Microsoft is to re-release a security update on Tuesday after internet users discovered an earlier version caused problems with Internet Explorer.
After installing the MS06-042 security bulletin, some people saw their browser crash or automatically close itself down.
The patch causes problems for people who have Internet Explorer with Service Pack 1 installed when accessing sites that use data compression and version 1.1 of the HTTP web protocols. A "hotfix" is available but customers have to contact Microsoft to install it.
According to Microsoft, the revised security bulletin, which will be released on 22 August, will automatically solve the browser issue.
?Since MS06-042 resolves a number of security vulnerabilities we recommend customers continue to deploy the update, but we do plan to revise only the IE6SP1 update and re-release the bulletin with more information by August 22nd for all IE6SP1 customers,? Microsoft said on its security blog.
