Shaun Hammond Business Solutions released the post-apocalyptic shooter *Antivirus Survivors 2003 Professional* for PC (Steam) on September 28. Just one day after its release, the game has already earned an “Overwhelmingly Positive” rating on Steam.
A highly anticipated title with an “Overwhelmingly Positive” free demo
*Antivirus Survivors 2003 Professional* is a survival shooter featuring visuals reminiscent of early 2000s operating systems, from the menu to the combat screen.
Players control a mouse-cursor-shaped craft as they battle incoming viruses. During combat, players click on various program files scattered across the map to install and extract them, upgrading their weapons and craft while keeping an eye out for windows that flood the screen.
This game features memorable graphics, such as a bouncing DVD logo and card designs that look like they could appear in Solitaire. A new free demo version was released in February 2026, and it has also received “overwhelmingly positive” reviews.
