NortonLifeLock offerings may not cover or protect against every type of crime, fraud, or threat we write about. The feature was introduced in June , allowing Norton subscribers to mine for Ether, the cryptocurrency of the Ethereum network. At the time, the move was criticized as an opportunistic attempt to capitalize on the crypto boom, irrespective of the environmental impact or the financial risk to users.
Now, Norton customers have taken to Twitter to complain that the crypto miner is far more difficult to uninstall than it should be. Others suggest it should not be installed on machines in the first place without the explicit consent of the user. Others, meanwhile, took issue with the condescending tone of the response from customer service, and suggested Norton should stick to its lane as a cybersecurity company. These hackers may be able to see what websites you visit, messages you send, videos you watch, and files you download.
They might be able to steal your log-in and password information, giving them access to your online credit card and bank accounts. Avoiding this trap is simple: Never use public Wi-Fi to access sensitive financial accounts. If you want to transfer money or pay your credit card bill online, use a secure internet connection. To boost your security, consider using a VPN — short for virtual private network — which can encrypt the information you send and receive online while browsing the web.
One way to do this is to log onto your online bank accounts and credit card portals every day. Look for suspicious purchases or withdrawals. Pay for it with your credit card, not a debit card. If someone steals your credit card information, you can easily dispute the illegal charges and have them removed from your bill.
But it someone steals your debit card information and drains the bank account connected to it? That money is gone, even if you call your bank and dispute the purchase.
Just consider the problems you might face if you lose your smartphone. If a thief finds it, that person might be able to use your phone to read your email messages, steal your bank account information, or log onto any other sites you regularly visit.
This could lead to the scammer using your credit card to make online purchases, using your account information to buy items from your favorite gaming sites or taking over your email account to send spam messages to your friends.
The lesson? Always keep track of your devices. And make sure to password-protect your smartphone and laptop so that if you do lose them, it will be more difficult for others to log onto them. That brings us to passwords. You already know that strong passwords are important to keep snoops from hacking into your online bank accounts, credit card portals and email accounts.
Use passwords that are difficult for others to guess, ones that include a combination of numbers, uppercase and lowercase letters and symbols. Or use a passphase, a string of words that you can remember, but others would find hard to guess. These are fake emails that can look surprisingly legitimate. If you get tricked into clicking a link or providing information, thieves can get your passwords and account numbers.
Buying subscription-based antivirus software that specifically targets phishing is one way to help protect against being scammed.

But the most important way to protect against phishing is to be informed.

In addition, with the evolving threats facing consumers as well as the proliferation of free public Wi-Fi, the timing is right to provide consumers with a strong trusted VPN-focused product like Norton Secure VPN. Connecting your device to a password-protected Wi-Fi access point does not protect your data as it is broadcast from your device to the hotspot.
Passwords on Wi-Fi access points only ensure authorized users are connecting to the hotspot. So, your data may be at risk as it traverses the airwaves between your device and the hotspot. Also, if you are using public Wi-Fi where all users have access to the same password, it may not be secure from hackers and snoops. Free is not always free.
Often, free VPN products trade your information to help offset their costs. Norton Secure VPN does not impose data or bandwidth limits or advertisements on you. An unlimited data and bandwidth VPN service has significant ongoing costs. Those costs are necessary to ensure your privacy.
