I’m currently running a Windows 8 PC. I’m fully aware that DOS programs like EICAR are incompatible with my system. What I’m worried about is my anti-virus, which Windows 8 appears to lack, is not giving security warnings for files that are potential threats to my PC.

C:\Users\sophos\Documents\eicar.com
C:\Users\sophos\Documents\eicar.com is not a valid Win32 application
OK
What would happen if one day I run a harmful program? All I’m saying is, Windows 8 doesn’t feel like it’s keeping my PC safe enough. What can boost my system’s security?

Hallo Annie,
It seems like the antivirus you have installed is not compatible with the operating system you are currently using on your computer. You OS is Win 32, and therefore you will need to make sure that the antivirus is a win 32 application.
But if you have been using the antivirus without an issue till lately, the possible reasons as to why that could be happening are the following:
