Viper: Your are not exactly justified..... Thus - your dad is not wrong..... He may not be spot on.... but he isn't wrong....

Each AV company has to get a copy of an actual virus, study it, determine it's characteristics, find a signature and publish it. Now, if Norton gets it 1 hour before Mcafee then they _should_ come up with the new definition sooner.... and they probably would.

When it comes down to it it's a matter of what you prefer and in this case it seems like you prefer Kaspersky while your dad prefers Norton..... We could argue "Symantecs" all day, , but in the long run we will all be right about major AV systems....

The "name" systems work.... On any given day any one will work better than any other.... it's a fact of life.....

Rider: I like Norton/Symantec..... But I use 2 AV systems before mail is allowed into my network..... Belt and braces....yeah.... am I right using either AV system over another.... I don't really know..... They are all so close to being "right"
