Such is the poor security situation in Windows that experts now commonly discourage users from conducting online banking or other sensitive transactions over a Windows PC. Once again, Linux live media can help you out here.
This is just comedy. Wasn't it *nix that just recently had a huge flaw in their OpenSSL stack that completely split open any operating systems or web browsers using it? I bet certain Chinese and Russian groups had fun with that one for years on end at everyone's expense...
I simply can't remember the last time a fundamental flaw was found in Windows' SSL stack.
there is nothing to say there isn't an exploitable bug in the Windows SSL stack being used right now by the groups you mentioned. It's just easier to find (& quickly fix) issues in open source gear, obviously such vulnerabilities are valuable and may well not be revealed.
