How to secure a compromised windows 7 PC and catch the responsible hacker in the act

i have evidence (non-technical) that my company is spying on me, not on my company pc but my private pc at home. These evidences won’t hold in court, so I am in need of technical proof. I suspect that my company has hired a hacker to monitor my PC, but I need technical evidence to proof that. And I need to find a way to block them out. Please don't ask about motivation etc. i will go into the details about the non technical side if this.

I know that this platform is very strict about “vague” questions, but I am desperate for a solution and this is the best platform I know of for security experts. So please don’t cut this question.

My Home PC: - Windows7 Premium with latest security updates.

• Firewall on with modified default settings: inbound traffic is blocked except for windows services (remoting has been disabled). Outbound Traffic is set allow windows services, Email Client (Claws Mail), latest Opera-Browser and the gaming platform Steam


• Antivirus: Avira Community Edition


• Malware Detection: Spybot search & destroy


• IPV6 has been disabled

I use my company passwords also for private services (windows logon, private email), but I changed that as of late. Now I am using lastpass with a new strong master password.

My Company-Phone (iPhone4) was granted access to my private wlan, but I had its access removed and now I am using a private Nexus 7 tablet instead. I have to logon to company servers from home in order to access work related documents and mails (part of my work), so they can see my IP quiet often.

What I need to know now are two things:

• How can I further secure my home setup (installing Linux is not an option because I am depended on windows software. And yes I tried wine)


• How can I catch the hacker “in the act” so that I have strong proof?
