Hello + thanks for your help in advance ;-)
I always use Winamp as my audio player and today randomly recieved the following message from avg anti-virus free (up to date):



I've reported it/sent to analysis. I've tried removing the threat as a power user as I uninstalled winamp and installed it again. After that process, winamp will not repond and the above will come up again. This happens if I try to open winamp every time now... winamp just won't respond and avg will tell me about zlib.dll
Moving to vault did not help either. Neither did heal. Is it a virus, or a false positive?

Here's my hjt log:
