How to remove Oollesessip.com ads

Oollesessip.com is a bogus site created by fraudsters to spam users with pop-ups

Oollesessip.com is a fraudulent website set up by crooks to dupe people into subscribing to push notifications. It employs social engineering^[1] techniques to trick people into believing that by clicking the “Allow” button, they are confirming that they are not robots and will be able to proceed.

However, users are bombarded with annoying pop-up advertisements, which may continue to appear even after the browser is closed. Furthermore, the perpetrators may use rogue advertising networks to display advertisements that lead to dangerous websites. As a result, people may unknowingly visit fraudulent websites designed to steal personal information or persuade them to download potentially unwanted programs^[2] and even malware.

Distribution methods

It's uncommon to come across fake spam sites like Oollesessip.com in search results. These sites are frequently hidden on unregulated, shady websites. Illegal streaming pages, for example, frequently contain misleading ads and sneaky redirects, as well as fake “Download” and “Play” buttons that may unexpectedly open new tabs with unrelated sites.

To avoid falling victim to scam pages, stick to well-known and trusted websites. Clicking on random links and advertisements, even if they appear to promote legitimate products and services, should be avoided. Legitimate streaming services, such as Netflix or HBO, are a safer bet, with only a small monthly subscription fee and access to a large library of content.

What is adware?

Adware^[3] is software that is supported by advertisements, resulting in an increase in commercial content such as pop-ups, banners, and redirects. This type of potentially unwanted program (PUP) is frequently distributed on freeware platforms. The owners of these pages include additional programs in their installers to monetize user activity.

Because users frequently rush through the process, they may overlook the installation of these extra files. It's critical to pay attention during installation to avoid potentially unwanted applications (PUAs). Always select “Custom” or “Advanced” installation methods and complete all steps. The most important step is to go through the file list and see if there are any unnecessary files. If this is the case, uncheck the boxes next to their names.

Stop the intrusive pop-ups

Get rid of cookies and cache

It is critical to protect your browser's privacy by clearing cookies and cache on a regular basis. Almost every website uses cookies to track user activity and may store information such as IP addresses, geolocation data, visited websites, and online purchases. These cookies can then be sold to ad networks or other third-party entities.

We recommend using a maintenance tool like FortectIntego to make this process easier. This software can automatically clear cookies and cache, as well as repair system errors, repair corrupted files, and address registry issues – especially useful after a virus infection.

Scan your system to detect adware

Even after following the previous steps, if you are still seeing an excessive amount of commercial content, such as pop-ups, banners, surveys, and unexpected redirects to unknown websites, your computer may be infected with adware.

PUPs are frequently disguised as seemingly useful tools, making it difficult to determine which specific application is causing the problem. Our recommendation is to use anti-malware software such as SpyHunterCombo Cleaner or MalwarebytesMalwarebytes, which can automatically scan your device and completely remove the infection. If you prefer to handle the problem yourself, here are the instructions for Windows and macOS:

Windows 10/8:

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

Windows 7/XP:

1. Click on Windows Start > Control Panel located on the right pane (if you are Windows XP user, click on Add/Remove Programs).
2. In Control Panel, select Programs > Uninstall a program.
3. Pick the unwanted application by clicking on it once.
4. At the top, click Uninstall/Change.
5. In the confirmation prompt, pick Yes.
6. Click OK once the removal process is finished.

Mac:

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 entirely 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 suspicious entries and then delete them.
4. Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.
