We have made some improvements to F-PROT since the release of the previous
version:
The program now scans for JavaScript and VBScript viruses (including
those that are embedded in .html files), as well as .BAT-infecting
viruses, mIRC viruses (INI infectors) as well as the first .INF file
infector and both of the known .SMM viruses, which infect Ami Pro
documents.
We have added heuristics for 32-bit Windows viruses, which should
detect the majority of new such viruses. There is a possibility that
those heuristics may generate false alarms, so any unexpected reports
of possible unknown viruses in 32-bit Windoes executables (PE files)
should be confirmed.
Some viruses will replicate only in compressed form (LZEXE, DIET or
PKLITE), and if the infected files were unpacked, F-PROT might not
find the virus, as it only recognized the compressed version. This
was not a problem for users, as the unpacked viruses did not
replicate, but this was a problem for us, as such unpacked viruses
have found their way into various virus collections used for testing,
and our failure to detect the (non-replicating) samples gave us an
artificially low score. We have now changed the way we detect those
viruses to prevent this from happening.
The program can now scan for boot sector viruses in .TD0 image files.
We have speeded up the scanning of many files that we had been sent as
they took unacceptably long to scan.
Some problems were found and solved after version 3.03 was released:
We solved the problem when running F-PROT under NT, which was reported
in the PROBLEM.TXT file in version 3.03, when the scanner quit too
early when scanning a huge number of files, such as a virus collection
with 130.000 infected files (which is the real-life situation where
this problem was first encountered).
We have of course added detection/disinfection of more viruses, bringing
the total number of viruses and destructive programs that F-PROT
recognizes to over 23900.
