This is unfortunate. While Linux may be "more" protected by design, it still has vulnerabilities. Beyond that, however, is the fact that I interact with non Linux users all the time and I could inadvertently share a malicious file that doesn't impact my computer with other vulnerable computers on the network simply because I don't have an anti-malware solution for my computer. This is clearly a known possibility because you offer anti-malware solutions for businesses that have Linux servers on their networks. It is truly sad that it appears that there won't be an anti-malware solution for home Linux users until some incident occurs - in other words, when it's too late.
