Extra Tab opening by itself with spam not requested

more options

Every other time (or so) that I open Firefox, it shows my home page, then spontaneously, another tab opens with some type of spam....... you know, you have won this prize or "there is a problem with your registry"

which are not valid or requested.

Sometimes it happens when I open Firefox. Sometimes I have a session going and open an other tab and then it spontaneously opens the spam tab (don't know what else to call it).

It NEVER happens when I open MSIE.

Sounds like Malware on your PC.

Install, update, and run these programs in this order. They are listed in order of efficacy.
(Not all programs detect the same Malware, so you may need to run them all to solve your problem.)
These programs 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.
Note: If your Malware infection is bad enough and you are mis-directed to URL's other than what is posted, you may have to use a different PC to download these programs and use a USB stick to transfer them to the afflicted PC.
