This page aims to help you remove Str-search.com “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Our main goal within the article that you are about to read on this page is to present you with important and useful information on the topic of Str-search.com – a browser hijacker/browser redirect piece of software. This application, though annoying and unwanted, can’t do malicious things like encrypt your data and ask for a ransom payment like Ransomware programs do or corrupt your machine’s system like a lot of Trojans are able to. Instead, it’s primary function is to show different advertising materials on your screen and page-redirect you while you are using your browser. Normally, the browser hijackers achieve that by attaching themselves to Chrome, Firefox, Edge, Safari or other browsers and replacing different components of the browser with their own custom ones. This could include the search engine tool used as the default searching service of the browser, the homepage web address as well as the address of the new-tab page.

Str-search.com Browser Redirect

The toolbar may also get affected by the hijacker if this would increase the number of ads that would get shown on your screen. All in all, this isn’t really something that would directly endanger anything in your computer but it is also not a type of activity that you should tolerate. Aside from the sheer annoyance that browser hijackers like Str-search.com are bound to bring, you should also not forget that not all ads on the Internet are safe to interact with. The problem is that even if you deliberately and conscientiously try to avoid clicking on the adverts, you may still accidentally interact with some of them and this, in turn, could expose your system to various hazards, among which may be Trojans, Ransomware encryption-programs, Rootkits, Worms and many more. All things considered, the removal of Str-search.com is the best option you have in such a situation which is why we suggest that you have a look at the following uninstallation guidelines for Str-search.com.

What about avoiding hijackers in the future

The majority of users do not actually realize how such an app may have gotten installed inside their systems due to the rather sneaky distribution techniques that are used to get hijackers installed onto more computers. A very commonly used method of getting software like Str-search.com onto more and more machines is the use of installation bundles – when this method is employed, the browser hijacker is combined with other software and distributed in a bundle alongside it. The bundle usually includes a main program (normally some free one) and some added components that are typically under an opt-out clause. This means that if you do not want to get the bonus element installed, you’d need to manually opt-out of its installation from within Advanced menu of the setup wizard. Most users forget about this step or simply ignore its importance and that is how they could get a hijacker installed if any of the bonus elements is one such hijacker app. It is, therefore, very important to always check for bundled installs and opt-out of them if you think you may not need or want them becoming part of your system.
