Test your anti-virus software safely

The European Institute of anti-virus development (eicar) provides a file: The eicar standard anti-virus test file, which is a test standard provided by anti-virus software vendors worldwide to check the installation of anti-virus software. You can easily create this file:
Open notepad and copy the following line of text to save the file. Select "all files" for the file type and the file name is "eicar. com ".

X5o! P % @ AP [4 \ pzx54 (P ^) 7cc) 7 }$ EICAR-STANDARD-ANTIVIRUS-TEST-FILE! $ H + H *

After the copy is successful, the generated file should be 69 or 70 bytes long.
Now you can use your anti-virus software to check this file. If the report finds a virus (in fact, this file is only used for testing, not virus ), it indicates that your anti-virus software has been successfully installed on your computer and has been effectively maintained on your computer.

Haha, fun, good :)
You can try ....

I used NOD32 only when I renamed it to. com. It seems that when someone else only has one TXT file, I can find out if I want to use another anti-virus software? :)
