The Optimum Search Virus

Optimum Search is an unwanted app that is known for changing the browser’s homepage to and triggering sudden redirects to and other unfamiliar websites. The Optimum Search virus can be described as a browser hijacker and its presence in the computer is undesirable as it may cause potential security issues.

The Optimum Search Virus will redirect your searches

If you have recently realized that this app has nested itself inside your Firefox, Chrome, Edge, or another browser you prefer to use, then it is time to learn more about the specifics of this unwelcome piece of software as well about the steps you’d need to take in order to remove it.

We already mentioned that this app changes the homepage of the browser and causes automatic page redirects but this is hardly everything it does. Other things hijackers like this one are known for are replacement of the default search engine, generation of aggressive and, sometimes, misleading ads, changes in the toolbar, and even tracking of the user’s browsing history. Now, none of this may sound like a particularly serious issue, and, when examined separately, it may indeed not be. However, when combined, all of these little changes and modifications in the behavior and settings of your browser could quickly lead to more serious problems. In order to prevent those more serious problems from ever taking place, it’s advisable to remove the Optimum Search hijacker as soon as possible (and we will help you do it!).

The Optimum Search Extension

The Optimum Search Virus is a cause of a sheer irritation for the user while the latter is surfing the Internet. The Optimum Search Virus causes ads, sudden page redirects, browser changes that make it more difficult to use the browser can all be quite unpleasant to anyone who needs to use their browsing program on a regular basis. However, these aren’t the potential problems that a browser hijacker may cause we are referring to.

The real issue with apps like the Optimum Search extension isn’t what they, themselves, could do on your computer, but what online content they might expose you to. Even if the Optimum Search extension doesn’t have the ability to harm your computer, the fact that its ads and redirects may eventually land you on sites that try to scam you or that distribute Trojans, Ransomware, and other viruses is a good enough reason to uninstall the hijacker ASAP and remove all of the changes it has imposed on your browser.

A lot of the products, sites, and services that apps of the browser hijacker category promote aren’t of particularly high quality or particularly reliable. Sadly, some of the promoted sites and products may even be linked to more harmful programs such as Trojans, spyware, worms, viruses, Ransomware, and so on. Also, some of the sites you may get redirected to by Optimum Search virus may try to trick you into believing that your computer has been infected by a dangerous malware threat and that the only way to secure your system is if you download some obscure app offered by the site. Of course, this is an obvious scam, but there are many inexperienced users who may fall for it.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
