Choosing internet security
Internet Security suites build on core antivirus with tools aimed specifically at online activity: a managed firewall, phishing and malicious-site filtering, and often protections for online banking or webcams. They sit between a basic antivirus plan and a full Total Security bundle.
- If you frequently shop or bank online, the added phishing/site-reputation filtering in this tier is usually worth the step up from basic antivirus.
- Check whether the firewall tools are described as 'managed' (mostly automatic) or require manual rule configuration — this affects how hands-on the product is day to day.
- Confirm device count and platform coverage per license before purchasing for a family or shared household.
Frequently asked questions
What's the real difference between Internet Security and plain Antivirus?
Internet Security adds network- and browser-facing protections — typically a two-way firewall and malicious/phishing site filtering — on top of the malware scanning engine found in the brand's antivirus tier. The exact feature list varies by manufacturer, so check the feature list on the publisher's product page.
