I followed the instructions removing PCEU virus using combofix. Everything went well, I got the report but after restarting my laptop it won't start in the normal mode at all: it prompts me to choose normal or safe mode, I choose normal, XP logo shows and then black screen as if the log-in box to my usr account was about to show but nothing happens. I waited 5-10 mins and nothing. When I switch it off again and start in the safe mode it's ok then. What can be the problem? PS. Before removing the virus, I was able to go to the normal mode but the 'virus pceu' screen would pop up straight away; now I cannot log in to my user account at all - the screen is black. What do I do please?
