In Antivirus Survivors 2003 Professional, understanding how to adjust run difficulty is essential for clearing runs and farming meta-progression currency. The game separates difficulty into two distinct systems: Protocols and Policies. While Protocols define the base difficulty of the environment, Policies act as specialized run modifiers that impose specific rules or restrictions.
This guide explains how the Policy system works, how it interacts with Protocols and Domain Policies, and which specific Policies have been confirmed through official game releases and community documentation.
How Protocols Differ From Policies
To set up a run properly, players must distinguish between Protocols and Policies. The official game overview and guide documentation define their separate roles:
- Protocols (I through V): The five standard difficulty folders. Protocol I is the baseline entry tier, while Protocol V represents the extreme endgame ladder designed around heavy meta-progression. Protocols govern base enemy scaling, run pacing, and base BeanZ rewards.
- Policies (15 total in the full game): Independent challenge modifiers that bolt onto a run. According to developer Shaun Hammond's release announcements, a Policy can be applied to any Protocol difficulty. Rather than simply raising enemy numbers, Policies fundamentally alter rules, inventory limits, or player capabilities.
While Protocols decide the baseline stats of your opponents, Policies dictate the exact constraints you must navigate during your 30- to 40-minute desktop cleanup.
Standard Policies vs. Domain Policies
When configuring a run in the folder selection interface, you will encounter standard Policies as well as advanced Domain Policies.
Gameplay recordings and player testing show that regular Policies can be selected on unlocked tiers to modify standard runs and provide currency multipliers (such as a 1.40x BeanZ bonus). Meanwhile, the in-game interface specifies that Domain Policies require you to complete three different policies on Protocol I or higher before they become accessible.
Players on the Steam community forums note that Domain Policies impose far harsher, build-defining constraints. For instance, forum discussions highlight that running Domain Policies can completely alter character viability, such as forcing a pacifist structure or halving run timers, which drastically limits how many weapon upgrades you can acquire before confronting bosses.
Confirmed Policies and Known Modifiers
The full commercial release includes 15 Policies. While developers have not published a single consolidated changelog detailing all 15 rules side-by-side, public Steam achievements, developer posts, and gameplay streams confirm several specific Policies by name and function:
| Policy Name | Source / Documentation | Confirmed Rules & Effects |
|---|---|---|
| Legacy Hardware | Gameplay Stream & Steam Achievement | Enemies move 40% faster and deal 20% more damage. Awards a 1.40x BeanZ multiplier. Required for the "Legacy Hardware V" achievement. |
| Bloatware | Gameplay Stream & Steam Achievement | Significantly increases enemy spawn density across waves. Tied to the "Bloatware V" achievement. |
| Kiosk Mode | Steam Community & Achievements | A restrictive challenge (often referred to by players as pacifist mode) where standard weapons are unavailable, forcing reliance on utility items, damage procs, or external files. |
| Halved Time / Timer Policy | Steam Community Bug Reports | Greatly reduces available stage time, drastically shrinking the window to harvest XP, open folders, and collect level 16 weapon drivers before bosses. |
| Bad Sector | Steam Achievement | Confirmed challenge modifier required for the "Bad Sector V" achievement on Protocol V. |
| Low Memory | Steam Achievement | Confirmed challenge modifier required for the "Low Memory V" achievement on Protocol V. |
| Blue Screen Imminent | Steam Achievement | High-stakes survival modifier required for the "Blue Screen Imminent V" achievement. |
| Natasha's Wrath | Steam Community & Achievement | Aggressive challenge modifier required for the "Natasha's Wrath V" achievement. |
| Fatal Exception | Steam Achievement | Extreme failure-state challenge modifier required for the "Fatal Exception V" achievement. |
| Extended Support | Steam Achievement | Progression modifier required for the "Extended Support V" achievement on Protocol V. |
| Read Only | Wiki Progression Records | Named challenge modifier cataloged in release achievement trackers. |
Note: Specific mechanic breakdowns for remaining unlisted launch Policies have not yet been fully documented by the developer in public patch notes.
Boss Encounters Under Policy Constraints
Applying Policies heavily impacts how you approach the game's six bosses and mini-bosses. In standard runs, players encounter Plus! variations of standard viruses (such as Ask Jeeves parodies like Questions Plus, or Internet Crawler Plus) at mid-round intervals, culminating in final stage bosses like the Recycling Bin or the Spinning Beach Ball of Death.
Official patch notes state that bosses feature distinct attack patterns: they shoot projectiles, charge across the screen, throw objects, and enter temporary windows of invulnerability.
When playing under restrictive Policies:
- In speed-constrained setups like Legacy Hardware, boss charges and projectile speeds leave significantly smaller dodge windows, making movement stats (Cursor Speed) and defensive packet loss crucial.
- In weapon-limiting modes like Kiosk Mode, players on community forums point out that standard boss DPS fails completely. Survival hinges on finding interactive desktop files—such as dragging Vapor.exe bombs, picking up temporary Criminal program triggers, or destroying sub-files—to deal damage during the final stage.
- Bosses like the Recycling Bin heal by consuming discarded file packets. When Policies reduce your total damage output, failing to stand in the correct zone to intercept healing packets can make the battle unwinnable before system corruption claims your run.
Strategy: Progression and Unlocking Policies
If you are aiming to complete every Policy achievement and conquer Protocol V, progression should follow an incremental path:
- Farm BeanZ on Stable Protocols: Do not jump straight into high-tier Protocols with active Policies. Payouts for meta-progression currency (BeanZ) scale with tier completions. Clear Protocol I and II comfortably to bank BeanZ into permanent Ranks (like Max HP, Processing Speed, and Weapon Power).
- Clear Three Base Policies First: Because Domain Policies remain locked until you beat three separate standard Policies on Protocol I or higher, prioritize manageable modifiers like Legacy Hardware on lower tiers before touching extreme modifiers.
- Align Drivers with Active Modifiers: Reaching level 16 with a weapon unlocks Drivers that alter its behavior (such as adding wall-bounces or split projectiles). If a Policy limits your weapon count or spawn time, pick starting tools whose drivers offer immediate area coverage or passive status ticks (Heat or Lag).
- Inspect the Safe Folder Shop: Safe Folders provide a respite between round waves where you can upgrade tools, manage leftover keys at the keyBuy counter, and buy health recoveries. Under restrictive Policies, tailoring your build in the shop is critical to surviving the next folder jump.
