Kapersky Java Script on web pages Remains after Kapersky Deletion

more options

There is a known "issue" with Kapersky Internet Security embedding a Java script into web pages in FireFox. This is evidenced by a log event that states "Connecting to ff.kis.v2.scr.kapersky-labs.com...". See the attachment. There is a way to turn this off if you currently have a recent version of Kapersky Internet Security installed. However, I have removed all of my Kapersky IS apps, and replaced them with MacAfee. Even after deleting all of Kapersky IS apps, I am still getting the log events noted above showing up. Is there any way to block this java script from being attached to the web pages I access in FireFox without having to reinstall Kapersky IS on my system?

If all Kaspersky software is uninstalled, then there shouldn't be any fresh script injection. Perhaps it's a problem with cached files? If you haven't already, please try:

How to clear the Firefox cache

If you have a large hard drive, this might take a few minutes. If you do not see the number going down on the page, you can reload it using Ctrl+r to check progress.
