Malware To Blame For Windows Black Screen Glitch

It appears that malware, not Microsoft's security update, is the root of an issue being dubbed the "Black Screen of Death."

Windows 7 users claim that their screen turns completely black soon after being logged in.

The issue also affects Vista and XP, according to reports.

Software firm Prevx last month said that Microsoft's automatic software update was to blame for the issue, but has since retracted that statement, adding that it apologizes "for any inconvenience" caused by earlier claims.

"Having narrowed down a specific trigger for this condition we've done quite a bit of testing and re-testing on the recent Windows patches including KB976098 and KB915597 as referred to in our previous blog," said Prevx.

"Since more specifically narrowing down the cause we have been able to exonerate these patches from being a contributory factor."

In a blog posting, Microsoft said it "found that our November Security Updates are not making changes to the system that these reports say are responsible for these issues".

Yesterday, Prevx issued a fix for the problem that it claims may affect millions of people.

"Users have resorted to reloading Windows as a last ditch effort to fix the problem," said Prevx's Dave Kennerley in a recent blog post.

"We hope we can help a good many of you avoid the need to reload."
