The Pop-Up — Simulated Adware Pop-Up with Rotating 1999–2003 Banner Ad Themes

At some point during a Doors 98 session, a pop-up appears. Maybe immediately. Maybe three or four minutes in. Maybe never — there is a 20% chance the session is skipped entirely. When it does fire, it presents a Windows 98-styled floating window with a period-accurate titlebar, theme-specific color palette, and a rotating carousel of six banner ad formats cycling every 3.5 seconds. The timing and the skip probability are intentional: real adware did not announce itself on a schedule.

The six rotating ad themes each reference a real and recognizable format from the early-2000s internet advertising era. Punch the Monkey was one of the most ubiquitous banner ad campaigns of the late 1990s — a Flash animation of a swinging monkey that users were invited to click at exactly the right moment to win $20 cash. Nobody ever received the $20. The prize was an email list subscription. The ad appeared on virtually every ad-supported site from 1999 to 2002 and became shorthand for the era's approach to user engagement. Free emoticons and smileys: after the rise of AIM, ICQ, and MSN Messenger, downloading an emoticon pack typically also installed a Browser Helper Object, reset the default search engine, and added a toolbar. Your PC has 14 viruses: scareware pop-ups — fake threat counts, alarming colors, urgent calls to scan now for free — remained common well into the 2010s. The scan was always instantaneous. The results were always dire. Free 3D screensaver: screensaver download ads were one of the most common adware vectors of the era. The screensaver installed cleanly. The homepage hijacker installed alongside it without asking. Download Accelerator Plus (DAP) was a real product by SpeedBit Ltd., widely distributed as free software with genuine utility — parallel-segment downloading did make files arrive faster on the throttled connections of the era. It was also a common pop-up ad target because the value proposition was real enough to click. Murica Web 5.0: a reference to the Murica Web app elsewhere on the Doors 98 desktop, itself a parody of AOL (America Online). AOL distributed installation CDs with escalating free-hour offers throughout the late 1990s and early 2000s — 100 hours, 500 hours, 1,000 hours. Receiving one by mail was essentially guaranteed for anyone with a US address. The Murica Web offer specifies 1,776 hours free. Work from home: guaranteed weekly income, testimonials from someone's mother, suspiciously round numbers. This advertising category predates the internet; the pop-up era gave it new reach and new victims. Win a free iPod: from approximately 2003 onward, the iPod replaced cash as the default promised prize for pop-up contest ads. Completing the offer wall required subscribing to several third-party services. The iPod was not awarded.

The pop-up coexists on the Doors 98 desktop with AdBot Find and Fry — a parody of Spybot Search and Destroy — which is supposed to detect and remove exactly this kind of software. Both run simultaneously on the same machine. This is also how it worked in real life: the adware shipped, the anti-adware tools responded, and users ran both for years without resolving the contradiction. The pop-up closes cleanly when dismissed and does not return for the remainder of the session.
