I downloaded a free software program the other day to convert audio files into WMA for our new VW Tiguan's SD card and got with it a free complimentary ad generator virus/malware that infected my laptop to such a degree that I cannot use it at present. I have since downloaded Avast as well as a malware removal program but had limited success (it identifies the bugger, puts it away, but it keeps on coming back). Our local computer repairers/suppliers cannot resolve it either and suggested a entire Windows removal and re-installation process... Any suggestions/help?
