Anti-virus:

Real-time protection

SpIDer Guard® resident monitor intercepts all calls to files located on floppy disks hard drives CDs Flash-cards and smart-cards preventing malicious code from getting to user computers. SpIDer Guard driver is highly resistible to external attempts to block its operation for example by a specifically designed malicious program.

Anti-Spam:

Anti-spam advantages

Client-independent solution

Dr.Web anti-spam is not a mail client plugin instead it is integrated into SpIDer Mail monitor and? therefore is compatible with any mail client. Using the anti-spam doesn’t significantly increase system load or slow down receiving mail.

POP3/IMAP4 filtering

The anti-spam supports both POP3 and IMAP4 incoming mail protocols. The latter allows instant access to messages stored on a server and choosing to download a message header body or attached files. So a user doesn’t download spam messages and therefore saves on traffic.

Anti-spam training is not required!

Unlike anti-spam solutions based on Bayesian filtering Dr.Web anti-spam doesn’t require training before one starts using it. The anti-spam begins working as soon as the first message arrives. If a false detection has occurred a message should be sent at a specified mail address for analysis and correction of the anti-spam analysis routines. Send notifications on false detection at vrnonspam@drweb.com for spam messages that managed to evade the filter use vrspam@drweb.com.

Intelligent processing of detected messages

Different filtering techniques are used for different types of undesired e-mail (phishing pharming scamming and bounce) to ensure high detection probability. Language-independent analysis allows detecting undesired messages regardless of their language. A big number of criteria is considered to decide between spam and not spam.

Easy to configure and to use

Even an inexperienced user can configure the anti-spam. If the anti-spam has been enabled it will start working as soon as the first message is received. Experienced users may be willing to take advantage of advanced configuration. One can set for example all messages with Eastern Asia encoding to be detected as spam. A user can create his own white and black lists – specify trusted and banned e-mail addresses.

Regular updates

In order to run an efficient business spammers have to alter their techniques every day to evade anti-spam solutions consequently developers of such solutions change their detection methods. An anti-spam requires updating as well as an anti-virus. Dr.Web anti-spam is automatically updated every day using updating utility. The unique Vade Retro technology based on several thousands of rules for detection of unwanted e-mail allows the solution to stay up to date with spammers with only one small-sized update in twenty-four hours. Spam analysis module doesn’t require a connection to a server or access to a database which also saves your traffic.

Filtered out messages are not deleted!

Messages that have been filtered out are not deleted instead they are placed in a specific folder. Create “Spam” folder in your mail client and add a rule for all suspicious messages to be automatically placed in the folder. You may check if all detected messages are spam at any time.

Stand alone anti-spam saves traffic

Filtering technologies

The filter sifts all incoming messages. It takes into account numerous criteria. Each examined message gets a number of points ranging from -5000 (negative not spam) up to 5000 (positive spam) with 100 increment. Depending on a number of points a message has received it can be delivered to a mailbox as a normal message or can be marked as spam.

Spam-filtering technique includes several thousands of rules that can be divided into groups.

Heuristic analysis

An extremely complex and highly intelligent technology of empiric analysis is used to check all elements of a message. An attachment if available is analyzed as well. New rules are contantly added to improve the heuristic analyzer.

Evasion filtering

Evasion filtering is one of the latest and most efficient technologies of Dr.Web anti-spam. It allows detecting techniques used by spammers to evade spam-filters.

HTML signature analysis

HTML tags included in a message are compared with samples of HTML signatures library of the anti-spam. Combined with data on size of images typically used by spammers it helps protecting users from spam-messages containing HTML tags and online images.

Semantic analysis

Words and expressions of a message are compared with spam cliches placed in a dictionary. Hidden words expressions and symbols are analyzed along with the text visible to a user.

Anti-scamming

Probably scamming (and pharming – a type of scamming) is the most dangerous type of spam; Typically a message is so called Nigerian scam a lottery or a casino money prize notification or a forged letter from a bank or loan office. A special module is used to filter out such messages.

Technical spam

A bounce message is a non-delivery notification message that can be received as a result of network worm ro spammer activity and is as undesired as spam. A special anti-spam module detects such messages and sets them as undesired.
