Today, everything was normal. I left the PC turned on when I went to training and not a single person touched it. When I came back and opened up Firefox (and Chrome for that matter but not Internet Explorer) the home page was "http://techalpunto.net/". This has never happened before so I immediately thought of a virus. I scanned my system 3 times, removed any suspicious file I could find, tried to find the source in the control panel in the "Uninstall programs" section, fiddled with my personal Firefox settings, checked the add-ons, deleted any recent downloads, cookies, you name it and tried to reset my home page to 3 different adresses but every time I close Firefox and open it up again, I get the "http://techalpunto.net/" site on the home page. I tried googling for solutions but only found 2 relevant hits and both were topics looking for help in a language I couldn't understand, both from today and both unanswered. I tried rebooting my PC and all of the obvious stuff but nothing seems to work.
I repeat, this is not a Firefox exclusive problem because it happened in Chrome as well and I can't get rid of it there either. The reason I am looking for help here is because I only have Chrome installed for other people to use so as to not fiddle with my Firefox, which is the only browser that I use.
I would really appreciate any help given.
Thank you very much in advance.

Scan for Malware
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
Further information can be found in the Troubleshoot Firefox issues caused by malware article.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
To Reset Firefox do the following:
- Go to Firefox > Help > Troubleshooting Information.
- Click the "Reset Firefox" button.
- Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
- Firefox will open with all factory defaults applied.
Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Thank you very much. I reset Firefox and it worked. I knew of MalwareBytes but had no intention of installing it before. I decided to install it anyway now and it even found 3 trojans that my Avira couldn't.
My first instinct was to reset Firefox to it's default state but I was afraid of losing my bookmarks, cookies, site preferences etc. so I didn't even bother. Now that I saw it was my last hope, I saw there is actually a phase between clicking the "Reset Firefox" button and the action being executed. The phase explains what the button will do and asks if you agree. I did not know that and I am really happy I could keep my old stuff.
Thanks a bunch, even if my instincts were right, I wouldn't have bothered to reset Firefox just because I'd be too lazy to get every setting back to how it was.
