The “Potential Threat Warning” pop-up is a deceptive browser-style alert that tries to scare users with claims about a trojan or worm, often using names like e.tre456_worm_Windows and Rahsecure.com. It is designed to look urgent, but it is not a trustworthy Windows security message.
The warning reads as follows: “Potential Threat Warning – Your PC may have been exposed to a trojan virus (e.tre456_worm_Windows).We recommend running a scan to check for potential threats. SECURITY NOTICE Your PC may have been exposed to a trojan virus (e.tre456_worm_Windows). A scan is recommended.” These warnings commonly push a Scan Now button, which can lead to unwanted software, fake support pages, or further prompts. Some users see the alert reappear after restarting, during games, or inside normal browsing sessions, making the problem feel like a real infection.

OFFERIn many cases, the cause is tied to browser notifications, suspicious ads, or unwanted programs already present on the computer. A related sign is a default search engine changing by itself, which may point to a browser hijacker or another unwanted component.
Users should avoid clicking the warning and should not call any number or install anything it recommends. If manual cleanup feels confusing, a reputable antivirus such as SpyHunter 5 can help detect and remove unwanted programs and possible malware.
