Simply follow these steps:ġ – Double-click the Avast icon that’s located in the system tray (at the bottom-right corner of the screen). Luckily, it’s very easy to prevent Avast from adding their signature line to your outgoing emails. It really is an outstanding antivirus product! Rick’s answer: Adam, I’ve been using Avast for several years and I frequently recommend it in my blog posts. I actually don’t mind the ad in my personal emails since Avast allows me to use their software for free, but I don’t like them showing up in my business emails. I was just tipped off by one of my customers that Avast is placing what is essentially an ad promoting their software into the footer of my outgoing emails. I know you use it too, so I thought you might be able to help me solve a problem I’m having with it. Question from Adam G.: I’ve been using Avast Antivirus for a few months, and for the most part I really like it.
