Quartus won't compile because antivirus

Hi,

I tried to run Quartus II for the first time. When I attempted to compile a design my antivirus software quarantined one of the files in Quartus II.

Is this a known false positive or do I actually have a Trojan?

The detection type is 'generic' meaning that the file looks suspicious to the antivirus but no specific threat was detected.

OS: Windows XP SP3

App: Quartus II 32-bit Version 13.1.0 Build 162 10/23/2013 SJ Web Edition

The above was downloaded from altera.com

AV: Avast (Free edition) Ver: 2015.10.0.2208 Virus Definitions Ver: 150220-0

Detection name: Win32:Evo-gen

Detection file: C:\altera\13.1\quartus\bin\neto_vlgo.dll
