You can remove it from the template that shows the views.
/templates/default/postlist.tmpl would be the template to edit is my educated guess.
<td align="center" nowrap="nowrap" class="{$postrow[topic].color}topicviews" valign="middle">
{$postrow[topic].Views}
</td>
and
<td nowrap="nowrap" width="5%" class="tdheader" align="center">
{$lang.THREAD_VIEWS}
</td>
should be removed from that file I think. I did not test it, nor did I have a full look on other pages that might need some removal of views.
