Hi, welcome to the forums.
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.
You could also check the offending/suspect file at: Jotti - Multi engine on-line virus
scanner
www.virusscan.jotti.dhs.org if any
other scanners here detect them it is less likely to be a false positive.
