Can anyone give any advise about asking for refunds for software purchased online from the US? I'm in S E Asia.

I recently found I had W32.Sinnaka.A@mm and Schmitfraud-C on my PC so I bought a license for "Spyguard" because this was one of the programs recommended by the Microsoft Security Centre web page that kept coming up. (I tried the freeware SpyBot which detected it ok but couldn't get rid of it)

Spyguard couldn't remove the Schmitfraud-C either and it was always there when I re-scanned. It also kept exiting unexpectedly and provoking an MS fault report.

I've since replaced it with another program that got rid of both first try.

Under these circumstances, would it be normal to delete the software and expect a refund? The vendor sent me the license key so unless there some way of detecting my IP and preventing me from using the program illegally, I guess I'm asking them to trust that I will delete the program.

Sorry, I'm not very experienced with buying vuirtual goods on-line. It's no big deal to write the money off but I'd rather not do that unless I have to. Any advice would be appreciated.
