Eighty percent of users’ browsing histories can be captured by online trackers, InfoSecurity Magazine reports. Summarizing Norton Labs’ quarterly Consumer Cyber Safety Pulse Report, it showed consumers are monitored by an average of 177 different organizations per week. The report also found half the trackers can obtain the 80% of browsing history within the first two hours of surfing the internet. Even if users deleted their history every day, they would re-encounter half the trackers within two hours. Also, Norton reported blocking approximately 3.6 billion cyberthreats last year.
