clean site blocked by eset - virus malware removed

I have 3 sites that were attacked with a trojan.
I backed up the first one with its original files and transfered to another hosting.
everything is ok, and the files are clean.
however eset and other security systems on other computers are still bloking the site.
I sent a report to google and to eset asking to remove the block, however I can't get to all secuity sysmtems.

Any suggestions on how to unblock this site?
