Your item #3 was pretty eyeopening. The more articles I read, the more paranoid I get. #1 was also good. Once compromised, there's no way out except to reformat.
I guess one really big benefit of AlphaShield is that the connection is physically cut off anytime I'm not online, so that malware can't run autoclickers or wwwsh and successfully access the internet.
Of course that doesn't prevent it from working while I'm connected. I guess you just have to be careful and realize despite that, you still may get whacked.
