This just started yesterday. Whenever I open my outlook and reply to a message, 5-8 pop up windows show up (i'd attach an image but it won't let me). It's asking me if I'd like to download a file. Each pop up window has a different file name, it says it's a Firefox Document and it only gives me the first file location not the whole string so I can't find it in my files. I've run my security system and it doesn't see it, called our help desk, they can't find it, cleaned my internet files and it's still happening. It only happens when I'm in email and almost always when I open an email to reply - or start a new email!! It's maddening!!
