Add Extension to Leave ads push users into obtaining questionable software

“Add Extension to Leave” is a deceptive pop-up notification [1] that typically starts targeting web browsers when some adware-type virus secretly settles down on the computer. This pop-up prevents users from quitting the website on which it is displayed and forces them to download questionable extensions without properly explaining what these extensions are and why the user needs them. In fact, these notifications may appear when infected with any potentially unwanted program that is capable of generating ads and redirect capacities. So, if you start seeing Add Extension to Leave ads on your browser, you may as well watch out for other online content that might not be as innocent as the regular and legitimate ads. Keep in mind that creators of adware programs do not hesitate collaborating with all sorts of shady third-parties or even criminals as long as such cooperation brings them money [2]. This is the key reason to keep an eye on the computer and regularly scan the system for malware that might be silently running its processes undetected. The elimination of PUPs should help remove “Add Extension to Leave” ads and other annoying symptoms of adware hijack immediately. So, get started and scan your device with a reputable antivirus tool, such as Reimage.

Add Extension to Leave virus

We should warn you that downloading extensions offered by Add Extension to Leave ads can put you in serious danger. First of all, these ads don’t usually say what extension will you install by clicking the “OK” button in the pop-up. It is highly possible that you will be simply tricked into downloading some malicious parasite on your computer which will steal your data, spy on you or work as backdoor helping other malware to enter your PC. So, you should not just stay away from these notifications but take care of “Add Extension to Leave” removal as soon as possible.

Adware distribution relies on software bundling

Indeed, software bundling is the top method creators of “Add Extension to Leave” malware employ to infiltrate computers. This technique gives them freedom in the distribution process as the malicious PUP can be attached to any popular program or file and put up for download on some software sharing website or peer-to-peer network. The users are responsible for the rest of the malware infiltration success. If they rush through the software installation, not paying close attention to what components exactly enter their computers — the infiltration is successful. However, unwanted programs can be prevented. To do that, you will simply have to opt for the Advanced installation mode when installing new software on your computer. Hopefully, these precautions will protect you from encountering “Add Extension to Leave” ads in the future.
