Facebook: unexpected disconnections

I suspect you may have asked yourself those questions too, but there’s more in two heads than one, right ;)

Ah! Then you might want to block some applications that you have authorized on Facebook and that seem suspicious. The solution might be in the privacy settings.
If you have caught a virus or something on Facebook, it would be useful to learn more about it. I'm going to take a look online and I'll be back...

I also removed some applications, but oh well...
I'll see about deleting some more!

Well... I just went to take a look at the viruses lurking on Facebook, all that stuff, and all in all, these are security issues that don’t just affect Facebook, and can be addressed with standard security tools.
So, if you’re sure you’ve done several antivirus scans (including one with the trial version of Kaspersky, just to be sure, uninstall your other antivirus first), a malware scan with Malwarebytes Antimalware, for example, then it’s better to post this topic on the Virus/security forum of this site. There are experts who can take the time to resolve your issue if it’s more security-related.

Okay, thank you, I'll look into the appropriate section then :)

Have a good evening!

Good evening too, sorry for not helping you more...
And with your account on someone else's PC? Your problem is going to haunt me :P
