    Why Dr.Web Security Space for Linux is not mentioned in this article? This is effective and very much affordable solution with 90 days free trial. It definitely deserved to be mentioned. Bitdefender doesn’t exist for Linux anymore F-Prot is extremely old and Comodo cannot be installed on modern Linux either. Please update the article.
