- Browser extensions are small software programs that run in your web browser and provide extra functionality.
- Malicious extensions are programs that are added to browsers to cause damage or steal data.
- Most extensions are free and easy to install, but they can also be used to display unwanted ads and collect data on your browsing habits.
If you use the Google Chrome browser a lot, you may have encountered some malicious extensions and wondered how to remove them.
Chrome is a popular browser that has millions of extensions available for download. Some extensions are legitimate and valuable, but others may be malicious.
Malicious browser extensions are usually created by cybercriminals who want to steal your data or use your computer for other illegal activities. These extensions can be installed on your browser without your knowledge, and they can do a lot of damage to your PC.
You may start experiencing problems with your Internet connection or even instability in your system. The most common malicious browser extensions are fake antivirus software or other security programs.
These programs will usually tell you that your computer is infected with viruses and offer to scan it for free. You may also be redirected to phishing sites or malware downloads without your knowledge.
Although Chrome has a built-in antivirus security feature that can prevent malicious extensions from running on your computer, sometimes it’s not enough.
What is a malicious extension in Chrome?
A malicious browser extension in Chrome is an add-on that changes your browser’s settings or displays ads on websites you visit. It may also install additional software onto your device. They are a type of malicious software that is installed on the user’s computer without their knowledge.
You can easily spot a majority of the malicious extensions, but some of the signs to look out for include:
- Excessive permission – Some extensions require access to sensitive information like browsing history or bookmarks to work properly. But others request more permissions than they need. If an extension asks for too much access, it could be trying to steal your passwords or financial data, among other things.
- Unusual behavior – If the extension does something unusual when you install it, it could be malicious. When installing any program on Windows, you’ll often see a window asking if you want this program to make changes to your computer (such as installing software). If an extension doesn’t ask permission before doing something unusual — like changing the default search engine on Chrome, you need to double-check its source.
- Suspicious source – The safest bet is always to download extensions from their official stores — in this case, the Chrome Web Store. If an extension is from an unverified source, it could be malicious.
