It seems as though since the last McAfee update some Drupal sites have been receiving an antivirus alerts. This is only affecting IE users, and could be the result of the jQuery javascript library. Try replacing the /misc/jquery.js file with the lastest file. Clear the cache, and reboot. Let us know if you have found any other issues that may be causing this error.
Right click and save this file: jquery.js (version 1.2.1)
Thanks and appreciation goes out to Bill Bailey from the office of Graduate Studies for finding this so quickly!
More information about the mess created by McAfee when a flawed virus data file was distributed.

We have two Drupal domains hosted at UTO. jquery.js (version 1.2.1) worked fine on the first one. However, when we put it on the second there were problems. When editing content, the section headers on the Edit page no longer work. For example, "Input Format", "Side Content", etc. They are normally expandable/collapsible links but after applying the new jquery file there is a JavaScript object error in the browser and the links are just text.
The other issue was one particular node started redirecting to the site's home page. Weird. We rolled back to our original version of jquery and the issues went away.
Has anyone else seen this?
thanks,
Cameron
I believe that the Javascript tools module has something to do with that, although I am not certain. Try upgrading this module to the latest version, 5.x - 0.8, and see if that helps. My guess is that the JS Calendar portion, if you are even using it, is causing the error.
Hope that helps!
We are having the same problem. The expandable menus do not collapse anymore and I seem to be having an issue with TinyMCE now. When we try to edit TinyMCE I just get an empty page with a link that reads disable rich-text. We didn't have a problem unitl now. I tried to rollback the previous jsquery but that did not resolve the issue. The tinyMCE issue happens when we try to edit the profiles that use the editor. I also notice that once in a content type if we click the html button on the wysiwig editor (tinyMCE) and we edit the html, the changes are not reflected or accepted. There is no error but when the page is submitted you can see the changes did not take affect. When you go beck to edit the page (using the html icon) the changes were not accepted.
As I said earlier we have not made any changes to our environment other than installing the new jquery file. That may not be the cause but something is wrong..
Thanks
hmm, it seems that the new version of jquery actually CAUSES the problem with tinymce. Since mcafee has apparently released a patch for this issue, we should revert back to the original version of jquery, as the new one doesn't play nicely with drupal 5.x.
