Hello Alpha32,
You really do need to update
all your applications including Adobe as it looks like that has been evoked by yet another exploit.Having known holes in your security is like a human playing Russian roulette, You might get lucky a few times but ultimatley you will catch a bullet sooner later!
Hotmail webpage does display rotating 3rd party banner ads. Hotmail might be secure but unfortunetly from time to time those banner ads are serving up exploit code
AcroRd32.exe is only legitimatly evoked when attempting to view a PDF document via your browser. No online PDF document usage in the same session as seeing that process in memory = Not legitimate usage(immediate cause for concern).
Have just checked in our database to see the signature producing that detection but it was based soley at targeting a packer string so the file could be a number of things.
The fact we detect the file when sniffing it on a fullscan means automatically that if it had attempted to load into memory or was already memory resident either our realtimer Protection Module would have blocked or our quick scan would have picked it up.
In the absense of either detection i would say that the file has been written to disk probaly downloaded by one your exploits but it failed to be loaded into memory where it would have been able to carry out it operations.
That said it would be prudent to have your computer looked over just to make sure that nothing else has sneeked past us, It does happen occaisionally as no blacklisting software will know all malicious code that is created.
