Eact time I go phoronix with my droid, I get a full screen system looking page telling that my browser memory is full and I need to download an app to clean. No way to exit this intrusive aD except pressing back and go phoronix a second time.
Thanks to that, I just found that adblockplus support the android browser
Those types of ad redirects are very common with malware. As in, your phone might have an app with malicious code embedded.
I'm saying this because I have never once gotten one of those page redirects.
