I am have an awful time with DEP not allowing me access to several sites and downloads. I get the DEP is shuting down Internet Explorer. I have tried everything. I've been on Window's website looking for answers...nothing helps. I would love to banish DEP from my computer!! Anyone with the same problem??? My computer is only a few months old runs on Vista 64 bit and is shuting down on items I have logged onto forever! I am furious!!!
