Hello,
yesterday, juste when closing the computer (Windows XP SP2), the Avast (visrus base updated) showed the alert VBS-malware-gen in logonui.exe and blocked the computer. Today, after the restart I checked logonui.exe with the Avast - same problem. Avast proposes me to cure it, I accept, then it proposes to change the file with a sane copy, I accept it, and the alert re-appears again and again.
I have no idea of where from the virus came. To check with an alternative mean, I launched CureIt! which ran also in Win32, and it didn't find anything suspicious. Could it be an Avast error or shoul I really worry?
Thank you for help!
