What is

Whether has hijacked your homepage or your New Tab page – or both – you cannot ignore this browser hijacker. In most cases, users acquire this suspicious hijacker by installing an extension that goes by the name “Speed Tester BRS.” Both the hijacker and the extension were created by Polarity Technologies Ltd. Have you downloaded the extension from an official website or the Chrome web store (if you are a Google Chrome user)? If you have, we would appreciate it if you shared information about this source in the comments section because, at the time of research, official installers did not exist. Of course, it does not mean that the hijacker is not spreading if an official installer does not exist. In fact, even if it existed, it is much more likely that users would use third-party sources. If you have downloaded the extension/hijacker using a third-party installer, it is very possible that other infections exist, and if they do, you must remove them immediately. Hopefully, that is not something you have to worry about because deleting is important as well.test
