hi, today i search in google about ip/dns tracer locator whois freeware tools but unfortunately i didn't meet the tools i need and also i get many trojan , my avira didn't detect, but avast can detect it . so i hope somebody can tell me what tools name i must download.
Going back to the original question, what would probably help is exactly what purpose/function is it that you want this to do as there are many IP whois tools and they all aren't the same in how they work.
There is the firefox WorldIP add-on, but that just gives information on the site that you are actually on, it doesn't give the opportunity to pre-check an IP to see where it is located in the world. Some IP whois info only gives information on the companies headquarters location and not the actual location of the server that you may be directed to in the case of large companies.
