OK, so I recently encountered some problems with Avira AntiVir: the VDs just wouldn't update! I had to manually DL the database and install it. But of course, the problem persisted. Afraid of a glitch or something, I uninstalled Antivir and tried Comodo's IS suite.
Same result. The virus database wouldn't update. Every time I tried, I got 'Update failed. Unable to connect to the Internet'.

Today, I DLed and installed PC Tools' Antivirus, but it told me the same damn thing again: 'The virus database could not be downloaded. Please check your internet connection and try again.' This on a 24/7 broadband connection with 2 mb/s speed.
Software Informer was another software that freaked out on me like this. It was more specific, however: 'Error 106. Please check your internet connection and try again'.
Now, I recently did change my DNS server IPs, coz the old IPs were pinging false. However, I specifically reinstalled my entire security apparata afterward to make sure it recognized the new setup. Yet the problem persists. It isn't the firewall; there are no block alerts, no popups asking me to block or allow the AV to download.
Oh, and PS. My specs are on my sig.
Waiting for a solution, guys!
