AVG Protection

Hi Balasubramanian ,

thanks for the reply.

i'll submit our exe to be added to the whitelist.
one concern i have is that we are constantly updating the software. so we do recompile the exe, will this be an issue? like create even more false positives?

thanks for your time.

Hi Phiroz,
Sorry to know that. May I know the name of the AVG program installed in your computer? To know if AVG is the actual cause of this issue, please try to disable AVG ( http://support.avg.com/SupportArticleView?urlname=How-to-disable-AVG ) and check if you are able to run visual basic compiler.
Feel free to contact us if you have any queries with AVG products. Thank you.

After the recent update,

AVG is block the visual basic compiler from running.
C:\Windows\Microsoft.NET\Framework\v2.0.50727\vbc.exe

my current fix is to add the compiler into the execptions.
as this is part of MS .NET framework why is it blocked in the first place?

Please take a look.

thanks
Phiroz

Hello Phiroz,

Thank you for understanding. Well I strongly believe that it may again detect your application as a threat if you make any change in your program. However let us not come to any conclusion right now. If you face the issue after updating your application please do let us know. Please follow the instructions give before to add your .exe to the AVG program exceptions and send us the sample for analysis. Thank you.

Hello Phiroz,

Thank you for explaining your issue. Sorry for the inconvenience caused. Yes, at time our AVG antivirus program will block some .exe files because it may think that it may harm your computer but however some .exe files will be trusted one and the best solution is to add it to the exception of AVG. Also submitting the sample to us via http://avgread.me/1GgMyPc can help us to add it to our future virus definition updates. Thank you.

Hi Komal, 

thanks for the reply.

So here's my setup.
it's a clean installtion on a VM.
my app runs without any issue before i installed AVG.
After I installed AVG the program has issues.

troubleshooting i've done so far.
disable AVG : program does not have issues.
enable AVG with program in exceptions. : program does not have issues.
disable indivdual AVG components: program has issues.

doing some investigation i find that AVG is blocking vbc.exe (the visual basic compiler).
i've also had feedback from my customers that an eariler build of AVG is blocking other parts of our program. our current workaround is adding the folders into the exceptions. we did not have this issues with previous versions of AVG. 
the build versions we've checked are 2015.0.6140 and 2015.0.6086.

what is supprising is that when it blocks vbc.exe there is no log or indication from AVG that it is preventing execution. which is why i created the VM to specifically to check what was happening, as we've been geting a fair amount of customer complaints.

i'm hoping to see if there's a simpler way to add exceptions or if you have a newer build.
is there a simpler way to upgrade the Program version( other then uninstalling)? 

thanks for the help.
