I am using Windows Vista Home Basic. Recently, I experienced a problem in Windows Live Messenger. Every time I receive a file that my friend sends me a file, after I have accepted the file and fully downloaded it, an error message in red will show up, saying: Virus scan failed! Please check this folder "File Transfer" I am still able to open the received file though. I have configured my antivirus to scan the received files already and my antivirus subscription is still valid and I also made sure that it was turned on. I am using Avast! Antivirus Home Edition. I do not think that there has anything to do with my firewall as I am using Windows Firewall and it did not inform me that it blocked any features of Windows Live Messenger. I never have had this problem before. I am in a dilemma. Could someone please help me?
