ProADBlocks, or ProADBlocks Search, is an intrusive browser extension. It may show up in your list of browser extensions without your permission or approval. This might happen if you fall for a fake download, or if you end up interacting with a low-quality software bundle. Thankfully, ProADBlocks is not malicious. However, it is a Potentially Unwanted Program (PUP) that is known for modifying browser settings without the permission of users.
The ProADBlocks add-on often replaces the new tab page with Portal.proadblocks.com and the search engine with Feed.proadblocks.com. These changes may not be reversible unless you ensure the full removal of ProADBlocks first.
As the name of this PUP suggests, it might be advertised as an ad-blocker – in reality, however, it will not perform any tasks of this sort. This app has no useful features, and you should not allow it to continue running on your device. To remove ProADBlocks and other PUPs of this type, you should always rely on up-to-date security software. This is the best way to ensure that all intrusive files will be gone instantly.
