Hi, again! Unfortunately, I still cannot update virus definitions of Avast! 5.0.418 Free. This version 100220-0 I have mentioned in my last post was downloaded propably by myself, when I yesterday went to "Add or Remove Programs" in Control Panel and try to manually download latest virus definitions. Here are some logs from setup.txt, which might help you to rectify my update issue.

PS I have to remark, that my additional firewall Ashampoo 1.20, as well as Windows Defender are set to allow all Avast! 5.0.418 components to connect. Thanks in advance for your help.
