How do I stop spam on my Nexus 7? I have just purchased a Nexus 7 tablet and on the whole I am very pleased with it but I have one major gripe. It has been a return to the bad old days with a flood of Spam messages. On my home PC I stemmed the flow, first by installing a spam filter and now with Windows Live Mail. I have looked, so far in vain, to find an effective and preferably free spam filter in the Google Play store, but the user reviews are not encouraging. Do you have any recommendations? Keith Smith, by email Try MailWasher, it's a free Spam Filter that uses a large database to identify and zap dodgy messages while they are still on the server, so they never get anywhere near your PC. It also learns to identify craftily composed messages that can slip through the net. Sadly recent releases of Mailwasher Free for the PC have become a bit unwieldy but Firetrust is trialling a fresh new Android version and so far it looks very promising. If you would like to give it a test run sign up for the beta test by going to http://goo.gl/LJ8sT. There is also a trial for an iOS version that runs on iPad, iPhone, and iPod Touch but Apple make it quite difficult to participate in beta tests and to install it you have to know your device's UDID number. This involves a fair amount of faffing around but if you want to go ahead there are more details and signup instructions at: http://goo.gl/UUPE1.
