If you mean with "agreeing not to download" the field you have to mark before being able to download the LW.exe, then the answer is "No".
Only if you decide (after installation) not to get search results of files without license, it will have an effect on the search results.
The problem with viruses included in exe/rar/zip files is not connected to what LW version you're using. This problem occures due to people downloading/uploading/sharing such files.
Except not to donwload such files, there is not much you could do about.
