Short answer: No virus scanner needed when using Vector Linux.
Long answer: A virus scanner may be desired to reduce the possibility of re-distributing viruses which affect other platforms. Personally, I do not use one. I try to use common sense and not forward emails with attachments or distribute files in other ways. This will probably change in the future, but for now I'm enjoying flying under the radar of malware attacks.
Ok, nightflier... I now what to do now.
And yes, i must send E-Mails with attachments sometimes, i hope that i can work safely than.
Thanks again and have a nice day further.
