Last night I was installing a software and it tried to install SEVERAL viruses on my pc that I successfully managed to stop the installation. But I got another serious threat that I want to know whether it's still there and how can I get rid of it.
When I opened the software I was trying to install, it automatically opened a new tab on my Firefox opened window and in that same instant I knew something wrong was happening. The thing is that it loaded some pages in the same tab, using a full redirection so I couldn't go back to them and it ended in a modified Google (www.google.com/"something"). The thing is that I tried to go to the download page and Firefox started telling me THAT IT DIDN'T EXIST, then I knew something heavy was going on. I used the Reset tool (about:support) and parts of the virus got lost in the process. But the thing is that even when Firefox is set to start at https://www.google.com.uy or even when I put the blank page option for starting, it ALWAYS redirects me to the page of the virus ( http://www.istartsurf.com/?type=sc&ts=1412823435&from=sky&uid=WDCXWD5000AAKX-00ERMA0_WD-WCC2EHK4239242392 ) and if I then open another tab/window without closing the main, it justs do as I configured it (home: google, new page: blank).
Since I already reset Firefox, I want to know whether I should use another mechanism (likely deleting the entire ...\AppData\Roaming\Mozilla folder) or just reinstalling Firefox? I have already passes a full scan of my PC with AVG Internet Security 2015 (found 23 virus on the virus main folder and some Windows folders) and passed Ccleaner against every Firefox component.
If I forget about adding anything, please let me know.
