Need Advice

My computer has the protential of being hacked quite a lot due to the work I do on my computer and the clients I talk with, I knowh they are " black hat " hackers. Im not sure if this is the right section or not or if this is allowed on the forum, but I just wanted some general advice, if this is the wrong section or It's not allowed here, please just remove this thanks =), Im currently using my system is W7 64 Bit Dell, I am using as protection for my system, outpost firewall pro 7.0 version, kaspersky ( liscended version ) spybot search and destroy, malware bytes anti - malware , I have a static IP address and my ISP is virgin media, I am not the network administrator so cannot make any changes to the network sadly, I also now have " sandboxie " and IP mask, even though these are not protection! Haha, please help me would be great if a " black hat or a white hat " could tell me what I should remove and install instead to replace it, or to keep it as it is ? or what ever!.. thanks!

If you have significant risk, you should have a separate machine (logical, or physical) for your "risky" activites, versus you regular. So, you have one machine for your online banking, personal email... and a separate one for things like, I dunno, visiting BHW ;-) Now you may not want to go out and buy a new PC just for this... so look into running something like Windows 7 Virtual Server. That way you can have a virtual 2nd PC running under your Win7, it's completely isolated from your physical PC, and you can shut down and "wipe" everything that happened since you booted it every time if you want. BTW it's free... it might take some work to get the hang of it, but it's worth it. Generally a 1GB session is enough for it, without impacting your physical PC too much. You'll want at least 4 Gb on physical PC to do this, though. http://www.microsoft.com/windows/virtual-pc/
