Avast vps file version should be 0432-1.

This could be something else in my opinion.
what version of service pack are you using? I suggest updating to sp4.

start internet explorer in the taskmgr (iexplore) and then browse to the windows download site. you can also “browse” to your local folder (c:\ for example…)

(you can get an alternative to explorer if you launch taskmanager (ctrl-alt-del-> taskmanager) and in the file->run box you enter progman (it’s the old windows gui)
