After apologizing for blaming a Windows update for the ‘Black Screen of Death’ affecting Windows PCs, security firm Prevx said more than 50,000 users have downloaded its free fix tool in just five days.

“The black screen of death, or KSOD, occurs when users attempt to boot their PCs,” writes InformationWeek’s Paul McDougall. “In cases where the bug occurs, the user is faced with a black or blank screen and is forced to reboot. It has reportedly hit PCs running Windows 7, Vista, and Windows XP.”

“‘Following the issue of our fix, which continues to receive significant downloads, we believe that this problem is still affecting a very large number of users in a very diverse range of Windows environments,’ said Prevx CEO and chief technology officer Mel Morris, in a blog post Wednesday,” McDougall writes.
