Free Antivirus Built with Award-Winning Technologies
With AI-driven threats evolving at a breakneck pace, you need a free antivirus that adapts at lightspeed
The digital Stone Age of easy-to-spot viruses is over. Today’s e-threats - from Zeus P2P to Clop Ransomware - go straight for your wallet and are smarter than ever at evading detection, scaling across networks, and changing in response to thwarted attacks.
Bitdefender Antivirus Free for Windows keeps you safe, even against today’s constantly changing e-threats
By learning & monitoring the unique pattern of daily activity on your PC, Bitdefender Antivirus Free is able to instantly detect and isolate suspicious changes in real-time, no matter the source.
So you’re shielded from known and emerging threats, including …
Ransomware
Financial extortion attacks that freeze PCs are on the rise, attacking everyone from individuals to global enterprises
Cryptojacking
With cryptocurrency soaring in popularity, hijacking PC resources to mine for coins has become an all-too-common hazard.
AI-powered “spearphishing”
AIs like GPT-3 are now being exploited to write shockingly personalized emails that can dupe just about anyone.
"Zero-day exploits”
Every software update comes with flaws that need fixing. Until they’re detected, hackers use them as infection points.
Rootkits & Trojans
Notoriously hard to detect, these attack your PC’s central nervous system and use its credentials to steal & impersonate you.
Malicious websites & files
Malware can be embedded into almost anything you click on, including “next-gen” financial assets like NFTs.
