Remove ValidManager
ValidManager is a Potentially Unwanted Program (PUP,) and it is not dangerous. According to posts from users wondering what ValidManager is, it seems that this app only affects Mac systems. Despite what its name says, you can be sure that it has nothing to do with any sort of management, and it is not a 'valid' app at all. This software exists with the sole purpose of manipulating your browser settings. The changes it introduces are not a threat, but they are likely to ruin your Web browsing experience. For example, may make sure that your new tab page and search service redirect you to 3rd-party, unknown sites.
While we have no information about the sites that ValidManager promotes, you can be sure that they are not useful. Typically, Mac PUPs like this one tend to promote low-quality search engine. What are the characteristics of a low-quality search engine? For starters, it may contain extra ads that will bother you when you try to search for anything. Furthermore, ValidManager's sites may also show sponsored results on top, and try to mislead you into following unreliable links.
Needless to say, the behavior of ValidManager is very intrusive and annoying. If you notice this PUP on your Mac, you should prioritize removing it. Trying to do this manually is not a good idea – you will not be able to identify and delete all files. Instead, you should handle this task with the help of an up-to-date Mac security tool. A full system scan should help you identify and eradicate PUPs like ValidManager once and for all.
To avoid encountering ValidManager or similar apps again, you should keep your Mac protected at all times. Also, avoid downloading files and installers from unknown sources.
