I first had northon antivirus 2003. And that program scanned the files that I recieve or send with msn messenger.
This might be a stupid qeustion but… Does avast scan those incoming files and block them if they are infected?

This may help answer your Question gersom
Instant Messaging" - Provider Settings
The Instant Messaging provider protects your communication programs. Many communication programs are capable of sending and receiving files from other users. This way, it is rather easy to get an infected file and spread it further. Some viruses are even able to spread using the communication programs, without the user knowing about it. The Instant Messaging provider avoids this kind of infection. It monitors the folder where the received and sent files are stored. Whenever the content of the folder changes (a new file appears, a file is modified, etc.), avast! immediately performs a scan. On Windows NT, 2000, and XP operating systems, all the files modified by the communication programs are scanned (even outside of the mentioned folder).
The following communication programs are supported:
AIM (AOL Instant Messenger)
Gadu-Gadu*
gaim*
ICQ
IM2 Messenger*
Miranda*
mIRC*
MSN / Windows Messenger
Odigo*
PalTalk Messenger*
Psi Jabber Client*
SIM (Simple Instant Messenger)*
Skype*
Tlen*
Trillian
Yahoo! Messenger
Thanks…
Then I’ll uncheck the checkbox in msn for scanning with a antivirus program… (Because it’s just starting avast when I recieve a file…)
If you still feel uncomfortable relying on “automatic” Messenger protection provider in On-Access Scanner module (btw, do you have it enabled and running ?), you can always go to MSN messenger TOOLS / OPTIONS / FILE TRANSFER and put a checkmark under SCAN FILES FOR VIRUSES and paste this line in the box:
C:\Program Files\Alwil Software\Avast4\ashQuick.exe
Thanks for helping me out ;D.
