I have noticed that if I ry to send and e-mail with no subject in the subject line in Lookout Distress (OE) I get the same warning on clicking on send. I also get the same warning if I receive an e-mail with no subject line as well. I guessed it’s because I have heuristics set to high and therefore Avast treats any e-mail whit a blank subject line as suspicious. Well at least it lets me know the e-mail scanning is working fine, unlike some other AV Products I could mention…
