After that, you may now click the remove button to get rid of the extension virus from the Chrome browser.
3. If the switch is disabled, then you will need to remove it directly from the extensions folder of the browser. To do this, first, you have to select the plugin and look at its ID as shown in the URL bar. (See the image below for an example.)
4. Open File Explorer and go to the folder where Chrome stores the Lenovo IdeaPad L340 browser extension. The default location will be at:

However, it is still necessary to exercise caution in order to keep your Lenovo IdeaPad L340 from becoming infected again. We’ve offered some safety advice and precautionary steps to help you avoid malware in the future to help you stay safe.
How to keep your Lenovo IdeaPad L340 safe
Malware infections on the Lenovo IdeaPad L340 can pose a considerable risk to both the computer and the user, especially when users are uninformed of the potential harm this malware might cause once the system is hacked.
Here are some important guidelines, safety measures, and best practices that all users should be aware of to ensure user safety and prevent further malware infections that could infect the Lenovo IdeaPad L340 and the files and data contained within.
Do not surf on unreputable websites
Taking preventative measures, such as avoiding accessing dubious websites, can dramatically minimize your risk of malware infection.
Illegal streaming platforms, pirating websites, and other sites that host unfiltered and uncontrolled adverts are examples. The advertisements displayed on these websites may result in malware infections.
Simply avoiding such websites would keep you safe from potentially hazardous adverts. This efficiently rids your computer of malware because the possibilities of downloading malware when browsing the web are lowered to zero.
Make sure Windows Defender is active
This tip may appear simple, but it is quite important because many users will overlook it. When it comes to protecting your computer, Windows Defender should always be active and activated.
Since it runs in the background, users may not check the Defender settings very often to see if it is actively safeguarding their system. A software flaw or specific computer setups can mistakenly disable Windows Defender, stopping it from detecting malware.
Even if you’re not aware of it, it’s a good idea to check the Windows Defender settings on a regular basis to ensure that your computer is always safe.
Do not open files from unknown sources
This warning has been repeated numerous times by cybersecurity pros and experts, and we cannot stress it enough: Do not open files from unknown sources, particularly if they arrive by email from unknown recipients and include potentially dangerous content.
Such approaches are frequently used by cybercriminals to deceive users into fast clicking on attachments, which typically include malware.
The same caution should be exercised when downloading unauthorized materials or torrents from the internet. The risk of malware infection from such downloads is significant, and we highly advise users to avoid them entirely.
Combining this precaution with the others outlined above can help you keep your computer safe and improve your overall internet security.
