'The operation has been cancelled due to restrictions in effect on this computer' prompts when firefox is started.
When I tried to open Firefox, it displayed a pop-up saying that 'The operation has been canceled due to the restrictions in effect on this computer. Please contact system administrator'. Even if I logged in as system administrator and tried to start Firefox, it showed me the same pop-up. The problem started from today morning. Yesterday, I was using Firefox and it worked for me. But for quite few days even though if I closed the window it was still running. Next time if I need to start Firefox, I need to close it from the Task manager and then need to start it. Not sure how to fix this problem. Now, I uninstall ed the older version (3.5.0 not sure) and updated with 3.6.3. Then also it shows me the same pop-up.
This happened
Not sure how often

Do a malware check with a few malware scan programs. You need to use all programs because each detects different malware.
