Swordmaker nor any other MacBott have told you any such thing, less likely or unlikely yes, impossible? No.
I have been on line with my Macs a little over 20 years and have never been infected, and I run no virus ware because I consider most of it as obnoxious as the Virus it is supposed to protect me from.
If I am so unfortunate to encounter a Virus, I know a fix will be posted on MacSurfer.com so I don't worry over concern trolls like yourself.
I too have never received a virus no anyone in my family. I guess windows is just as good if not better because there are 5 people I’m vouching for and you only mentioned 1.
That’s some great logic there isn’t it?
