Microsoft is releasing an update to its Internet Explorer browser to fix a security problem that could expose personal computers to hacking attacks.

A permanent repair to the security flaw will be released Friday.

Microsoft Corp. began offering a temporary patch for the problem Wednesday on a part of its website set up for technical issues.

The permanent solution to the problem will be automatically installed on PCs running on Microsoft's Windows operating system if the machine is set up to receive important updates.

The temporary repair requires clicking on a link.

Microsoft says most PC users weren't affected by the security bug.

But the potential for trouble prompted a German technology agency to advise using other browsers besides Internet Explorer.
