With the rise in the number of online scams, tech giant Google has warned and alerted Gmail users about five key scams and spams during the holiday season. 

The company advised users to avoid gift card and giveaway frauds, charity-related scams, demographic targeting scams, subscription renewals frauds and crypto scams.

The tech giant protects users from around 15 billion unwanted messages a day and blocks more than 99.9 per cent of spam, phishing and malware, the company said in a blogpost.
