Right.. I think I can work this one out.http://en.wikipedia.org/wiki/Acer_Aspire_One
They did models which shipped with Linpus Linux (A skinned Fedoora 8). The internet icon the OP refers to is almost certainly just an icon linking to Firefox.
Given that the machine is very much Linux ready I would suggest installing the latest 10.10 Ubuntu Netbook Remix on it as Linpus never really got of the ground and was frankly a bit pants.
If you want to fix it with Linpus then I suggest following this guide:http://dailycupoftech.com/2008/09/02/diy-acer-aspire-one-recovery-usb-device/
that will allow you to install a clean copy of the latest build which should fix the problem.
