Recommendations

Do not follow links provided by unknown or untrusted sources.

Users should be wary of visiting Web sites of questionable integrity, especially if solicited to do so by an unfamiliar or untrusted source through email or other means.

Set web browser security to disable the execution of script code or active content.

Internet Explorer security settings may be used to disable execution of client-side scripting in the Internet Zone. This may limit exposure to this and other latent vulnerabilities in the browser.

Run all software as a nonprivileged user with minimal access rights.

All non-administrative activities should be performed as an unprivileged user with minimal access rights. This will limit the impact of vulnerabilities that may be exploited through Internet Explorer.
Microsoft has released a cumulative update for Internet Explorer to address supported versions of the browser. Fixes for Windows 98/SE/ME can be obtained through Windows Update.
