Here’s a long term (perhaps very long term) item maybe for your roadmap…
There is of course a trend to run as much functionality as possible as kernel modules…
Not only would that solve certain security issues (limited access by other processes) you might experience performance gains and perhaps be able to re-use code that already exists in the kernel (for example, I can imagine scanning a file system might be possible with functionality that’s already part of the filesystem).
The obvious downside is that AFAIK any kind of kernel code (likely beginning with a kernel loadable module which can be manually activated, loaded, removed, etc) would have to be written in C. But, let’s say that today you’ve done a good job of modularizing your existing script code. If you can make use of filesystem functionality, maybe your original code would actually be very little, piecing the functionality together and not so much creating the functionality.
In any case,
loadable kernel modules can be surprisingly easy to write… There are a few YouTube videos (less than 15 minutes!) and various documentation that can give you the basics.
Looking back, the original purpose was to fill in the gaps in functionality in clamscan. Simply put, adding level of features it lacked or simplify the functions. Noting the desktop apps that have a clamscan engine, you can’t use them if your desktop is corrupt. No desktop, no problem! Even works on a server. Scan flash drives and your main system at the same time. All ideas are from my own needs. Not to mention, I use lots of free software. It’s my chance to give back something.
I’ve been trained in structured programing. Modular functions are part of my skill set, seeing that formal training.
I know c programing, but with bash you don’t need to that complex task of compiling code. Bash is slower, but it’s copy and paste into /usr/bin/ (overwrite file yes) then it’s ready to use.
My code is so streamlined. You should notice almost no time before scans start. Many times, I ran a low-priority scan on slow laptop. The laptop scan was only as slow as the clamscan engine.
Security, bash is already opensource. Anyone can open the text file. It’s well commented and lots of white space formatting for readability.
I might write in c later, just for speed. However, bash is easier to code. As of now, I still can’t figure how to compile the clamscan code, “WARNING: Your ClamAV installation is OUTDATED!”.
Converting this monster size code to C will take a long time! For now, I want to compile the clamscan code. For another topic…
Don’t upload this anywhere! Official release will like have hidden fixes and upgrades. Only available for 1 day.
Beta3 Test version:
Scanlogs upgraded. Total scan time added. Code streamlining to follow. To scanlogs, possible fields ordering in config file.
FYI: lock screen sometimes will block the suspend command.
Ignore:
No such file or directory
WARNING: : Can’t access file
Bash error on last line of code, random.
READ ME! Config file has been changed. Erase old ‘scanvirus.cfg’, using ‘scanvirus -vf’. Then do ‘scanvirus -v’, a quick way to do reinit. ( I use this method. )

date +‘%Y-%m-%d %I:%M:%S%P’
DateTimeStamp= %Y-%m-%d %I:%M:%S%P

Again, don’t upload it anywhere! This does some fixes and upgrades. The next one should be final one, before the stable release. Available for one day only. Only ‘virus’ or ‘clean’ now. New additional cfg options. Not fully tested. Note any issues or bugs here.
In-progress: i’ve been working on a configurable scanlog line, simular to printf.

date +’%Y-%m-%d %I:%M:%S%P’
TimeStamp= %I:%M:%S%P

I’m almost ready to release betatest5. I may separate the background command from suspend and power-off. I need to run more tests as well.

I’ve done many tests on linux folders and a full scan. I’ve done quick tests on mswin scans. I will do doing be mswin full test, all night. If I keep it, the partition log{} will be in both mswin and linux scan logs.
I’m doing heavy bug testing to ensure this stable v1.00 release has NO BUGS! This is reason for the delays.
I’m starting a total conversion from bash to c code. It’s going slowly, scanvirusbin. I’m almost done with the init code. I just need to write cfg file reader. The security will be much better.
I have another idea. A new line function for scanlog. A needed if error check for reading in varible names from cfg file. If any var is null, the function exits.
I’ll post, hopefully, last betatest version soon.
Any suggestions welcome…
I might add the ability to change the special character.
The character associations should be changed, but I don’t have any ideas yet.
This is betatest7. I have only one feature left to add for the open release. Adding newlines to scanlog will cause the search to fail. So, this function will not work.
Only available for one day for testing. I added a feature to detect missing variables in the cfg file.
