Re:C:\Users\All Users\Application Data\ Microsoft\CryptoRSA\MachineKeys
NOD32 reports stacks of the above files busily eating up the memory and expanding on a regular basis.
So,is it safe to delete this lot and if so,how please?

Might be worth trying to clear the SSL slate

In IE:

Tools > Internet Options and then click the Content tab and then clear SSL slate.

Off the top of my head I'd sayy it may have something to do with the browser encryption but will have a proper look for you but for now I'd leave well alone.

A quick Google suggests it could be releated to the web server application Internet Information Services so you may be able to delete it unless your machine is acting as a server.

Seems to be related to MS Net framework too!  Would be interesting if other members advised that they also have these files by the score.
I have googled the prob a little and some people advise that these files have consumed over a Gb of space.

Cant give it my full attention at the minute as I'm at work but happy to look a little further info it if you'll give me a day or two.

Thanks Mitch.

Just had a look at mine and on my Win 7 machine there are 276Kb of these files, and on my Windows Home Server which is running Internet Information Services there are 76Kb of the files.
