Overview

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Aliases

• Quicksilver.1376

• Quicky

Characteristics

Quicky.1376 is a memory resident, file infecting virus. It infects .EXE files.

Upon infection, this virus become memory resident as a low system memory Terminate-and-Stay Resident (TSR) of 1,664 bytes. Interrupts 13 and 21 are hooked by the virus in memory.

Once the Quicky.1376 virus is memory resident, it infects .EXE files as they are executed. Although, it does not infect files located on the A: drive.

Additional Comments:
The Quicky or Quicksilver virus was received in July, 1995. Its origin or point of isolation is unknown. Quicky is a memory resident infector of .EXE files. It does not infect files located on the A: drive. When the first Quicky infected program is executed, this virus will become memory resident as a low system memory TSR of 1,664 bytes. Interrupts 13 and 21 will be hooked by the virus in memory. Once the Quicky virus is memory resident, it will infect .EXE files on the system hard disk when they are executed. Infected files will have a file length increase of 1,376 bytes with the virus being located at the end of the file. The program's date and time in the DOS disk directory listing will not be altered. The following text strings are encrypted within the viral code: "CHKLIST.TAV" "QUICKY" This virus may interfer with the functionality of some versions of Turbo Anti-Virus.

Symptoms

The following text strings are encrypted within the viral code:

"CHKLIST.TAV"
"QUICKY"

Infected files have a file length increase of 1,376 bytes. The virus is located at the end of the file. The file's date and time in the DOS disk directory listing is not altered.

Method of Infection

The only way to infect a computer with a file infecting virus is to execute an infected file on the computer. The infected file may come from a multitude of sources including: floppy diskettes, downloads through an online service, network, etc. Once the infected file is executed, the virus may activate.

Removal

All Users :
Script,Batch,Macro and non memory-resident:
Use current engine and DAT files for detection and removal.

PE,Trojan,Internet Worm and memory resident :
Use specified engine and DAT files for detection. To remove, boot to MS-DOS mode or use a boot diskette and use the command line scanner:

Additional Windows ME/XP removal considerations

Users should not trust file icons, particularly when receiving files from others via P2P clients, IRC, email or other mediums where users can share files.

AVERT Recommended Updates :

* Office2000 Updates

* Malformed Word Document Could Enable Macro to Run Automatically (Information/Patch )

* scriptlet.typelib/Eyedog vulnerability patch

* Outlook as an email attachment security update

* Exchange 5.5 post SP3 Information Store Patch 5.5.2652.42 - this patch corrects detection issues with GroupShield

Additionally, Network Administrators can configure this update using an available tool - visit this link for more information .

It is very common for macro viruses to disable options within Office applications for example in Word, the macro protection warning commonly is disabled. After cleaning macro viruses, ensure that your previously set options are again enabled.
