Yesjis.com ads (virus) - Free Guide

What is Yesjis.com ads?

The appearance of Yesjis.com may be caused by a browser extension or a PUA

Yesjis.com redirects users to shady websites promoting scams

Yesjis.com is thought to be a redirect virus that could be caused by a browser hijacker or adware hiding in the system. It seems to appear randomly while users are surfing the web. As a result of such infections, people can get tricked into providing personal information or downloading PUPs (potentially unwanted programs),^[1] and malware.

There are a lot of different online schemes that are meant to exploit less IT-savvy individuals. In the past years, we have seen a rise in fake antivirus warning pages, Flash Player installers, fake giveaways, and surveys. As people spend more and more time on their screens, fraudsters have taken this opportunity to spread their scams online to generate revenue.

Redirects like this can make a substantial amount of money for their creators. Every time you get redirected, crooks receive a cut. They can also make a profit with your data. Websites and web-based applications are able to track your browsing activities with various tracking technologies and in this day and age, data is the new currency.

Some users report getting redirected to a search engine with the name of websearches.club, after they type something in the search box and press Enter. It does not seem to be a legitimate search engine which is a common feature between browser hijackers. You might also notice that your homepage was changed to websearches.club. Because of this, we think there is a high chance you downloaded a rogue browser plugin.

Take care of your privacy

The main purpose of such apps is to get people to click on ads, view them, install other PUAs or malware but they can also collect browsing-related information with cookies^[2] which are small data files stored on your device. Inherently, they are not bad. They provide the ability for websites and web-based applications to personalize the user experience, for example, show relevant results.

The problem emerges when cookies can be used by bad actors. The data collected with them can be sold to third parties, advertising networks, which can use them to target you with ads even more. If the pages you visit or plugins you use do not have strong security measures in place, cookies can even be hijacked and used for malicious purposes.

Tracking technologies can collect information like your IP address, the websites you visit, links you click on, and things you purchase online. That is why it is so important to clear browsers regularly. To avoid a lengthy process, we recommend using a maintenance utility like FortectIntego. It can also fix various system errors, registry issues, corrupted files which is especially useful after a virus infection.

Search for suspicious plugins in your browser

A plugin can gain certain permissions to alter your browser settings which allow it to perform unwanted tasks. Most of the time, browser hijackers are distributed using unsafe advertising networks and shady websites but it is not unseen when users get hijacked with add-ons downloaded from official web stores. The main problem is that web store owners sometimes do not know how to identify apps that monetize user activity.

One plugin could be seen as very valuable to one user, and by another one considered to be a virus. Another reason for browser hijackers taking over users' machines is that they are very easy to produce. Fraudsters can create one code, duplicate it as much as they want, just add different names and promote these extensions on the world wide web using social engineering techniques.

The only way you can avoid being infected with browser hijackers is by doing your own research. Read the reviews, look for ratings and the number of users. You will often find that after you type a hijacker's name in the search, there are almost no results. It is not worth it to risk introducing unknown apps to your system. Choose the ones you can find plenty of information and feedback about.

If you have any extensions installed, we recommend going to your browser settings and removing them one by one, to determine if any of them are at fault for unwanted behavior. It may not be named Yesjis.com, or websearches.club. We recommend removing plugins one by one to see if you notice any difference.

Eliminate potentially unwanted applications

If you have recently installed any programs from freeware^[3] distribution sites, peer-to-peer file-sharing platforms, torrent sites, there is a big possibility that the symptoms are caused because of that. Freeware distributors often include additional programs in the installers^[4] that monetize user activity (collect data about browsing activities, generate ads, etc.)

Another dangerous thing is that PUAs are often disguised as “handy” tools so people would not notice them in the system. The program causing unwanted behavior could look like an antivirus, system optimizer, or media player that is why we suggest using professional security tools to scan your machine. SpyHunter 5Combo Cleaner and Malwarebytes can scan your machine and detect suspicious processes running in your system. Besides that, you can avoid infections as security tools give warnings about unsafe files trying to enter your system.

If you want to trust your judgment and uninstall some applications that could be responsible, you can use the guide below for Windows and Mac machines to help you. But remember, a computer without anti-malware tools is like a house without a door.

Windows

• Enter Control Panel into Windows search box and hit Enter or click on the search result.
• Under Programs, select Uninstall a program.
• From the list, find the entry of the suspicious program.
• Right-click on the application and select Uninstall.
• If User Account Control shows up, click Yes.
• Wait till the uninstallation process is complete and click OK.

macOS

1. From the menu bar, select Go > Applications.
2. In the Applications folder, look for all related entries.
3. Click on the app and drag it to Trash (or right-click and pick Move to Trash)

To fully remove an unwanted app, you need to access Application Support, LaunchAgents, and LaunchDaemons folders and delete relevant files:

1. Select Go > Go to Folder.
2. Enter /Library/Application Support and click Go or press Enter.
3. In the Application Support folder, look for any dubious entries and then delete them.
4. Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.

The best option is to get your software only from official sources because it is always the safest way. There are plenty of free and reputable software that you can choose from instead of using unsafe sources. We know it can get costly but it might save you money in the long run by not ruining your device. We suggest you follow these steps during the installation of software:

• Always choose the “Custom” or “Advanced” installation methods
• Read the Terms of Use and Privacy Policy to find out what the application will be able to do in your machine and what data will it collect
• Inspect the file list and untick the boxes next to any files that seem unrelated
