I have the free version of Avast installed, and usually it's great. But today, out of nowhere, Avast gives me a pop-up advertising Google Chrome. Now, this would be pretty annoying all by itself (most people get antivirus software to avoid programs that randomly pop-up ads, among other things). But the fact is, I already have Chrome installed, and I was running Chrome when the ad popped up! Moreover, the text of the ad seems to recognize this, saying, "Along with avast! Free Antivirus you installed the Google Chrome browser. Used by our own Virus Lab, Google Chrome is our choice for most secure web browser." Since I've already installed Chrome, and Avast seems to know I've already installed Chrome, why the hell am I getting advertising for Chrome?!
