- Names, Categories, Sizes, Dates
- ===============================
-
- The records provide succinct profiles for each virus with the
- information being expanded, as it becomes available to include:
-
- 1. NAME
-
- This field shows the name(s) which have been given to the virus (or
- other dubious program). The first name is either its 'preferred
- name' or 'family name' followed by any other names that are still in
- common use. Confusing descriptors like II, IIb, or -2 have been
- eliminated as far as possible because the fuller descriptions now
- available to users of PC-Virus Index make many of them redundant.
- Superseded aliases that have had only limited acceptance have also
- been excluded.
-
- 2. SIZE
-
- The virus sizes that have been reported are listed. Several viruses
- have the same size, in some cases as a matter of accident and in
- other cases by deliberate design.
-
- 3. COUNTRY, DATE, STRAINS
-
- Where a country of origin of a virus has been attributed, it is
- noted together with the date first reported and the number of
- strains. The strains might come from anywhere, so these three
- fields are not necessarily associated. In several cases, the number
- of strains shown almost certainly understates the actual number in
- existence.
-
- 4. EFFECTS
-
- A brief overview is provided on each virus as soon as possible but
- sometimes it takes weeks for information to filter through on what
- any particular virus does. Not all the effects are known but most
- viruses can cause damage of some sort, many quite deliberately.
-
- 5. CATEGORY & SORT ORDER
-
- All the records have been categorized and (by default) are sorted by
- name within category. The categories are:
-
- Dual: Boot Sector & File Virus
- Boot Sector Virus
- File Virus
- Trojan
- Joke, etc
-
- The first three categories describe the areas targeted by the
- viruses. Some trojans and jokes are also listed, where these have
- been either been mistaken for viruses or are in some way associated
- with them.
-
- A TROJAN is a program that pretends to do something useful while
- actually causing damage and it generally relies on the preparedness
- of a user to try an 'unknown' program. Unlike a virus, a trojan is
- not able to reproduce itself but there are now trojans that drop
- viruses and viruses that drop trojans.
-
- JOKES: Some 'viruses' simply turn out to be jokes and whether a
- malicious program is a joke or a trojan is largely a matter of
- whether or not you are on the receiving end.
-
-
- SORTING THE RECORDS
-
- The records can be resorted to the order of your choice by use of
- the RE-INDEX option, provided on the Opening Screen. When
- delivered, PC-Virus Index has been sorted by Name within Category
- and will build an index for itself accordingly.
