Antivirus NOT detected

Why would all of a sudden my Pc stop detecting the perfectly running antivirus program?

Re: Antivirus NOT detected

well remove it and re-install it ... mean while never open attachments and the like unless you know the sender well and dont install freeware and unknown programs on yr machine. No experiment with softwares on it.
