Yesterday my PC's functionality broke down swiftly, in retrospect after I'd installed a Java update. On Gmail, Firefox brought up a suspect-looking dialogue box informing me that 'Plugin performed an illegal operation. It is strongly advised you restart Firefox'. Restarts didn't help. Never seen this before. I immediately ran AVG, which found some framer viruses (/.Z) and deleted the files. I ran SUPERAntiSpyware which reported my system as clean.
Then Excel crashed, and crashed every time I restarted and tried to do anything.
iTunes seemed to be corrupt suddenly.
So I tried to shut down, but there was no response. After leaving it for an hour or so, I powered off manually.
I now get the 'Sorry for the inconvenience...' loop as described here: http://www.annoyance...nxp/t1021829674
Safe Mode doesn't work, and neither do the other options.
I'm posting here because it seems like the work of malicious software.
Please, can anyone give me some advice?
