Sounds like you may have picked up some malware. Look at the links at the bottom of the following link and note all of the "work-at-home" type addresses that are closely associated with chablang.com: http://wikilinky.org/www.chablang.com . Also, look at this: http://www.robtex.com/dns/chablang.com.html#summary_chablang_com

REMEMBER: Never run more than 1 Firewall at a time. Never run more than 1 anti-virus/anti-spyware application in an active state at a time. More than 1 of each ~~red:may~~ interfere with one another and canel out any protection.

Do a thorough malware scan Install, update and run these programs in this order. They are all free for personal use, but some have limited functionality in the "free mode", but those are features you really don't need to find and remove the problem that you have. (~~red:Not all programs detect the same Malware.~~)

I already ran almost all of those malware scans and they didn't ' find anything. Its not like I was downloading or visiting dangerous sites on my work computer so I am really curious as to how this thing infected me,...

FINALLY I CAN SOLVE THIS PROBLEM after 3 days thingking how to get rid off it.

1. Install revo uninstaller (when you try to uinstall from control panel you 'll fail) so use this software http://www.revouninstaller.com/ 2. Uninstall Mozilla Firefox 3. Install your Mozilla Firefox again 4. tadaaaaaaaaaaaa...its solved....

I went into my addons and removed "Dynamic Media 3.0" and now have no issues. Either it's a freak thing or that fixed it. I'm not sure where I picked it up though; so, I'm crossing my fingers I won't run across it again.
