Ah, thanks for the warm welcome @digital & oh I'm not entirely so positive considering malware does float around on the android market. As for the "scareware", "LoL" guess.. yesterday night, It was indeed a fright. However Airpush detector?! Usually I'm pretty well sandboxing my system its annoying but you're right, so viruses? Okay, but imminent they spread & my only guess is these are mainly "Joke Programs". Last month though, if I noted correctly located a "Downloader" on a the neighbors HTC. I forced him to cold boot lol. Malicious & advertising now? Between the two I compare which may be a problem in the future.
I use several combined methods ensuring linux & open source devices preventions from loss of data. "Botnets" are rising enough, a DDoS attack has happened to me. My fields revolve around a proxy server though, I'm into encryption. I don't use "Rogue Security Software".
