avast! Home Edition 免費防毒軟體

Ranger

Dear Spacemen & IT站 expert, Thanks for the helpful introduction of AVAST freeware. last night after I updated my virus definition, it resulted in frequent pop-up of a VIRUS THREAT - at System32hdxotxcy.dll Trojan horse Generic4.ES. When I clicked the heal button, it replied : Requested action is not avaliable for this object. Access to the file has been denied. I could only click Ignore to continue without its pop-up appearence in the centre.Could any expert advise? or could I delete it from its location, but this seems not a good idea as it is a dll file that any improper act would worsen the situation. Thanks in advance for your help.
