Antivirus guard SpIDer Guard for Windows 95/98

In February 1999 a new antivirus program SpIDer Guard guaranteeing reliable antiviral protection of your personal computer was released. SpIDer's program base is Doctor Web, it is a resident guard working under Windows 95/98, included in DrWeb for Win32. SpIDer's principal features and options are:

SpIDer is a resident program, i.e. it is a permanently operating in the computer memory antivirus program for Windows 95/98 environment;
SpIDer performs a "flying" file and disc system sector calling scanning;
SpIDer supports a special blocking mode preventing from loading into computer memory a wide variety of known and even unknown resident Windows-viruses that can not be detected by heuristic analyser.

SpIDer Guard uses the same kernel and antivirus database as all antivirus scanners of the DrWeb32 family, which empowers SpIDer with much of Doctor Web's functionality, including the ability:

to detect and remove all known viruses (boot, file, macro, HTML, etc.) from files and disks;
to scan packed executable files and archives;
to detect and disable viruses in computer memory.

Unlike Doctor Web, SpIDer Guard can operate automatically, i.e. without requiring the user to make any special effort to scan his system. SpIDer can monitor such operations as file creation, file write, and program launch. However, monitoring all these operations may slow down the system due to the time-consuming antivirus check. A reasonable compromise between antivirus protection and system performance might be the so-called Smart Mode which reduces the check time by several times, while preserving the protection reliability.

A particular case is that of automatic e-mail attachment antivirus checking (generally speaking, not depending on the mail program). If the attached file is infected, the virus will be detected as soon as the user tries to open it and the system will create temporary file for the extracted virus. If the infected file is delivered via Internet or some other channel of e-communication, it will be detected immediately when creating file on the user's computer.

The above mentioned viral activity control mode is to be specially mentioned. This means that SpIDer prevents infecting even if the infector can't be identified by Doctor Web's heuristic analyser. In other words, even if DrWeb fails to detect a well disguised unknown virus in a program body, the virus will be caught by SpIDer when it attempts to activate.

While other memory-resident monitors often respond to each "virus-like" action and irritate the user with their obtrusive suspiciousness, SpIDer undertakes a heuristic analysis of a whole set of potentially dangerous operations and avoids false alarms in most cases. At the same time, intensive testing has shown that SpIDer successfully detects more than 90% of viruses "in the wild".

The program also offers a few features that make it easy to use:

easy install/uninstall procedure;
intuitive interface for configuring the operational mode that can be accessed from the task tray;
detailed logging of all operations and cumulative check statistics;
automatic check of floppy disks (including auto-check before rebooting to prevent accidental infection by boot viruses);
low usage of system resources.

With the advent of SpIDer Guard, DialogueScience anti-virus products have become even friendlier to end users. We are trying to make our programs as easy to use as possible, preserving, at the same time, their quality and reliability. The recent step we've made in this direction is SpIDer Guard that streamlines and automates the protection of Windows systems against viral attacks.
