I think that you are only guessing that it did nothing. It was
evidently executing from the temp directory, so it could have
done more than just a failed attempt to "phone home".
If the 'dnld' part of the filename is any indication, it appears
that the program was intending to download (and probably
execute) another of its components.
it was a program that hided in my temp directory that asked
acces to the internet I removed it manualy
It would still be advisable to scan for Adware, Spyware, and other
Malware. It probably used an exploit of a vulnerability that you
should patch also. If you scan for the suggested types of programs,
you might be able to determine which vulnerabilities were used
by researching the write-ups about the programs found by the scans.
No need to apologize ~ your English isn't perfect (not that I would
know if it were), but it is by far not the worst I have read here.
