Rumpel,
Sality was very nasty, umm, I believe, devastative would be the better word to describe it since it may have been removed yet it leaves your computer damaged due to file infections.
Hearing the word about messenger.exe and jqsnotify.exe being oddly gone could be a possible sign of spread of the infection. Anyhow, it would always be best to have a second opinion from someone else so I guess, it would better if we consider waiting for other ideas about this.
Thank you for your help.
PS: Sorry, I can't keep up with the time. Good night to everyone.
