Short: V1.68 Check for Archives/Packers/Viruses Author: stoecker@amigaworld.com (Dirk Stoecker) Uploader: stoecker@amigaworld.com (Dirk Stoecker) Type: util/arc Requires: util/arc/xadmaster.lha util/virus/xvsLibrary.lha util/pack/xfdmaster.lha util/pack/xpk_User.lha Version: 1.68 This program uses xfdmaster.library (see util/pack/xfdmaster.lha) and xvs.library (util/virus/xvsLibrary.lha) for packer and virus scanning. The xadmaster.library (see util/arc/xadmaster.lha) is used to dearchive file and disk archives. NOTE: xadmaster.library is Shareware, so think about registering when using this utility together with that library (and without it's nearly useless). See conditions in xadmaster.library distribution. The xfdmaster.library is needed to run the utility. The xvs.library and xadmaster.library are recommended! The xpkmaster.library is needed with ASKPWD password only (and to decrunch XPKF files). CheckX unpacks archives and packed files as deep as possible: - you can unarchive a crunched archive as well - multiple crunched files can be decrunched - multiple archives can be extracted - multiple disk archives can be extracted - linked and crunched and archived files are no problem This all depends mainly on your memory size! If have around 50MB and have only little problems with really large files. Call CheckX with a ? and you get following argument list: FROM,LOG,SAVE/K,ALL/S,ASKPWD/S,AUTOMOUNT/S,PRINTALL/S,PRINTEXEC/S, NODECRUNCH/S,NOUNLINK/S,NOUNARCHIVE/S,NOUNTRACK/S,NOTRACKCUT/S,NOSTRIP/S, NOVIRUS/S,DEBUG/S,QUIET/S Enter a ? again and you get a short doc: FROM source file or directory - may contain patterns LOG log file name SAVE directory, where decrunched files are saved ALL scan deep into directories ASKPWD ask for password when needed (needs xpkmaster.library) PRINTALL print all filenames PRINTEXEC print names of all executable files AUTOMOUNT automatically mount RDx: device when needed NODECRUNCH do not decrunch files with xfdmaster NOUNLINK do not unlink files with xfdmaster NOUNARCHIVE do not call archiver for unarchiving file archives NOUNTRACK do not call archiver for unarchiving track archives NOTRACKCUT do not call archiver for partially track archives NOSTRIP do not strip useless hunks NOVIRUS do not scan with xvs.library for viruses DEBUG also output texts to serial debug engine QUIET do not output texts to console A bit more explanation: LOG The output is written to a file as well as to the standard output stream. The main purpose CheckX was written for is to scan for crunched files and to test the decrunch routines. So the logging may take some more time, but is very stable, as the last log-entry is always the file which possibly crashed the machine. The logfile can be accessed by other programs for read and write the whole time CheckX works (and surely after that). But writing is not recommended, as this may produce a corrupted file. SAVE If this keyword is given, all uncrunched/unlinked/stripped files will be saved in the directory given with that keyword. The directory must already exist! Sub directories are created automatically. If files are unlinked, they get saved with .1, .2, ... extensions. Address crunched files are not saved. Use xfdDecrunchAddr or xfdDecrunch to do so. AUTOMOUNT To unarchive disk archives (DMS, Zoom) a destination device is needed. These devices are called RD0: to RDn: and for high density disks RH0: to RHn:. CheckX can automatically mount these or you may mount them before calling the program. The number n depends on the archiver depth, so normally RD1: should be the highest one really needed. NOTRACKCUT This prevents unarchiving of cutted archives. Splitted DMS-Archives may produce strange errors, but can be checked correctly, when the two parts are directly after another (e.g. no other track archive is between them). In this case the first file shows some XPKCERR_READWRITE and the second one the correct stuff. I checked EuroScene1 CD which has a lot cutted archives and newest xfdmaster.library had no problems, so probably this option is not needed anymore. DEBUG Should not be used normally. This brings the normal output to serial debugging terminal or catcher tools like Sushi. This allows a lot easier to detect files producing hits. CheckX has following return values: 0 - all ok 5 - either no virus checking possible or virus found 20 - an error occured and CheckX was unable to do anything CheckX cannot scan files, which are read-protected. You get CheckX error 4 as result in that case. Unprotect files and scan again when you want. For files contained in archives, the protection bits are ignored. CheckX is completely reentrant and may work fine twice or more times parallel (You can set the pure file protection bit and make it resident), with one exception: Destination Disks (RDn: or RHn:) can be accessed only by one tool! So when source path contains disk archives, start only one copy of CheckX or use NOUNTRACK! It is not recommended to call it multiple times as CheckX normally needs lots of memory. This is a batch tool, so drink a coffee or two or three during its work. Check the logfile afterwards. Use a text-editor and scan case sensitive for "-Virus" and you get lines which a related to viruses (and mostly only the important lines). A scan with "XFD-", "XAD-", "CheckX-" or "-Error" brings lines which produced errors. The complete number of found viruses is logged at the file end, if the scan found some of them. Also the scan time and the number of errors (if some appeared) is logged. If the permanent file scrolling slows down your computer try setting the output stream to a raw mode display using following redirect command: ">RAW:0/11/640/50/CheckX-Output/AUTO/CLOSE/WAIT". To get CheckX really silent either use LOG option and call CheckX with QUIET or redirect normal output into logfile with ">filename". CheckX detects all the viruses found by xvs.library, which contains the complete antivirus knowledge of VirusZ utility by Georg Hörmann. CheckX cannot detect viruses in memory or remove detected viruses. You still need antivirus software like VirusZ, VT or Virus_Checker. I always run VirusZ in the background to check for viruses. CheckX also scans disk archive information texts for packers and viruses and also bootsectors of dearchived disks. Error 11 (Could not check for virus) mostly means, that the files is a bit to large and such files are normally archives only. So in most cases this error is harmless! If there are serious errors, please report them, but CheckX has a long way of development and I hope it is really stable now (as well as xfdmaster.library is now). Send me files, which cause the system to bring Enforcer/MungWall/PatchWork Hits or crash the computer. If the files are larger, please contact me first. This program is Freeware.
