|You can uninstall Firefox. Then, install SpywareBlaster. This program has a section just for Firefox. I would install it, update it, follow all instructions and leave it. SpywareBlaster is a program that is always running in the background keeping an eye on anything malicious that wants to invade your PC.|
BUT, that is not the solution, that is just a maint program. You need to run an antivirus scan after uninstalling Firefox and any spyware programs you already ran, as mentioned above in your post.
Then, when all are done and you installed SpywareBlaster, install Firefox again. BTW, I would update all programs, THEN...go into safe mode and run all programs from there. Then, when all are run from safe mode, reboot and with the newly reinstalled Firefox, open it and see if it is ok.
You can also do a system restore and go back to a point when you knew your Firefox was clean.
I suggest you do it the first way I mentioned as it is important you have SpywareBlaster. It is a free program and can be found at majorgeeks.com, or just google it.
Please let me know if this helped.
Take care, Viv
