-- Red (VM SH2 AC Beta tester) Running on 200Mb VM service with SH2 AC in Modem Mode, with a ASUS RT-N66U router. With this setup I get Fantastic WIRED and WIRELESS Signals in my home. I dont work for VM. But I work in IT, and I know my tech. My advice is at your own risk.
You also need a free anti Walmart, try malwarebytes, I've used it for a few years.
As with antivirus, you need to regularly update and run to ensure you stay clean. It becomes much mor important if you use the PC for banking other sensitive stuff, in that case I would (and do) update and run every day the PC is switched on for anything important
