Hello. This is my first post in this forum.
My problem is as follows:
Today I started my computer up as usual, first thing that opened was Skype, it crashed, had to restart, and then weird stuff started happening. Firstly, the booting time increased in length, particularly after I press on the account icon. The screen doesn't load as fast as it always had, all I can see at the beginning is the pointer (the rest is all black), and only after a rather long while does everything else start to appear. I've also noticed that the toolbars I had on the taskbar have dissappeared.
Secondly, and perhaps this is unrelated but I don't think so, an error message pops up once it finally loads the desktop, saying something like "dropbox.exe - bad image ... [route]/security.dll is an invalid file that cannot be run by windows or is damaged..." or a message along those lines (if you want me to deliver the whole text I will write it down the next time I reboot, thing is, I'll have to translate it from Spanish, so it might not be the exact same thing you would get in English). One of the times I rebooted it to see if just turning it on and off again would make this go away I got the "This copy of Windows is not genuine" message (it is genuine). This hasn't happened again, luckily.
Since these two problems are happening at the same time I imagine they might be somehow related, but I'm unsure.
Hopefully it won't be too hard to sort this out? Thanks.
