Update 17.2 changed Virus's mechanics. It now restores health to enemies after its proc expires. However, it now reduces based on the enemy's current health rather than its max, making it effective even when the enemy's health is below 50% of its maximum.

Pre 17.2: Reduces maximum HP by 50%, when proc expires max HP returns but the deducted health is not returned. Enemies below 50% of their max HP lose no health from the proc.

Post 17.2: Enemy's max HP is set to half of their current HP, and their current HP is reduced by half. When the effect expires their max HP returns to normal and the HP they lost from the proc is restored.

I will attempt to re-write the page to reflect the new behavior with the correct style when I get the chance. Feel free to update it yourself using this comment as a reference, if you wish.
