Now I am getting annoyed!
Those ****ing parasites - "Evidence Eraser" - have got themselves a TON of domain names, and spammed the hell out of the search engines.
Never EVER buy Evidence Eraser! http://www.heidi.ie/eraser/
BCWipe IS freeware, and they advertise some other products on the page - fair's fair - and I's much rather deal twith them for those other products, than the miserable jerks behind Evidence Eliminator.
