- What's New In VIRx Version 2.3
- ==============================
- Date: 05/22/92
-
- 1. This release of VIRx detects 73 new viruses, bringing the total
- to 925 total strings.
-
- 2. VIRx now detects all files encrypted with the "Mutating Engine"
- attributed to the Dark Avenger that are not already destroyed by the
- Engine's attempts to encrypt them (and most of those, as well).
- If you find executable programs with MtE encryption that we miss,
- please advise us at Microcom. As always, the BBS number is:
- (919) 419-1602 v.32bis.
- We can be reached through the Internet at trent@rock.concert.net,
- and through FIDONet NetMail at "Glenn Jordan@1:3641/1.201".
-
- 3. Due to an intensive reworking of the code, we have sped up the
- scanner's raw speed by yet another 20%.
-
- 4. VIRx v2.3 will start to warn users it is getting dated in July.

- VIRx 2.2 Revisions
- ==============================
-
- Date: 04/14/92
-
- 1. This release of VIRx detects 126 new viruses, bringing the total to 852
- total strings. Among the new viruses included are "1024-SBC" and "Peach".
-
- 2. There are no active disinfection routines included in this release.
-
- 3. This version catches attempts to exit VIRx scanning with CTRL-C, and
- requests confirmation. If the user confirms the exit request, VIRx will
- clean our virus signature database out of memory in order to further reduce
- the possibility of "Virus Active In Memory" false positives.
-
- 4. A bug was discovered in scanning files of exactly 1024 bytes that could
- under improbable conditions have caused false positives. The bug was
- eradicated.

- VIRx 2.1 Revisions
- ==============================
-
- Date: 03/09/92
-
- 1. This release of VIRx detects 57 new viruses, bringing the total
- to 726 total strings.
-
- 2. Included in this release is the "MALTESE AMOEBA Virus" disinfector
- from our commercial product, Virex for the PC. The Maltese Amoeba
- infects files, variably encrypting itself to try to hide from virus
- scanners. On March 15th its destructive code will activate, overwriting
- a substantial portion of your hard disk. At that time, it also replaces
- the disk's Master Boot Record with code to display a poem (about a
- grain of sand) on subsequent reboot attempts -- such reboot attempts will
- always fail once the virus has triggered on March 15th. This virus is
- believed to be fairly widely distributed in Europe. The disinfector in
- this release of VIRx is active until March 20.
-
- 3. This release of VIRx no longer includes the Michelangelo Virus
- disinfector; this disinfector and many more are always included in
- VPCScan, a portion of our commercial product, Virex for the PC.
-
- 4. Improved V2P6 scanning has eliminated all known false positives for
- V2P6, including those from older programs, such as MEM.COM and
- POPDROP.COM.
-
- 5. To save your printer paper, some of the earlier "WHATSNEW" entries
- have been removed from this document and can be found in the file called
- "OLD_NEWS.TXT", also in the archive. We encourage you to read this
- file when you have a chance.

- VIRx 2.0 Revisions
- ==============================
-
- Date: 02/07/92
-
- 1. This version of VIRx contains the Disinfector for the MICHELANGELO
- Virus from our commercial product. The MICHELANGELO virus infects
- hard drive Master Boot Records and floppy boot sectors very much like the
- STONED virus. Unlike the STONED virus, MICHELANGELO contains code which
- activates on March 6 and, by overwriting critical sections of the infected
- hard drive, destroys the information on the disk. VIRx will detect AND
- REMOVE this virus if used before March 6, 1992. After that date, VIRx will
- still detect the virus, if present, but removal will no longer be offered.
-
- 2. VIRx detects 20 newly discovered viruses, bringing the total to 669.
