I was in need of a program which would scan for viruses inside
|
||
|
|
compressed files on my BBS. Since I knew of no such program, I sat down
|
||
|
|
and wrote ScanAll.bat and its companion, ScanArc.bat. These two batch
|
||
|
|
files accomplished my goal so elegantly that I thought I'd submit them
|
||
|
|
to PC Magazine for publication. As luck would have it, though, I was
|
||
|
|
going through a back issue of the magazine and discovered that someone
|
||
|
|
had already submitted such a concept, albeit with a different approach.
|
||
|
|
Oh, well. That's the story of my life.
|
||
|
|
|
||
|
|
To use these batch files, simply put them in a path and change
|
||
|
|
to a subdirectory which contains compressed files to be checked.
|
||
|
|
|
||
|
|
Type: ScanAll <enter>
|
||
|
|
|
||
|
|
then sit back and watch the magic.
|
||
|
|
|
||
|
|
ScanAll.bat first checks the directory for any and all compressed
|
||
|
|
files by looking at the files' extensions. It then passes each file to
|
||
|
|
ScanArc. ScanArc creates a working subdirectory then uncompresses any
|
||
|
|
EXE, COM, or OVL it finds. Then ScanArc calls SCAN.EXE to scan for
|
||
|
|
viruses. If a virus is found, ScanArc will rename the original
|
||
|
|
compressed file, giving it an extension of "BAD". It then logs the
|
||
|
|
activity in a log file called ScanArc.log and proceeds to the next file.
|
||
|
|
ScanArc will also update the log when no viruses are found or when
|
||
|
|
SCAN.EXE terminates abnormally.
|
||
|
|
|
||
|
|
ScanArc.bat can also be used on a single file by passing it the
|
||
|
|
name of the file and the name of the decompression program.
|
||
|
|
|
||
|
|
e.g.: SCANARC foo.lzh lha <enter>
|
||
|
|
|
||
|
|
The compressed file must be the first argument to ScanArc.bat and the
|
||
|
|
decompressor must be the second. You can rearrange the dummy parameters
|
||
|
|
in ScanArc.bat if you don't like the precedence of the arguments.
|
||
|
|
|
||
|
|
CAVEATS:
|
||
|
|
|
||
|
|
ScanAll and ScanArc will not check for compressed files inside of
|
||
|
|
compressed files, nor will they make note of such. Also, LHA will give a
|
||
|
|
benign error message when it can't find any of the target files to
|
||
|
|
extract. This causes no harm, but I couldn't find a way to shut it off.
|

Please let me know if this program is useful to you by logging onto my
|

|
|
BBS @ 602-881-3769 24 hrs up to 14.4k. Or send net mail via Fido net
|
||
|
|
address 1:300/8. This is my only way to travel.
