Real-time protection (SpIDer Guard file monitor)
Real-time monitoring of the system’s health — interception of all calls to files located on local drives, floppy discs, CD/DVD/ Blue-ray disks, flash-drives, or smart cards.
File monitor is highly resistant to attempts by malicious programs to disrupt its operation.

Anti-rootkit technology (Dr.Web Shield)
Reliable system protection from viruses featuring rootkit-technologies that allow viruses to hide their presence in a compromised system.
Neutralization of complex rootkits (Shadow.based (Confiсker), MaosBoot, Rustock.C, Sector).

Virus-free e-mail (SpIDer Mail)
On-the-fly virus scanning of e-mails over SMTP/POP3/NNTP/IMAP4 that doesn’t affect performance of mail clients and doesn’t cause receipt delays
Individual processing rules for different types of malicious objects — viruses, riskware, adware, hack tools, paid dialers, and jokers
An analysis of message contents and sending time allows the characteristics of malicious activities to be detected and prevents mail worms from carrying out mass mailings

Spam-free e-mail (Dr.Web Anti-spam)
Real-time filtering of incoming and outgoing e-mail.
The anti-spam doesn’t depend on a mail client and doesn’t cause receipt delays.
The anti-spam doesn’t require configuration and starts working as soon as the first message is received.
Different filtering technologies ensure the high probability of detecting spam, phishing, pharming, scamming and bounce-messages.
Anti-botnet – you won’t be disconnected from the Internet because your computer sends out spam.
Messages that have been filtered out are never deleted. Instead they are placed in a separate folder where you can always verify that no false detection has occurred.
The standalone anti-spam analyzer module doesn’t require connection to an external server or access to a database, saving on traffic.

Shield from Internet threats (SpIDer Gate HTTP monitor)
The SpIDer Gate module scans incoming and outgoing HTTP traffic in real time, intercepts all HTTP connections, performs data filtering, blocks infected web-pages in any browser, scans files in archives and protects users from phishing sites and other dangerous web-resources.
SpIDer Gate operates independently from web browsers.
Filtering doesn’t affect the overall system performance, surfing speed or traffic.
No configuration is required in the default mode; Dr.Web SpIDer Gate starts scanning right after installation.

Web-surfing control (Dr.Web Parental control)
Protection of children from exposure to objectionable content.
Block of access to web-sites from the list divided into 10 subject groups (Adult content, violence, weapons, drugs, gambling, etc.).
Block of access to removable data storage devices, files, folders or network drives – an additional measure to protect data from deletion or unauthorized access.

Protection from network attacks (Dr.Web Firewall)
Protects against unauthorized access by a network; prevents data leaks; blocks suspicious connections on package and application layers.
The application layer connection control manages the ability of applications and processes to access network resources and registers access attempts in the applications log.
The packet layer filtering allows controlling connection to the Internet regardless of an application that uses it. The packet filter log stores information about packets sent over network interfaces.
