random new tabs

[pcclan]

every so often i get new tabs that randomly open and all it is always spam and most of the time when i click on a web site from google search i get a random search engine that looks like spam. i even tried a fresh install of windows any ideas what it could be.
Edit: i am currently using ff 4 beta

No need to nuke and pave unless you like that sort of thing.

More info needed; namely your AV software.

Not enough. Get avast or avg and run it. At the very least, run Malwarebytes then spybot search and destroy. Should solve your problems.

I've yet to come across anything that MSE, followed by Malwarebytes, followed by Advanced Systemcare can't deal with - but I'm sure there'll be a first time (probably sooner rather than later)

Sounds like they are just regular popups from the pages you are opening. I think by default FF opens new windows in a tab, so if you click on a link that has an 'on load open new window' command in it (popup) it will open it in a new tab. It may not be a virus or malware at all.

when i try to search something up on google and then i click i link it loads a different search engine and everytime it's a different search engine. when i am watching a youtube video and i have anything in the search bar it will open up a new tab with a search engine with what's in the search bar. and it does it at a random basis when am watching youtube.
