I bought 2yrs for 5 computers Avast internet security 5.0. So far 3 have loaded up fine. But one of them the firewall won’t turn on. ??? Help
We do need a little information, don’t you think?
Operating system? 32 or 64 bit?
Any other AV- / Antispyware- or Firewall software running?
What was the AV that ran prior to Avast 5 on the PC? (Avast 4.8, Avira, AVG, McAffee…)
Was it an Update from Avast 4.8 or a fresh install?
