mysites123.com is what we call in the IT security field a browser hijacker. The name is not an exaggeration, because it really hijacks your parameters to set its own without asking for your permission first, or without you even noticing after the change is already done. By default the first two things mysites123.com modifies are your homepage and your search engine. Afterwards it could also modify the error 404 page and the welcome page in new tabs. This unwanted search engine could also add bookmarks to your browser and place strategic shortcuts so you’re forced to use mysites123.com every time.
Why they need to modify all of this all the sudden? It’s quite simple actually, mysites123.com is financed by publicity fees, meaning that advertising companies pay mysites123.com every time one of their ads is seen or clicked on. Thus, they make sure you see their page above all things and as much as possible. Besides, installing quietly onto your browsers is not everything mysites123.com does. It also makes sure that to remove it becomes almost impossible. Manually changing your browser’s configuration is mostly useless. Uninstalling the program won’t work either because Chrome and Firefox save some of their data so mysites123.com is reinstated every time.
This is why we recommend to use several free tools that will help you achieve a complete uninstall. Use them all, because some detect certain threats while others take care of the rest. If you keep having problems after using our guide, don’t hesitate to ask for help in the forum section.
