Does Virus total Detect 100% Malicious Code?

Hi, I Want To Know, Does Virustotal Scan 100% Malicious Codes. I Downloaded A Plugins From free Sites, and I scanned In Virustotal.com now It shows 100% Clean(No threat Detect) can I use That Plugins In My Sites.

Is it Safe To Use Scripts which shows 100% Clean(no Threat) In Virustotal.com?

!!Suggestion Please!!

Virustotal uses multiple (around 67 if i'm right) antiviruses to scan files,
none of these antiviruses is 100% accurate, but using them all together, you can make sure it's 99% safe,
correct me if i'm wrong,

If you want to make sure you're safe, you can always take a look at @Festinger vault,
Download all what you need for a small monthly fee

It won detect all, try buy from a reliable source @Festinger
