Viruses to me are one of the most anoying and pointless things in the internet i meen if you want to download something then you go download it right. But what if this file has a keylogger of a trogen in it. if you haven’t got a security sistem then it infects your computer taking information of maybe you bank details and stealing your money. Lucky this has never hapened for me but it has nearly many times. But because i’ve got norton it protects me so if i were you i would really go and invest in one of these security things preferably norton because you know that it work.
