First of all, thanks to the folks who volunteer to help the teaming masses, those yearning to be free of malware!
I have encountered Sirefef-PL [rtk] and it has rendered the PC mostly useless; google search results get redireced; and when attempting to access gmail I receive a warning about a weak certificate. The address bar shows https with a red slash through it, and the padlock icon to he left of https has a red ‘X’ through it, and I am unable to access gmail.
Ran into trouble with ComboFix, it seemed to run normally to completion, then displayed a log, but when I try to open a browser or any program for that matter, I get a message stating, “Illegal operation has been attempted on a registry key that has been marked for deletion”. Affects all files, whether a simple text file or an executable.
