Where does this www.best-deals-products.com malware come from and how to remove it?

Recently I was approached by three to four Internet users who are having problem accessing some internet websites.

The common background/symptoms of their problems?

1) They all have JUST purchased Lenovo PC/Laptop, loaded with latest Windows 8.1 OS.

2) Of course, the device is preloaded with Lenovo stuffs, free AV, in their cases, is McAfee Internet Security, etc...

3) They have no problem browsing most of the websites but some websites would just be blank, or partially blank, or ... just look differently from others machine.

Here comes the troubleshooting steps:

Long story short, the following has been proven that they are not the culprit: Windows 8.1, Internet Explorer 11, Java 8 u25, McAfee Internet Security.

With the chance of able to run a basic HTTP traffic capture on one of the victim's machine, some secret trace of malware has surfaced...

What's this secret visiting to www.best-deals-products.com ???

Google the background of the malware (?), more details revealed:

One of the many faces of the real culprit is possibly one of the below:

They also own this software: SUPERFISH INC VISUAL DISCOVERY

According to records from who.is of Godday, which is the URL host, and also the past records in virus-total.com, this malware server is pointing to some servers in the shared server farm (could be virtual) based in US New Jersey.

Their address keeps moving, today, it's being resolved to IP 66.70.34.103 or 66.70.34.113.

In year 2012, someone from fergeek also found that one of the popular chrome extension, fast save, has this infamous malware too:

Tribalwar (which I suppose is web based game), is affected too.
