Hello. I wanted to change my browser homepage to Google search, but I could not do it! I am using Mozilla Firefox. I have reset my homepage, but after I had launched Firefox today, I saw that mysearch123.com is still on Firefox. What is the problem?
What is known about mysearch123.com?
Mysearch123.com is a browser hijacker, which may land on each of your web browsers and try to make you visit affiliate or sponsored websites. Be careful because this search is sponsored by third parties and used solely for marketing purposes. Therefore, you should never believe that it will provide you with any beneficial service because what it is going to do is to deliver altered search results, and display sponsored advertisements, track you, use PC’s resources, and so on. Thus, if you want to prevent all these issues, you should stay away from mysearch123.com virus. For that, you should investigate every freeware before downloading it and later perform its installation as carefully as possible. We recommend doing so because this search site is commonly distributed via software packages, e.g. attached to other freeware and shareware as an ‘optional download’.

As soon as mysearch123.com settles on your web browser, a serious havoc may start during each of your browsing sessions. You may notice that your web browser runs slower than it used to because this search tends to use PC’s resources. Besides, the amount of suspicious apps, such as YoutubeAdBlocker, CouponDropDown, Linkey, and many others may increase on a daily basis because it may increase security vulnerabilities and help other PUPs infiltrate your machine. Even more, mysearch123.com may appear as your default start page, search provider, a new tab, and may continuously present you with alleged search results. Be careful because it may provide you with sponsored links and advertisements clicking on which may lead to serious issues, such as mysearch123.com redirects to suspicious/unsafe/malicious third party websites. By the way, the presence of this search provider also indicates the fact that your privacy may also be in danger. It seems that it uses tracking cookies for investigating user’s web browsing habits (preferred websites, search terms, data entered in certain websites, clicks, IP address, PC’s location, and so on). Thus, if you want to prevent virus infiltration, privacy-related issues, and similar things, get rid of mysearch123.com virus without any delay. The best way to do that is to perform a full system scan with a reputable anti-spyware, such as FortectIntego (compatible with Windows OS) or FortectIntego (compatible with Windows and Mac OS X).
How can mysearch123.com hijack my computer?
Usually, mysearch123.com spreads bundled with the most popular free software, for example, download managers, PDF creators, media players, popular games and so on. Besides, software bundles that contain the hijacker are commonly promoted on such websites as download.com, soft32.com, cnet.com, softonic.com, and so on. It means that regardless the trustworthiness of the download source and the freeware itself, you should check it before installing anyway. Make sure that you opt for and Advanced or Custom installation mode, which in comparison with Quick or Basic installation is expanded and should disclose all ‘additional components’. Then make sure that you analyse each check box carefully and unmark ticks that have been pre-checked for you.

How to remove this browser hijacker?
If mysearch123.com virus has already taken over your web browser, you should eliminate it without any delay.
