Disinfection & Removal

Automatic Disinfection

Allow F-Secure Anti-Virus to disinfect the relevant files.

For more general information on disinfection, please see Removal Instructions.



Technical Details

Such viruses are grouped in the following families:

SillyC   - Non-resident viruses, which infect only COM files
SillyE   - Non-resident viruses, which infect only EXE files
SillyCE  - Non-resident viruses, which infect both types of files
SillyCR  - Resident viruses, which infect only COM files
SillyER  - Resident viruses, which infect only EXE files
SillyCER - Resident viruses, which infect both types of files
SillyOR  - Resident viruses, which overwrite the host files

The variants in each family are named by their infective length.

it might be a good idea to search all files for infection, as some members of SillyOR family will corrupt data files by overwriting them with their own code. F-Secure anti-virus products are able to locate these corrupted data files so you can replace them with good copies.


Variant:SillyC.373

Size:373

Other:Resident, COM-files

This virus infects COM files and EXE files with COM extension. It doesn't check the host file size before infection so it can corrupt large COM files. It marks infected files by adding 100 years to the file date and setting the second fields to 62.

The virus has no texts or activation routine.

This virus was reported to be in the wild in Hungary in January 1996.
