Problems with 15.rewardinglocker.com taking over your browser or flooding pages with loud pop-ups and ads? Read this article — we’ll unpack what 15.rewardinglocker.com does, how it finds its way onto a device, and the exact actions to wipe it out so your browser feels normal again.
What Is 15.rewardinglocker.com?
15.rewardinglocker.com behaves like a browser hijacker and adware delivery point — software that tampers with core browser policies without clear permission. In practice, it can swap your homepage, new tab, or default search to its own endpoints and then steer you through aggressive ad redirect chains.
Although its page can look like a harmless “rewards” or service screen, its objective isn’t faster or safer browsing. During our checks, we saw behavior consistent with advertising abuse and telemetry harvesting: tracking navigation paths, inserting monetized code, and bouncing traffic through affiliate and survey pages that attempt to capture personal data or push paid subscriptions. Security vendors and scam-rating tools have also flagged the Rewardinglocker family as risky or suspicious, which aligns with our findings.

How Did I Get Affected by 15.rewardinglocker.com?
Most people don’t knowingly install anything from 15.rewardinglocker.com. It commonly appears after interacting with misleading ads, fake “You’ve won” pages, or bundled installers that quietly flip browser settings. Another frequent trigger is the web push notification prompt — a site asks you to “Allow” to prove you’re human or to claim a reward; once allowed, the browser can be spammed with ads even when no tabs are open. We’ve also seen cases where an already-present adware extension reroutes traffic to this domain.
Below are the most common ways 15.rewardinglocker.com spreads and infects devices:
- Clicking misleading ads or fake pop-ups on unsafe websites.
- Visiting pirated video streaming services, adult pages, or illegal platforms filled with aggressive advertising.
- Downloading free software installers from unofficial sources that come bundled with adware.
- Accepting a fake CAPTCHA that tricks you into enabling notifications.
- Adding a malicious browser extension designed to inject ads.
- Already having adware installed that redirects you to 15.rewardinglocker.com automatically.
What Does 15.rewardinglocker.com Do?
From our analysis, the 15.rewardinglocker.com variant participates in a “reward” scam flow that hijacks navigation and ad surfaces. It can replace your default search, home, and new-tab settings; aggressively open new pages; and pester you with push notifications that mimic Google/Amazon/Apple giveaway messages. On Windows, some builds create helper tasks or registry entries to restore the hijacker after a reboot, which is why it may reappear after you think you’ve removed it. On mobile browsers, it often abuses notifications and cached site data to keep the pop-ups coming back.
If your browser is affected by 15.rewardinglocker.com, you may see the following problems:
- Replaces your homepage, new tab page, and default search engine with 15.rewardinglocker.com
- Redirects your searches through shady websites or paid ad networks
- Injects banners, pop-ups, and ad overlays into every site you visit
- Tracks what you do online to build an advertising profile
- Uses hidden files or browser add-ons to reinstall itself after removal
Security teams generally label 15.rewardinglocker.com a potentially unwanted program (PUP) / browser hijacker because it undermines normal browsing, floods pages with irrelevant ads, and weakens privacy by collecting usage signals. If these symptoms match what you’re seeing, it’s best to remove it now to restore stability and reduce data exposure.
How to Remove 15.rewardinglocker.com Pop-up Ads
Start with your browser: open the extensions/add-ons page and remove any entries you don’t recognize, especially those added right before the pop-ups began. Next, check your site permissions and revoke notifications from anything tied to “reward,” “giveaway,” or unknown domains — this alone often stops the background ads. After that, run a reputable anti-malware scan to detect leftovers (scheduled tasks, services, or helper files) that can silently bring the hijacker back.
When the scan completes, reset your browser to default settings to roll back every unauthorized change made by 15.rewardinglocker.com. On mobile, clear browsing data and remove notification permissions for suspicious sites. To prevent a repeat, keep your OS and browsers updated, avoid cracked or unverified installers, and be cautious with prompts that ask to “Allow” notifications just to view content or claim prizes. Following these baseline practices will block similar hijackers and keep everyday browsing fast, private, and dependable.
