Best antivirus for remote work
The confusion
Remote work security advice splits between 'your employer handles it' and 'you're responsible for your own machine.' In practice, many remote workers are somewhere in between — using a personal machine for work tasks, or a work machine for personal browsing, without clear guidance on what protection is expected.
A machine used for remote work connects to company systems, stores credentials for internal tools, handles client documents, and sits on a home network that may include family members' devices. That's a different threat exposure than either a pure personal machine or a fully managed corporate endpoint — and most antivirus recommendations don't address it.
What makes remote work a distinct configuration isn't the job title — it's the combination of high-value access (company systems, client data, production credentials) with lower-oversight infrastructure (home network, personal device, no corporate IT to catch what you miss).
What most people assume
Most people assume their employer's VPN or security tooling covers the device when connected to company systems. Corporate VPN encrypts traffic between the device and company infrastructure. It doesn't scan the device for malware, monitor what's running locally, or protect anything that happens when the VPN is disconnected — which is most of the time for most remote workers.
Most people assume the separation between work and personal use on a shared device is sufficient protection. A browser profile for work and a browser profile for personal use don't create separate security boundaries. Malware installed during personal browsing has access to the entire machine — including credentials cached by work applications, documents in shared project folders, and any saved authentication tokens for company systems.
Most people assume the protection appropriate for a personal machine is sufficient for a machine that also handles work. The consequence calculus is different. A compromise of a personal machine affects personal data. A compromise of a remote work machine may also affect client data, access to employer systems, and professional liability. The protection investment should reflect which scenario is realistic.
What's actually true
For a remote worker on a personal machine without employer-managed security tooling: Bitdefender covers the widest range of threats with the least configuration overhead, and includes ransomware rollback — relevant when work documents and client files are stored locally. ESET is the alternative for machines where performance matters — developer workstations, machines with intensive local processing.
The attack vectors most relevant for remote workers are phishing targeting work credentials (not meaningfully different from home user phishing, but with higher-value targets), malware delivered through work-adjacent channels (fake invoice attachments, collaboration tool phishing), and credential theft through browser-stored passwords for company systems. A product with strong behavioral detection and phishing URL protection addresses these specifically.
Where you might be
If you're on a personal machine with no employer-managed endpoint protection — no MDM, no corporate EDR, nothing installed by IT — the machine's security posture is entirely your responsibility, and the threat model includes both personal and professional exposure.

If the machine is used for development work or runs resource-intensive local processes during work hours — ESET's low overhead profile keeps the machine protected without competing for the same CPU budget as the work tools.

If the machine is employer-managed with corporate security tooling already installed — adding a second real-time antivirus causes conflicts. The question is whether the employer-provided tooling is active and current, not what to add on top of it.

Antivirus doesn't protect company systems from a compromised endpoint — it protects the endpoint. If credentials stored on the device are stolen before malware is detected, access to company systems through those credentials is already compromised. Credential management — not reusing passwords, using a password manager, enabling MFA on work accounts — is a separate and more direct defense for the access question.
A home network that includes other devices — family members' machines, smart home devices, unmanaged hardware — is a shared attack surface. Malware that reaches any device on the network may be able to reach a remote work machine through local network access. Network-level protection (router-based DNS filtering, network segmentation) is outside what endpoint antivirus addresses.
Employer security policies may specify or prohibit specific security products on devices that access company systems. Installing a third-party antivirus on a machine that's subject to employer IT policy without checking that policy first is worth avoiding — some corporate security tools conflict with consumer antivirus, and some policies prohibit personal security software on work-connected devices.
