This post should be moved my apologies
My first contribution will be a little tidbit I like to install this on computers where there are teenagers and children using the PC it tends to stop a lot of junk getting in by running a sandboxed browser using virtualization without running sandboxie ;)here is the info with a link hopefully it can be accessed from the UK be sure to watch the video kinda geeky and boring all the same you may find it useful
you have to register just with your email address I often use a bogus one and it will still click you through to the download page http://www.kace.com/products/freetools/secure-browser/
you can see an in depth video on it here http://www.youtube.com/watch?feature=player_detailpage&v=DCHA1t22Byk
basically install it use it and when things need cleaning hit the resize button you will see a transparent bar across the top with a barely visible garbage can in the upper right of bar going across the top click that and it will dump all the stuff that was acquired from surfing the web
The Secure Browser uses virtualization technology to provide a safer web experience to users and organizations. When using the Secure Browser any changes or malicious files inadvertently downloaded from the Internet are contained within the Secure Browser, keeping the underlying OS and computer protected from hostile changes. Any changes resulting from browser activity may be quickly and easily reset to effectively “undo” such changes and return it to its initially installed state. This makes it much easier to clean a system and bring the user back to full productivity. Secure Browsers also offer the option of specifying “white” and “black” lists to control what processes may be started or what sites may be visited. Limiting browser use to specific sites can control usage and protect from cross site scripting attacks. By specifying which sites are to be blocked, it makes it easy to keep users away from known bad sites, and thereby limit their exposure to attacks. In controlling what processes may be started, the browser will not run programs or plug-ins without permission to do so, which allows for the prevention of many attacks before they can even be initiated.

Rapidly reset any changes made during normal use back to their initial state, enabling easy recovery from infections or attacks

Set white and black lists to limit access to known good sites, or prevent access to known bad sites to further limit the risk of attack and infection
