I am presently running McAfee VirusScanProf. 7.0 & Firewall. The virus scan has been tempramental for a long time - frequently requiring me to go in & "launch virus scan" then click to start active file checking. Mcfee support upgraded me to some later version, but the problem has persisted. Recently I sometimes get error messages - a whole series of boxes opening up to warn me that the something cannot connect to application files( please forgive my vagueness - I'll make a note next time it happens) I do not want to spend any more cash on this PC as I hope to upgrad in a couple of months. I do weekly updates of signature data files & I also run Ccleaner & AdAware. Does anyone know of a reliable virus checker & firewall to run on such a low spec. PC ?
