Personally when it comes to my system security I trust very little, I have no doubt that the Treewalk site does state that is is a false positive, but would you take the word of someone who you don’t know who also wrote the software. If (and this is purely hypothetical) it were you and you were asked if there was any malware with your software (any there was), what would you say?
You are right to check but never take anything at face value.
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.
I think that kpurcell was shown how to confirm if it was or wasn’t a false positive using two alternative multi engine scanners. I can’t say if it is a false positive, I’ve never heard of treewalker let alone used it. So all that I could do was to show how to confirm or deny and what to do to help resolve an FP or undetected virus, send it to avast so that later versions of the VPS correct the FP or include a new virus.
That must have been enough for kpurcell as they never made a further comment since August 13th, over three months ago.
