I have no particularly important data on it and I mainly use the laptop for surfing. Now I'm going to set myself a new one in a few weeks, but I wanted to leave WIn7 on it for as long as possible…
It's the paid Avira Antivirus on it. In the worst case, could my online banking access become critical?
I would be careful with your online banking access.
To what extent? There are SMS-Tan procedures on cell phones, etc. Secured from the bank side
So despite the fact that Windows XP has ended support since 2014, and I still used Windows XP until almost the end of 2015 (including surfing the Internet) and that without antivirus and without updates. And yes, I had gotten Trojans before, namely advertising virus. It is harmless because you just get too many annoying advertisements on the Internet anyway. These can of course be deleted, unfortunately not with some advertising viruses. Such as B. In Ad by DNS Unlocker I did not even find Uninstaller. And since I didn't trust any cleaners at the time, I had to live with this virus and install more ad blockers. Fortunately, my accounts were never hacked. I can't tell you what your online bank looks like. But especially if the support is ended, I would prefer not to use Bank Online, and delete all saved passwords in your browser or reset all browsers completely.
Of course it is safe. If you don't have any rubbish on your PC and you are safely on the Internet, nothing will happen to you.
It is not dangerous. The best protection is still common sense. An additional antivirus does no harm.
So it is no problem to use Windows 7 now.
