When I quit Firefox, after about 60 seconds it re-opens again.

Question

Almost every time I quit Firefox, it seems to close down, then it pops open again after about 60 seconds. If I quit the second time, it closes as normal. I checked to make sure it doesn't happen because the next program I am using is opening it to display some connected content. I also checked to make sure I don't have two instances of it open or something like that.

See http://kb.mozillazine.org/Firefox.exe_always_open
Do a malware check with a few malware scan programs.<br />
You need to use all programs because each detects different malware.<br />
Make sure that you update each program to get the latest version of the database.<br />
