| eScan primarily uses MWL to scan the incoming and outgoing network traffic. MWL is placed above the Winsock layer of the operating system. (See Figure 1. MWL Filters) All data passing through the Winsock layer has to pass through MWL. Thus, MWL acts as a transparent gatekeeper and monitors data packets for malicious content. It assembles the data packets coming from different TCP/IP ports into files based on their type into e mails, e mail attachments, or Web traffic, such as FTP traffic or ICQ traffic. It then passes the files through numerous filters, such as virus filters, content filters, and attachment filters. These filters check and issue dynamic notifications based on the validity of the content within each file. | eScan primarily uses MWL to scan the incoming and outgoing network traffic.

| - | '''MicroWorld’s revolutionary concept to tackle the Content Security threats''' | + | |
| - | + | ||
| - | The overall business scenario is undergoing a rapid change with Information Technology providing more advanced and rapid means of business communication like Internet and e-mails. However, as far as information that is being made available across the computer systems is concerned, there is a race to restrict its access, guard against information abuse and protect the valuable content. | + | |
| - | + | ||
| - | Virus-pranksters are now using the Internet as a frictionless distribution channel for dangerous viruses and worms. Over the years, contemporary virus threats have transformed into content security threats. These comprise e-mail and web-based virus downloads, MS Word based macro bombs, offensive e-mail and web content, misuse / abuse of e-mail resources, junk mail and Spam infections, harmful Java or ActiveX applets, intrusion of anonymous Internet users and trespassing of unauthorized bodies into the company's internal network. | + | |

| - | These threats not only damage files and computers by acting as viral agents, but also impose productivity losses, wasting disk space, time and financial resources. Ironically, even as certain methods to guard Content Security have evolved, threats to security have become more severe, even causing destruction of data. However, the systems employed to detect these threats are still handicapped by several deficiencies. The "cure" that is provided by other products only scans data after it is saved on the hard disk; by which time the damage is already done. | + | |
| - | + | ||
| - | + | ||
| - | The "MicroWorld-WinSock Layer" (MWL) is a revolutionary concept in scanning Internet traffic on a real-time basis. This new concept has changed the manner in which Content Security threats are tackled in the knowledge world. MWL is revolutionary because unlike the other products and technologies, currently available, MWL tackles a threat before it reaches your applications. Other products deal with the threat after the applications have already processed it. | + | |
| - | + | ||
| - | + | ||
| - | Technically, MWL is placed above the WinSock layer and acts as a "Transparent Gatekeeper" on the WinSock layer of the operating system. All data packets coming on different TCP/IP ports are assembled. It then decodes e-mail and web traffic, FTP and ICQ traffic along with all the attachments and passes them through numerous filters such as Virus Filters, Content Filters, Attachment Filters, etc. These filters check validity of the file's content and issue dynamic notifications. | + | |
| - | + | ||
| - | + | ||
| - | MWL technology oversees all data flowing to-and-from the Internet, thereby allowing it to process it without interfering with the applications. Dynamic compression and decompression facilities of data flow, between the Internet and your computer in order to maximize effective bandwidth usage are thus provided by MWL. | + | |
