Full antivirus software available for free that combined a firewall, password manager, vulnerability scanner and intrusion detection.

Bitdefender Free is an excellent free alternative compared to other full packages available out there for users, but Bitdefender seems to go that extra mile by providing real-time protection and HTTP-based virus prevention. Many of the freeware versions of antivirus products lack these two features and Bitdefender Free doesn't let down.

This antivirus solution is able to effectively protect users against common viruses, worms, spyware, rootkits and online phishing scams. The real-time protection feature of this antivirus program is quite good and is able to immediately protect you against imminent threats.

Bitdefender Free is a step up from previous versions as it has improved its footprint on system resources. When we tested it, it used little RAM and CPU.

When you initially install it, this free antivirus product will be optimal for most users, meaning there is little messing around involved with settings. On that note, the freeware version doesn't include as many settings as higher-tier products.

If you're looking for a safe and effective freeware antivirus program, the newest version of Bitdefender Free exceeds expectations.
