Using our online scanner you can see whether your current machine has let any infections in.

Protection from the unknown
Our Award-winning ThreatSense® technology uses various techniques, including heuristics (a form of artificial intelligence). This helps us detect un-cataloged threats providing you with the most effective protection possible. Combined with our firewall it ensures your safety not only from new viruses but also unwanted hackers and intruders.
Finds malware others have let in
Detecting viruses in real time, using heuristic analysis of program's ThreatSense scanning engine makes our software superior.
Keeps your machine running faster
Traditional antivirus software is well known for making computers run considerably slower than normal. ESET NOD32 Antivirus has been designed to be lightning fast, so fast you won't even notice it's there. Even intensive operations like performing a "full disk scan" happens in the background without affecting your computer's speed.
UK-based phone support
If you have any problems as a new or existing ESET customer, you have free access to our UK-based technical support team 7 days a week. Visit our support section.
Improves computer performance
ESET NOD32 Antivirus is fast and light typically using just 44 MB of memory - a fraction of other products. Switching your antivirus to ESET NOD32 Antivirus can be like buying a new computer. Plus laptop, notebook and netbook users will also benefit from extended battery life thanks to our new automatic energy-sipping battery mode.
Free protection for additional OS
Our Unilicencing model allows you to use one licence to protect a range of platforms on one machine without the need to buy further licences.
Smarter Scanner
Threats don't always enter in ways you expect. ESET NOD32 Antivirus inspects SSL-encrypted communication channels like HTTPS and POP3S, and intelligently scans compressed files to find threats that other products miss. ESET's Smart Optimisation feature makes file scanning faster than ever.
System Tools
ESET SysInspector and ESET SysRescue simplify diagnosing and cleaning of infected systems by allowing deep scans of system processes to find hidden threats, and creating bootable rescue CD/DVD or USB drives to help you repair an infected computer.
Trusted Zone Authentication
Identify trusted network zones by network configurations (a configurable combination of host/DNS/DHCP server IP address, wireless SSID, connection profile, etc) or securely authenticate into a network using ESET Authentication Server.
Removable Media Security
Threats can enter your PC from removable media such as USB thumb drives. For self-running media, ESET NOD32 Antivirus scans autorun.inf and associated files when the medium is inserted, in addition to scanning any file on any removable device when it is accessed, or during a full-scan of the media.
Self Defense
ESET NOD32 Antivirus for Linux has built-in technology to prevent malicious software from corrupting or disabling it, so you can rest assured your system is always protected.
