|"Mcafee still asked me and this time, the dialog box disappears and I haven't clickes Block yet. What shall I do?"|
obviously McAfee is not doing it's job properly.
You may want to unload it and maybe use Avast Free which is much better.
Try Avast Free and get it to do a bootscan on reboot and move ALL it finds to the chest..that way you won't delete something crucial by mistake.
You will see what McAfee didn't pick up.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
