Avira antivir not updating automatically
He may have introduced problems because of his unfamiliarity with English.(I speak English but instructions for this type of software download sometimes confuse me).Occasionally I did let the programme run by itself to ensure no conflicts within my computer - which can also cause a failure.I would suggest that your friend uninstalls Avira and reinstalls it to see if that cures the problem.
I have mine set for 9 PM Central time (GMT -6), which is about 3 AM in Germany, and have not had a problem with crowded servers. OK, so I recently encountered some problems with Avira Anti Vir: the VDs just wouldn't update! However, I specifically reinstalled my entire security apparata afterward to make sure it recognized the new setup. It isn't the firewall; there are no block alerts, no popups asking me to block or allow the AV to download. It can only be updated manually by downloading its definition files. If that doesn't help I would look into two things, an infection or a problem with your firewall. Afraid of a glitch or something, I uninstalled Antivir and tried Comodo's IS suite. Now, I recently did change my DNS server IPs, coz the old IPs were pinging false. I try also installing some anti-spyware but still cannot update thru internet automatically.Actually they will ask you to do a manual uninstall in safe mode, linking to this knowledge base article:id=135I didn't go into safe mode, just did a normal uninstall, ran the registrycleanup from their page and then reinstalled.
