Software named Security Defender loaded and was almost impossible to delete. Is it yours?

Software popped up and offered a free scan of my computer for virus. I have good anti-virus software installed. The new program reported gobs of virus and led me to a purchase page. I could not delete it using simple means. I had to do a system restore. It then popped up on a second computer and I deleted it without opening with no problems. It appears to be something connected to Firefox. Is it?

No, Firefox has nothing to do with Security Defender.

Do a malware check with some malware scan programs. You need to scan with all programs because each program detects different malware. Make sure that you update each program to get the latest version of the database before doing a scan.
