After updating to FF46 I faced few unpleasant issues. Firstly after the update AVG detected threat in Program Files(x86)\Mozilla Firefox\Updated\firefox.exe (non-existing folder as FF starts in Program Files(x86)\Mozilla Firefox\firefox.exe). Then my PC started maintenance which I couldn't stop with mouse moves as usual. CPU (System process) was on 95%. Restarting PC gave me 3 installing updates (I have all updates disabled!!!) and lastly Malwarebytes detected 3 Goobzo threats. I'm not sure if this is from same FF46 or from some of the add-ons. Hope someone could explain. I removed Goobzo virus with Malwarebytes but need to know what caused this infection.

Goobzo is a malicious browser hijacker, which will attempt to take over whatever browser you have on your computer. (https://www.symantec.com/security_response/writeup.jsp?docid=2014-070813-5420-99) In this case it attacked Firefox. I'd suggest keeping malwarebytes up to date, making sure you keep Firefox up to date (and possibly Reset Firefox, Refresh Firefox - reset add-ons and settings). I'd also strongly suggest a free update to windows 10, which has increased security over Windows 8 as well a a good bundled anti-virus in windows defender. I hope this helps!

Thank you! I made additional scan with HitmanPro and it didn't detect anything after Malwarebytes did its job. Resetting add-ons would be a problem for me as I customized most used ones including custom adding filters and keeping current queue in DownThemAll. I'm kind afraid of upgrading to Win10 after I upgraded from 8 to 8.1 and spent few hours in fear what changes I'll find. But if Goobzo returns I'd keep in mind your advices.:)
