In this age of connectivity, utmost importance should be given to the security of the system. Otherwise there is a chance of the system being hacked. Avast is a robust antivirus program. However, even a premium antivirus program like Avast can be corrupt or act inconsistently or even stop working completely. Then the problem needs to be fixed as soon as possible to restore adequate security to the system. Even if the antivirus program has not stopped completely but is in a conflicting state, action must be taken as soon as possible. Delay to take the appropriate action on time may lead to loss of data and other dire consequences.
