Avast this week released an update to its antivirus software that falsely identified hundreds of innocent files as Trojans – then fixed the situation five and a half hours later.

“Falsely labeled as malware were programs from Adobe, Realtek, sound card drivers, and various media players, among others, according to a blog post on the Avast Support Center,” writes CNET News’ Elinor Mills.

“The errant update had been issued around 12:15am GMT,” Mills writes. “A new update was issued at 5:50am GMT that corrected the problem… The software was identifying the good files as the Win32:Delf-MZG Trojan, according to Avast.”
