CNET Spybot Search and Destroy Download?

Hello,

 

After some spurious activity, someone downloaded Malwarebytes and Spybot Search and Destroy to double check Norton's (NIS 2013) results (that being - nothing).

 

Malwarebytes was downloaded from their own site, and only run on the free mode, not the trial of Pro.

 

Spybot however was downloaded from CNET. (Specifically: http://download.cnet.com/Spybot-Search-Destroy/3000-8022_4-10122137.html  / http://download.cnet.com/Spybot-Search-Destroy/3001-8022_4-10122137.html?spi=712ea8a46ff17b52bfb7b5963fe110d6 ).

 

My concern is that, given CNET isn't the 'official' download source for Spybot, is that download actually safe?

 

Thank you for your assistance
