WLMail problem with Avast

Hello… been using Avast and Windows Live Mail for years but only now experiencing some problems with it. Whenever I open WLM and its downloading the mail, I get a pop up that Avast detected a virus (an .eml file in AppData). It gives me a choice to fix automatically. But whenever I click that choice, the pop-up warning doesnt go away, I click again a few more times and WLM freezes. For 2 days have not been able to use WLM. This on Windows 7 and Windows 8 (dual boot) and latest Avast free 9.0.2008. I have uninstalled Avast for time being and will use something else temporarily. I hope it will be fixed soon, Avast is still the only free AV I trust and hope to return to it soon.
