Try surprising the intruders by switching to Linux. All problems solved.
You can continue using Windows 7 on a PC that's not connected to Internet, or - in a dual boot configuration - by disabling the network interface in Device Manager when working locally.
I've recently become acutely conscious of my home network's security and how to ensure that others aren't aware of my network activity, browsing habits and secure files and folders.
I'm running a wireless home network based around a netgear router and my main PC is running Windows 7.
Can anyone tell me the most effective ways to identify intrusions on my computer (not via internet security packages, as most potential hackers would identify my internet security package and simply download one of the many thousands of well-updated programs to evade detection/prevention) and how to track them to their source or at least prevent them consistently, without relying on firewalls/antivirus (which I already have).
I'm keen not to default to my firewall/antivirus, since I think the intruder(s) knows me personally and already knows which program I use. Like I said, a quick visit to a warez site will provide thousands of programs to evade detection by any of hundreds of consumer security suites.
Any advice appreciated. I'm tech savvy enough to pursue quite in-depth options if given a guide or links to knowledge databases.
Your advice much appreciated.
