If you searching for a “currency” or “exchange rate” conversion tool with one of the more popular search engines, you can found a link or site like this one
This site is present the user with a lovely, extensive and complete list of currencies and exchange rates to convert from and to. All for free. The only catch being, the user gets the “result” of his calculation as … an EXE download
The download contains what some of the AV vendors refer to as Dropped:Trojan.Downloader and Trojan.Muldrop. If you are using any sort of URL filter, web-url.de and wechselkursrechner.de should maybe be part of your filter list if exe downloads make it past your perimeter otherwise.
