If you are wondering if your virus scanner actually works, all you need to do is the following:
Step 1
Right click on your desktop > New > Text document ( it doesn't matter what you name it)
Step 2
Copy the text below into the document you've just created
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
Step 3
Once you've done that click file > save
If your virus scanner is working it should pick it up, if it doesn't then manually scan the file for the virus!
Note - this is not a real virus, its just to check if your virus scanner is working or not
