Now when I finally made Avast! scanner running the next problem occured:
When I try to run Outlook Express, there comes two messages on the screen:
In first message OE says that it couldn't create some kind of Internet - account control. It says that the memory has ran out or hard disk is full, but it can't be possible. (Message ID is 0x800CCD01)
After I click "OK" button, the next message occurs and it says that it couldn't format file "Msoe.dll" and OE could have been installed inproperly.
After I click "OK" button, nothing happens... Before installing Avast! OE ran Ok.
Platform was Pentium 75mHz, 64Mb RAM, Windows 95, IE 5.5 with desktop update.
