Shaun Hammond Business Solutions Limited released Antivirus Survivors 2003 Professional for PC on Steam on September 28. The game is a Vampire Survivors-like roguelike shooter set inside an infected family computer, where players move a mouse cursor to defeat viruses and adware. A single run lasts roughly 30 to 40 minutes. Players collect experience points and keys by moving through folders, then double-click files to upgrade weapons and abilities. The game has 24 weapon types, including Pinball, Solitaire, and Firewall, each modifiable with dedicated Drivers. It also has 33 file types and 62 plugin types. Suspicious advertisements and warning pop-ups appear during combat and must be cleared while avoiding enemies. The level-up screen is styled as a document-creation-software window. Difficulty spans five levels, from Protocol I to V. A free demo released in February 2026 holds an Overwhelmingly Positive rating on Steam, with 98 percent of 614 reviews positive.
Shaun Hammond developed the game almost entirely alone. He has worked in the industry for more than 10 years, starting at New Blood Interactive in 2014, then at RocketWerkz and Usual Suspects Studios, with credits on Stationeers, ICARUS, and It's Only Money. A July 14 update announcement said he brought in outside help for animation and localization for the character Virry.
Automaton described the result as "a constantly noisy hell desktop," and both the early-internet visuals and the soundtrack drew praise. Game Spark listed the full feature set:
