This apparently affected version 5.33 32 bit only. 5.34 has now been
released
And it only infected the 32bit version. So 64bit users were always ok, and
any 32bit users that are up to 5.34 are ok as well.

And according to Piriform, the code put into place was only a loader, a
'back door' so to say, and as far as they can tell no actual damaging
software ever used it. But the info it did steal was not something that one
would want spread around, although in and of itself would not be that
damaging.
