[font=Segoe UI] Hi MrGdub28901,

From what I know, Yahoo! uses Norton Antivirus as it’s default scanner. avast! wont be conflicting with it since the file is scanned separately, on your computer (avast!) and in Yahoo!'s server (Norton). If I made a mistake, please forgive my feeble mind.

thanks…hope you are right, dont seem to be causing any problems…I guess as long as something is scanning for viruses its okay
