Actually, your computer must have been infected by isearch.brothersoft.com redirect virus when the signs you mentioned above appear on your computer. So what is isearch.brothersoft.com redirect virus? It is a type of computer virus that can hijack users’ web browsers to its own domain or other unwanted websites. Once installed on your computer, this redirect virus will first change your registry entries, so that it can be launched every time the Windows logs on.

Then, it will modify your browser settings and DNS settings, in order to take control over your browser. You may soon notice that your default homepage and search engine have been replaced by isearch.brothersoft.com without any permission. When you run your browser, you will be forced to visit its own domain page. If you use the search engine provided by the page to search for something, the search results may be always redirected to some unknown websites. Please note that you should not trust all content provided by the search engine, especially the ads and the sponsored links. Otherwise, you may be tricked into some useless or fake products or services. This redirect virus will also manage to add other toolbars onto your browser, which could collect your search terms and further deliver more precise ads to you. No doubt, isearch.brothersoft.com redirect virus can pose a threat to your computer security & personal information. So, it is highly recommended that it be removed timely.

How Does the Redirect Virus Enter Your PC?
Isearch.brothersoft.com redirect virus always enters a targeted computer secretly. One of the most common ways is coming bundled with various freeware or freeware downloaded from the Internet. When you download such software and install it on your computer, this redirect virus may be installed as well. So, you should always opt for Custom installation and don’t agree to install any optional program. Besides, isearch.brothersoft.com redirect virus can be distributed by Trojan horse which always pretends to be a legitimate file or application. For example, the redirect virus can come together with a Trojan horse which disguises itself as a harmless email attachment. Generally, you may be sent an email which has an attachment (actually the attachment is disguised by a Trojan horse). When you open or download the attachment, the Trojan horse is downloaded, too. And the redirect virus can get itself installed on your computer then. Another common way to attack your computer is via hacked websites. Websites hacked by cyber hackers are not safe to browse, for you may unwittingly download the redirect virus onto your PC when careless clicking on some links or pop-up windows. Thus, you should use extra caution in your daily online life.
