<<My current security suite is about to expire - ESET Nod32 - so I'm looking to find something which will actually stop the above from getting onto my system in the first place.>>
You cannot rely on any one item...AV, firewall, other malware-defense program...to protect a system from today's malware. Cold and simple truth.
Combine that with the fact that...no matter how well-protected a system might be...it's really the user who is the weak link in protecting a system. A user who doesn't understand the importance of safe surfing...will undo any program that may have been installed for protective purposes.
FWIW: Windows Security Alert...is only one of a truckload of such programs. To be concerned with it...seems overly simplistic to me.
Sometime...you might take a look at the BC stable of current removal guides for this and similar types of malware, http://www.bleepingcomputer.com/forums/forum55.html
There is not necessarily any defense known today...for what may come our way tomorrow or the future. All defense measures that users take...are pretty much reactive in developnebt. That means that...we come up with ways of defeating/overcoming it after it has been recognized as something new that is not necessarily neutralized by the "old cures".
In spite of the rhetoric used by vendors/developers to make users think otherwise...it's a very uphill battle, which is why our malware forums are so overworked with malwaare situations.
When I was in the Army (eons ago), I took a course on physical security, as part of my site security responsibilities. The most basic precept that I remember being stressed...is that...it's impossible...yes, impossible...to prevent someone who wants access from gaining such, provided he/she has sufficient time and opportunity.
I tend to think of malware in the same way...which is why safe surfing practices are so important. Increase the chances by ignoring such...and you increase the opportunities to beocme infected, IMO.
I don't know anything about malware, it's not my cup of tea and my knowledge is pretty sparse...but you may also want to visit AV, Firewall, Privacy Products and Protection Methods.Edit: I moved your post to the above forum
