And do it better than any anti-virus application on the market. Norton Anti-Virus came with my new laptop but I never activated it. One day, I decided, lets see if after over 10 years they've improved any at all.
Shortly afterwards, I couldn't keep a wifi network connection for longer than a few minutes. I had to reboot a few times until finally, it would stay connected. So I started to really take a look at this "new" problem to determine how and why this was happening. What did I install that could touch my network on a regular basis. "NORTON"!!
Add / Remove programs and uninstalled it. Wifi connection is hasn't dropped since. I don't know what it is about Norton Internet Security, Norton Anti-Virus put out by Symantec but after 10 years it seems, its still "s***s" like a Hoover.
What are you using for Windows 8.0 / 8.1 and how is it working for you?
