ViewPassword.com is a website that adds itself to the user's browser an then infects the user's browser with adware. It infects the computer by redirecting to ad websites, and will then say "by ViewPassword.com."
It is not dangerous, but it is annoying. It will make hyperlinks, and can add PUPs to the user's computer. It can be removed, but it is difficult. It can also make ads pop up more often. The user usually gets this adware from downloading trojan freeware, and other type of freeware from download websites like Softonic.com.
