This happens to by my dial up file, i have scanned with nod32 and found that this file doesnt seem to be a virus, however avast (my regular scanner) seems to think its a trojan horse.
So is this file a virus, if not how do i make avast ignore it?
Hi there, you can send a zip compress folder of the file that claims to be infected by avast! and send it to virus@avast.com it might be a false positive. If it is, the awil team can fix it on the next update. 
Thanks for teh reply, do i explain the situation with this email?..or just send it?
If you are getting a virus warning that you believe is a false positive, then if you can zip and password protect (‘virus’, will do) the suspect file and send it to virus @ avast.com (no spaces).
Give a brief outline of the problem, the fact that you believe it to be a false positive and include the password in the body of the email. Some info on the avast version and VPS number (see about avast {right click avast icon}) will also help.
Right, the file doesnt seem to be able to be compressed, possibly due to it being blocked, eventhough avast isnt running. The files is 260k, shall i send it as a dll or…cry at my keyboard and then look at porn.
The purpose of zipping and password protecting the attachment is to avoid ISPs, mail server virus checkers deleting it along the way (if it was detected as infected).
What in avast isn’t running? - if you terminated Standard Shield it wouldn’t detect the file when you access it.
What program are you using to zip the file?
Another option is when you access the file with standard shield running from the alert window, send it to the chest, from here you can send it to avast.

[b]Email to ALWIL Software[/b]. The selected file will be sent (by e-mail) to ALWIL Software. You should use this option in special cases only - e.g. if you suspect avast! of a false alarm. Do not forget to attach as much information as possible - the reason you are sending the file, the version of your virus database, etc. Doing so will improve the service to you - the customers.
