HeruclesLookup is classified as a Possibly Unwanted Program (PUP) due to its ability to take over certain browser settings and prevent users from restoring them to their previous state. The application also has been observed to act as adware delivering unwanted advertisements to the browser it has affected.
Users will notice the effects of having HeruclesLookup present on their device almost from the moment the application is installed. Without wasting any time, HeruclesLookup will change the homepage, new tab page, and the users' Web browser's default search engine. All the affected settings will be set to open the address 'HeruclesLookup Search,' which is nothing more than a fake search engine. Indeed, as is the case with most browser hijacker applications, HeruclesLookup was created with the sole purpose of driving artificial traffic towards the promoted address of a fake search engine. By itself, HeruclesLookup Search cannot produce any search results at all as it simply lacks the functionality. Instead, it redirects any search query entered into the affected browser through search.yahoo.com, a legitimate search engine.
The application also is capable of opening new tab pages that contain unsolicited advertisements. Users could be presented with dubious offers for Potentially Unwanted Programs (PUPs), fake software updates, or landing pages for tech support tactics. It is recommended to remove the HeruclesLookup from your device as soon as you notice the first signs of its activity.
