I just downloaded Avast a few months ago and believe it’s the most recent version that I have. I just received a message 5 times in a row alerting me that a Trojan Horse has been blocked, and when I opened it up to receive more information it told me that it was from a website I was not on. I’ve since closed every webpage except for Facebook, my e-mail, and the Avast forum and haven’t received another notification, but it’d be helpful to know if it was a glitch in the system or not.
