James Marey teaches how to test whether your Anti virus is still working perfectly. First right-click anywhere on your desktop, go to 'New' and select 'Text Document' to open a new document. Now find some text containing a virus from the internet or you copy the text from the video. After entering the text, go to file and save the document. Now if your anti virus is working perfectly it will pop out a virus threat indicating the file you just saved. Finally select the appropriate option to remove the virus.
