A dilemma this spring for engineers at big tech companies, including Google Inc., Apple Inc. and Microsoft Corp. , shows the difficulty of protecting Internet users from hackers.

Internet-security experts crafted a fix for a previously undisclosed bug in security tools used by all modern Web browsers. But deploying the fix could break the Internet for thousands of websites.
