Dear Loyal Mozilla Users

Today after updating AVG I got a Virus alert on my Thunderbird Portable stating this virus "Obfustat.NPD" was a Threat. I tried to Heal it but it still comes up. I tried to Move to Vault but it still comes up. putting 2 and 2 together - I figured out it is the "newadvsplash.dll" screen that come up when I launch the portable version. Personally I think this issue is AVG fault and needs to be corrected by them. But if Anyone as a clue on how to fix this issue - I would be happy to try it.

** note: this happens on any of the portable applications I have from

I have put a message on AVG forums too about this issue. Because, like I said, I think it is AVG issue not issue.

I had the same problem, but

I had the same problem, but the virus alert appears every time I start an app on Portable Apps (except some apps that I include - Toucan, eMule, CDisplay). It's the same virus (Obfustat.NPD) and the same archive (newadvsplash.dll).
I really enjoy Portable Apps!

Please Re-Read

Please go back and re-read the big paragraph at the top of the contact and support pages which states:

False Positives - Some false positive reports occasionally pop up in different antivirus products in conjunction with portable apps. This is partially due to the compression and portablization techniques used and partially due to a failure of some antivirus companies to fully test their virus definition updates before sending them out to users. If you encounter a false positive, please test the file in another antivirus product before reporting the issue to us in the forums to ensure that it's not an error in their software. Several companies make available online scanners for individual files, so you won't even have to install software (, Jotti). You can also use ClamWin Portable. Thanks for your help.

Virus reports from a single antivirus package mean absolutely nothing and will be ignored.

This isn't the first time AVG has had false positive issues and it won't be the last.

Sometimes, the impossible can become possible, if you're awesome!

Well, I did read. I reported

Well, I did read. I reported because it's annoying see the AVG alert. I hope they fix this.
I'm still using and enjoying portable apps.


But, we can't do anything at all about AVG's screw up. Only AVG can fix AVG.

... besides, my original reply was to Mark, not you, because he reported it without bothering to confirm it.

I only report because I hope that someone contact AVG to do something that could fix the problem. If you became upset, sorry.
Most of forums that I take part, the major intent is to help. Portable Apps is really great. I use and I stimulate many friends to use Portable Apps.
