Dr.Web for Windows 95/98/NT

Functionally, this program and the traditional DrWeb for DOS are very much alike. The program is designed for 32-bit Windows (i.e. Windows 95/98 and Windows NT 4.0 or higher) and is referred to as Dr.Web for Win32 or, briefly, DrWeb32W.

This version is released in two variants, graphical (DrWeb32W) and command line (DrWebWCL). Both programs support the same command line switches given below. However, DrWeb32W can be configured via dialogs, which, usually, is more convenient. On the other hand, DrWebWCL requires less system resources.

Both programs use the same configuration file and the same option group in it. You can alternatively use both variants, whichever is more convenient at a given time.

Dr.Web for Win32 can work with ADinf32 and ADinf for DOS, but would refuse to communicate with 16-bit ADinf for Windows.

SpIDer Guard for Windows 95/98

Now, there is one more program in Dr.Web for Win32 distribution kit. This is a memory-resident anti-virus program called SpIDer Guard for Win95/98, or briefly SpIDer. It based on the virtual driver (VxD) technology.

SpIDer intercepts all attempts to access files and disk system areas and checks them for viruses "on-the-fly". Having detected a virus, SpIDer removes or locks it, granting access to the infected file only if it has been successfully cured.

SpIDer can operate in a special mode when it's able to detect and block a virus-like activity (i.e. attempts to infect files and other objects on your hard disk) of any (even unknown) virus.

SpIDer uses the same virus database and program kernel as Dr.Web for Windows 95/98/NT does.

SpIDer is included in the Dr.Web for Win32 Distribution Kit and is installed with the same setup program.

When starting, SpIDer checks the computer memory. After that, SpIDer's icon appears on the Windows System tray. Right click this icon to appear SpIDer menu. And double left click this icon to open the Options dialog where you can reconfigure SpIDer.

If you shutdown Windows with a floppy disk inserted in drive (A:), SpIDer will check the diskette to prevent possible infection of your system after the next boot.

Dr.Web for DOS/386 (command line)

- no practical limitation on the conventional memory. The program can operate in the environment with less than 200K of main memory;

- support of the latest (memory-consuming) archive methods, employed by RAR 2.00, etc.;

- faster scan process. As compared with the 16-bit version, DrWeb32 may show increase in performance by 15-20% (if DrWeb16 was optimally configured) up to as much as 300% (if DrWeb16 had to run in a particularly unfriendly environment).

Using of DrWeb386 are recommended for virus checking under DOS, before Windows starts.

DrWeb386 is installed with the same setup program from DrWeb32 distribution kit.
