Do you, or did you have another anti virus program installed? If so what was is and how was it ununstalled?

What is your operating system and other security programs running?

Can you rephrase? I can’t understand…

Which file? Where is it (path)?

Can you write the full error message? Is it an avast error message or a Windows one?

What they cannot use? avast? that file?

Can’t you boot?
Which option are you talking about?

We will need more information to be able to help you:

  • Which OS are you using? Is it up to date?
  • What avast! version and VPS file (virus database) number?
  • What was the filename and path where the virus was found?
  • Which actions have you taken to try solving the problem?
  • Do you use a firewall? Which one?
  • Do you have any other antivirus installed in your system?
  • Any other security programs that could interfere?
  • Any useful information into Control Panel > Administrative Tools > Events, specially ‘Errors’.
