The ArchimedesLookup application is a utility that is compatible with Mac computers only. If the ArchimedesLookup application is present on your Mac, but you do not remember installing it, it may be because this utility is distributed via low-quality free software bundles that often incorporate PUPs (Potentially Unwanted Programs) and adware programs.
The ArchimedesLookup application's goal is not to provide you with useful features but to hijack your Web browser. Once installed, the ArchimedesLookup application will gain persistence on your Mac by creating a new 'Device Profile.' This dodgy application will also make sure to apply some changes to your Web browser's settings to make sure that when you open you a new tab, you will be redirected to a site that hosts the 'Safe Finder' search engine. This is a low-quality search engine that is not likely to offer you excellent service, so you are better off avoiding it.
It is likely that the ArchimedesLookup utility also may plant advertisements on the websites that you visit to generate revenue. Since the ArchimedesLookup application has gained persistence on your Mac, it is best to remove it via a reputable anti-virus suite.
