About the Game
Antivirus Girl is a defense shooter game where you directly control a character to install modules and defend against oncoming enemies.
Become a new inspector for the advanced antivirus ‘Sentinel’ and protect computers from external threats.
First, deploy modules at key locations to set up the movement path. Once inspection begins, you must scan the files incoming from the external network.
If a file is safe, let it pass through; if it is malware, destroy it immediately. Malware with various unique characteristics will continuously threaten the client’s system. Flexible adaptability to the situation is essential!
Sentinel consists of various departments such as Scan, Clean, and Analysis. What kind of stories will unfold with the agents there?

Official update history
Hello, Antivirus Girl has been updated to version 1.0.1d.
Difficulty Improvements
If you fail the hacking minigame during a boss fight, your next hacking attempt will always succeed.
Evading now cancels the attack animation and triggers immediately.
If you keep failing at certain sections of 4-1 and 4-2, you can now skip them.
The 3-star requirement for 4-3 has been relaxed.
Bug Fixes
Fixed an issue that occurred when trying to set a mouse click as a new key binding.
Fixed an issue where sound could occasionally still be heard during the Trojan Horse boss fight even with sound turned off.
Fixed an issue where enemy spawn locations were sometimes not displayed on the minimap.
Fixed an issue that occurred when returning to base or exiting to the title screen during module installation.
Upcoming Updates
A new game mode, "DDoS Attack", is in the works. The update is expected in late September.
Thank you to everyone who plays the game.
Hello! Here are the changes included in today's 1.0.1b update.
This notice also covers the fixes from version 1.0.0n, released a few days ago.
Bug Fixes
Fixed a bug where the game would occasionally not end even after victory.
Added new elements to the minimap (enemy spawn entrances, memory leak zones).
Improved the visibility of the warning effect for incoming airborne enemies.
Fixed an error where Power and Star rewards did not match.
Fixed an error allowing duplicate summons of Tier 4 towers.
Fixed reversed stereo sound directions.
Fixed an issue where the Trojan Horse would spawn too close to the entrance.
Fixed a wave counter display bug in Stage 4-6.
Fixed a bug where damage from the Sniper and Sniper 2 towers was being applied multiple times.
Fixed various text display errors.
Balance Changes
Since the Sniper tower bug fix reduced its single-target damage, its base attack power has been increased and a small amount of area damage has been added.
Sentinel now grants 3 additional Power each time its version is upgraded.
Slightly reduced the health of Dropper and Dropper Minions.
Improved the overall pacing of Stage 1-2.
Reduced the number of enemies rushing in at the start of the 2-2 wave.
Slightly reduced enemy counts and increased spawn intervals in Stages 3-2, 3-3, and 3-5.
Lowered the difficulty of the moving laser section and spike trap section in Stage 4-1, and relaxed the 3-Star requirements.
Reduced tracking speed and the number of Watchers in Stage 4-2.
Reduced enemy health by 1 in the Stage 4-6 minigame.
Upcoming Updates
New skills for Kiana and Lina are in the works.
Tier 4 towers don't quite feel powerful enough in terms of effects and performance, so we plan to improve them.
We're also preparing a new game mode with its own set of rules: DDoS Attack Mode.
We'll do our best to release these updates within Q3.
Thank you for playing!
