Hello, The font in my ESET NOD32 Antivirus 3.0.684.0 on Windows XP SP3 GUI changed yesterday. I'm not sure why - the only thing I did was update my Windows Live Messenger to the 2009 version from the 2008 version and then receive (after some difficulty) update 3995, which was supposed to be a pretty big update. I don't have a screenshot unfortunately. The font that it has changed to is identical to that of the font in the ESET NOD32 Antivirus GUI on my Vista machine. I thought the font I had before was just an XP font and the font on my Vista (which is now on my XP and Vista) was just a Vista font. Now (I think) I have a Vista font on my XP NOD32 GUI. Why did my font change? Did Windows Live Messenger 2009 screw it up? Thanks, Mark. If someone running XP could post a SS of what the their font looks like in the GUI of EAV - where it says "Protection status, Computer scan" etc that would be great.
