I wrote RAC "Remote access Control" (also on this forum) and found the same problem but only if i "pack/obfuscate" my Autoit proggie. Maby you must ask the author of this program if he can compile it without too much protection (that is IF he protected the program). 99% of the time this fixes the "Virus Detection"kayman wrote:The problem is the client is out of the office and trend micro goes strict when in roaming mode and doesn't allow you to change settingsbut when in the office you can specify allow rules

UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12TH

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
Im sure John can answer the above but with my problem Trend isn't detecting it as a Virus its more so the behavior monitoring system that is blocking it, i.e. the helper program launches but as soon as the user hits connect it hangs as the behavior monitoring software is blocking whatever it is trying to do, whether it be making a registry entry or adding the service I'm not sure as I don't know what the app is doing at that point.
Hope that makes sense.

So is it true then, lets say you STOP Trend from running...Then the proggie continues?kayman wrote:Im sure John can answer the above but with my problem Trend isn't detecting it as a Virus its more so the behavior monitoring system that is blocking it, i.e. the helper program launches but as soon as the user hits connect it hangs as the behavior monitoring software is blocking whatever it is trying to do, whether it be making a registry entry or adding the service I'm not sure as I don't know what the app is doing at that point.

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
Sure Does, check my post on last page but basically if i stop the behavior monitoring service it works perfectly, the on access / online scanner can still be running hence not a virus blocking but more so changes the app is making which is not a problem with the application more so the strictness of Trends behavior monitoring service.
Was just updating John as previously we thought it was a problem with the App.

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
Its deff NOT the app that's the prob...What you might also do is, check if Trend(sorry i don't actually work with Trend though) has an option to "disable" HEURISTIC monitoring and turn it off. This way you will STILL be able to detect viruses...Only diff is, THIS way it finds REAL viruses, and not just "make believe" viruses.kayman wrote:Sure Does, check my post on last page but basically if i stop the behavior monitoring service it works perfectly, the on access / online scanner can still be running hence not a virus blocking but more so changes the app is making which is not a problem with the application more so the strictness of Trends behavior monitoring service.

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
Do anyone knows or has an idea how to fix the issue:
--No support for UAC prompts when running as "non-admin"
?
Or any hints where I can go for searching?
I tried to find any information about this or any backdoors but could not find any things.
Is there any possibility to auto fill in the username and password(because I know the username and password) and to klick OK or always to klick abort? I think the biggest problem is that if I call the UAC(but dont want to) and no user is sitting in front of the PC the PC freezes for me and I can not control it any more until someone klicked on "abort".
Any information or hints?
best regards,
marc

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
Wow! My subscription of this thread must have died a month or so ago... so I wrongly assumed this project had died.... (since I didn't get any more notifications - interestingly enough I see John had the same problem around the same time!)
Great to see so much interest in this excellent little program... and also great to see how much progress John has been making.
Anyway, hopefully by posting here again I will start getting notifications of replies again.... (I guess I'll have to wait and see).

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
Mike i think it did it to me again... whatever.. good to see you mike, ive been doing alot of work on the program but ive taken a break, in part to think about the new opening UI i want to create, and also im taking time off from work and vacationing, September should be much more productive.
to touch on the A/V issues and to give insight as to how i build the executable:
----To reduce size the autoit script is only Obfuscated using /striponly, no renaming or tricky script protection.
----The executable it packed using PECompact, this is basicly UPX but not opensource, so the resulting executable is less likely to be detected as a virus
----A stipped down version of winvnc.exe is also (seperatly) compressed with PECompact
----Nothing has digital signatures
it might be worth testing a build that has a non compressed winvnc.exe, i suspect heuristics dont like a compressed executable unpacking and executing another compressed executable from itself that establishes a network connection so quickly.
i just uploaded 4 builds, the first CAPS is what i did to winvnc.exe and second is what i did to the compiled autoit exe UVNC-Helper.exe (note that by signed i mean that i didnt do ANYTHING to it), also note the size, the largest file should be the least likely to be blocked, and the smallest would be the most likely.

marcgistel this is impossible as far as i understand, if it were possible it would mean that UAC doesnt work/has a security flaw

Hi there John!
How it's going with Your work?
You haven't updated this thread for a while, so I'm just curious
Cheers and best regards.

John,
Good to see you back here.
Look forward to making more progress on your great little tool... but it already is real neat and does the job very well.
If you need something specific testing then give me a shout....
Mike

Using your tool quite a bit and is working really well for me. Thanks again and cant wait to see the additions.

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
It seams a shame that we are each making basically the same thing, but seperately. perhaps you would consider rolling some of your code into scprompt ???JohnMC wrote:ive been away from this project for to long
it now has 5different GUI's, service mode options (uses existing uvnc services if found, or makes its own), & much more ...
there are also 3 coders contributing, other than me ... otherwise I would consider dropping it in favour of yours ...
it just seams a waste that we are working in parrallel, when working together would make much more sense ... and make a better app
something for you to think about before you get "snowed-in" & have time to start coding again ...

Hey John,
haven't heard from you in a while, just wondering how the project is going and if we can look forward to some updates?

First let me say that this is an awsome software mate, works wonderful and it's one of the simplest and most powerful solutions 
second I would like to ask you about the picture option in the "embed" function, I didn't see that it did anything, I tried both jpg and gif files and it's still wouldn't load when you start the program, is this feature working or is it just for future updates ?
third I would like to ask about the source code, I downloaded it and tried to build it "as is" before doing any changes and I got 3 errors :
C:\Users\Test\Desktop\UVNC-Helper-SRC-3.1.5.0\_APTGet.au3(165,46) : ERROR: undefined macro.

any idea why ?

Re: UVNC SC - UVNC-Helper - More Than VNC! - Updated July 12
sry for the late relpy, ive been moving, and i plan to make some major improvments to this project as soon as im done..
thank you for the positive feed and to answer your question, yes, it only operates for reverse connections right now, soon i hope to change that and even include some nat2nat functionality.
so to get it to work, just run your viewer in listen mode, and make sure you have the ports forwarded/ your firewall open, then use my program on the remote pc
