Why am I seeing the Lp.macapps-optimize.club pop-up ads?
You are seeing the Lp.macapps-optimize.club pop-up ads because you are either infected with adware or another web site is redirecting you to them.
This guide was written to help Mac users remove malware from their devices, so if you’re just looking for a way to block the Lp.macapps-optimize.club redirect on a specific site, you can use a free browser extension like Adblock.
When it comes to adware, these malicious programs are bundled with other free software that you download off of the Internet. Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed adware without your knowledge.
Here are a few typical signs that you have adware on your system:
- Advertisements appear in places they shouldn’t be.
- Your web browser’s homepage has mysteriously changed without your permission.
- Web pages that you typically visit are not displaying properly.
- Website links redirect to sites different from what you expected.
- Browser popups appear which recommend fake updates or other software.
- Other unwanted programs might get installed without your knowledge.
You should always pay attention when installing software because often, a software installer includes optional installs. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.
To check your computer for adware and remove it for free, please use the guide below.
