Remove Key Web
Key Web is a dodgy browser extension, which poses as a useful piece of software that introduces various features. In reality, however, its sole goal is to manipulate your browser settings nad promote 3rd-party sites. The promotion happens by replacing your default search engine and new tab with Keysearchs.com. The latter is a low-quality search service, which you should not consider using on a regular basis.
We consider Key Web to be a browser hijacker, which has the ability to take over your browser settings fully. The presence of the Key Web Hijacker on your system might prevent you from taking control over your browser configuration. The redirects that this hijacker triggers will expose you to low-quality search results, unwanted ads, and other intrusive content.
The Key Web Hijacker might have been installed because of fake ads and downloads, or via software bundles. We advise you to keep such apps away from your system by using a reputable anti-malware service at all times. This is a simple and effective measures to ensure that browser hijackers will never bother you.
