Downloaded a malicious script today. It has disabled system restore, prevents the running of all antispyware I have tried, including Spybot, Adaware, SDFix, Malware bytes. b.exe appears in WTM processes. dnif.exe sems to kick SDFix when I try to run it in Safe Mode. Ran a full antivirus check with Norton, in Safe Mode, found nothing. Norton flashed up the original 'your pc has been halted because of a malicious script' Help!!
