If you use a browser very often, you may see errors such as “a script is slowing your computer.”
This can happen for many reasons, but topping the list of usual suspects are security programs that attempt to determine what a Web site’s script is up to before allowing it to run.
IE chokes when attempting to run a script
Bill Brody’s copy of IE 8 would sometimes drop into first gear when running a script:
- “I’ve started experiencing an IE pop-up message: ‘IE is running a script that can slow your computer.’ It was happening to me with IE 7. I upgraded to IE 8 and it persists. The problem seemingly occurs at random. I can identify no correlates. But it’s a pain in the lower back. Any suggestions?”
For example, see MVP Vincenzo Di Russo’s item on Microsoft’s Answers Forum. The second answer on that page lists numerous excellent suggestions for troubleshooting slow scripts in IE.
Security software itself can make script execution sluggish. The software may try to “snoop” the script to see what it’s doing, bogging everything down. The slowdown gets worse if you have multiple security tools running; they may compete to monitor the script — and each other.
If you suspect that a security tool may be the problem, and you trust the Web site that’s running the script, disable any tools that specifically monitor scripts. Check your documentation for the name of the relevant script-related tool or feature and turn it off. For example, some McAfee suites call it “ScriptStopper.” In Symantec/Norton, it’s “Script Blocking.” If the slow-script problem goes away, you’ve identified the culprit.
