Do not worry about GABSharky it is not a virus (if you are going to get a early mirrored copy do check though), mondayz (the author) had his server hacked and the app replaced with a virus (this was probably the biggest upset to flashcarts until darkfader came along with the DS brickers), the person responsible for the virus came clean a bit later in life.
As for VBA my prefered version these days is either VBALink (link support stangely enough) or Kode54's builds (7zip and sse2 support to name but a few advantages), whatever you use though have a look under options -> emulator -> save type and set the options here.
