SpIDer Gate scans HTTP traffic and blocks malicious objects. HTTP is used by browsers, download managers, and other applications which work with the internet. SpIDer Gate can check data transmitted over cryptographic protocols, such as HTTPS. For that, enable the Scan encrypted traffic option in the Network section.
By default, SpIDer Gate filters non-recommended websites and websites known as infection sources. The information on such websites is also obtained from real-time data stored on Dr.Web cloud service.
SpIDer Gate automatically launches on Windows startup and resides in memory.
To enable or disable traffic scan and non-recommended websites filter
1.Open Dr.Web menu 
, then select Security Center.
2.In the open window, click Files and Network tile.
3.Enable or disable SpIDer Gate by using the switcher 
.

Level of system resource consumption. In some cases Dr.Web cannot determine the final file size for example when loading the file. In this case, the file is sent for the scan in parts. It requires the use of computer resources. You can configure the resource use level and determine the frequency of sending files with unknown size. If you select a high resource use level, files will be sent more frequently and will be scanned faster. However, frequent scans increase processor load.
Traffic scan mode. By default, SpIDer Gate scans incoming traffic only. If necessary, you can select HTTP traffic type to scan.
During the traffic scanning, the SpIDer Gate parameters, the white list, and the list of applications excluded from scan have an effect.
