Outgoing email error

when sending and email to a new address, an error message stating that email may contain a virus, is displayed. Continuing allows email to be sent.

a second email to same address does not display message.

what are settings to stop message being displayed when a new address is used

XP Pro and OE 6.1 used.

If you`re sure the email is clean, you should manage the Heuristics tab of settings.
These Heuristics settings are into Internet Mail provider settings.
The number of identical emails that could be sent could be configured there.

message only contains one word

computer has been scanned for spyware using adaware, spybot and windows defender
Avast has been run

how do i access heuristics. i cannot find this in either avast or outlook express

Left click the ‘a’ blue icon.
Click ‘details’ buttom to expand the options (if they’re not expanded right now).
Choose the Internet Mail provider at left.
Click the ‘customize’ buttom.
Browse for the two Heuristic tabs.

Check on help files the meaning of each Heuristic option :wink:
