Hello, Today after the boot of my pc, nod32 v4 informs me that "Maximum protection is not ensured". Also there is the following message "Analysis of application protocols will not function - An error occured while starting service. Analysis of application protocols (POP3, HTTP) will not function". But the Antivirus function is checked as green. Also, nod32 seems to be enabled despite the fact that the ESET SYMBOL is red. For instance I did not found the solution to gho back to the normal situation. Here are two pics : http://img9.imageshack.us/img9/8558/nod321a.jpg http://img9.imageshack.us/img9/954/nod322g.jpg Thank you for your advice to resolve this problem.
