned?

Be careful of files with EXE and INI suffixes, and generally don't download such files unless you know what these are and are sure you need them. After downloading the RAR file, check the virus first, and you can't decompress it directly. Don't just click the EXE suffix file inside, especially the file with attractive file name or file size less than1m.

For beginners, the security of installing anti-virus software will be better than what they pay attention to, so install a better anti-virus software. I suggest you install 360 Security Guard+Red Umbrella for antivirus.
