Infected is the eighth studio album by Swedish power metal band HammerFall, released on 20 May 2011 in Europe and 7 June 2011 in North America.

It was their first album produced by James Michael and the HammerFall guitarists Oscar Dronjak and Pontus Norgren.

[4] To promote the record, the song "One More Time" was released as the first official single on 6 April 2011.

[6] After considering potential legal actions and possible negative reception, the original album cover of a black biological hazard symbol[7] on a grey background was changed to the existing bloody hand.

[7] Hector does, however, appear on the "Send Me a Sign" single, and artist Samwise Didier even provides backup vocals on the main album, indicating that fans had likely not seen the last of the chivalrous mascot.
