PPRuNe Pop - I use Emsisofts Online Armor program, it detects all that nasty malware, blocks it, and alerts you it is trying to install.
In a large proportion of cases, OA just refuses to let it through, because it recognises it as a known nasty.
You need something like this program looking over your shoulder at all times. It's saved me a lot of angst and hours of repairing.
I got caught quite a few years ago with that nasty and notorious Russian scam mob, Winspy - and I swore I'd never get caught again.
What make it hard is that most of these malware businesses are quasi-legit, with little legal recourse to hit them with criminal charges - but they're scammers, nonetheless.
