If people are trading , thay need ,execution screen, and a screen for charts ,it seem,s to me that to keep your lifeline online why not pay £40-£50 for norton AV-. iF you go for cheaper choices it seem,s like a bit of a gamble,It,s like compareing spread betting with tradeing ,YOU go for the best spread, same thing as going a good AV ,or not so good one ??
