Yes, a keylogger is one possibility. The actual possibilities are almost
endless and you can easily get to the point - probably well-advised,
actually, if you think undetected malware may be on your computer and have
already stolen card no.s - where the only sensible course is to format and
start again! After all, just because you found nothing, doesn't by any means
mean there is nothing there! It just means the crook/s might has a really
good tool for which there are no detections (hopefully only 'yet'!). It's
the old 'can't prove a negative' problem. In most cases it doesn't matter -
but if you money is being siphoned off...
There is no doubt - it would be illogical to believe otherwise - that there
are trojans or the like that are undetectable. You can buy rootkits priced
according to whether they are detected yet or if so, by how many programs.
All very much as you would expect, too, unfortunately, ie it's not that
unusual, rather it seems unlikely because it's an uncomfortable truth we
blank out.
Still, the likelihood is, if you have malware, that it *is* detectable.
Just, if you find nothing, doesn't mean it's clean, is all I want to stress.
Otherwise, running Kaspersky Antivirus is probably the best chance of
catching any baddies you suspect you may have. Back in the days when trojan
detection was the latest thing and programs dedicated to that alone were
coming out, Kaspersky, which was not specifically targeting for trojans, was
better than all of them. That's purely because it was *that* good - and it
still is. You might find something that performs as well seeking out
trojans, but you won't find anything better and certainly not something that
also happens to find just about everything else too! It is always a good
idea to use more than one AV tool, for a second opinion - just as it is to
see more than one doctor! - but Kaspersky should be the first choice. If you
were talking about an NT system you'd want rootkit sniffers too, as they are
that much more specialised, and of which there are more every week, it
seems.
Good luck.
