One of the reasons I hate McAfee ***answered***

And I will not renew at sub-end.

I write little scripts to run at the command line because the programs are cmd line programs.  I added a simple Print #1,"timeout /t 1".  And all hell broke out not at compile or save exe, but at execution of the exe.  I thought I was dreaming.  I commented out the line and it ran clean.

I hate McAfee.  Except for a nice VPN bundled product, I can not recommend McAfee.

Be wary, be warned.  reason runtime virus detect

----- more complex -----
I tried to simplify the error.  A simple program just writing out my error line "timeout" does not fail.  The total program as a whole must have some timing issues which trick McAfee into flagging it.  I still hate McAfee

OK, I cheated I fix my problem, but the basic (not qb64pe) still exists.  My fix I broke up the problem into two lines not one:
Print #1, "timeout";
Print #1, " /t2"

I hate doing it that way.  But any kludge that works is 100% good programing.

Since Windows 8, you no longer need a third-party security program; Defender is sufficient.
Where are your programs running?

It works fine for me. I hope so.

once on windows10.  without third-party anti-virus nor any other "internet security suite."  i wrote a simple program.  with qb64 to copy files.  because the executable had "copy" in the name.  windows refused to execute it.  was forced to rename my program.  if i had a ghost of a chance of running it.  although it was quite harmless.  since windows7 repeatedly upset me in such a short time.  i didn't even care what was in "program files" directory.  except of course stupid installers by greedy companies.  obligate the user to check in there once in a while.

I am running a png compression program.  Only runs at a dos cmd level.  Since I have the horsepower I run multiple cmd windows via a script written in QB64pe. I am also using a program called cmdow.  It can do a whole lot of things to win ... windows.  After a windows update.  The launching of cmd windows got faster.  The windows (10 of them) did not resize and reposition.  Adding the timeout to the script fixed that.

I am running McAfee because it was free with the computer and it's got a very good VPN bundled.  Only renewed once, not renewing again.  I find out I don't really need a VPN.  The only VPN I might need at work is a VPN Tunnel.  Nothing like the VPN snake oil being pushed today.

McAfee is not my favorite either. I signed up years ago for their service and didn't renew as there were more cost effective programs. McAfee then hounded me for years to renew, when reduced offers were refused they became more aggressive in pursuing a renewal. They no longer send me anything, so happy the sales pressure is no longer.

Final answer from me on this subject.  My little two line trickout, doesn't work now.  I had to exclude my compiled qb64pe program from McAfee scanning.  Hopefully they only look at the name, not date and size too.  I may need to make changes, now and then.

I second KernelPanic's suggestion. Windows Defender is more than sufficient for virus protection. I haven't had a third-party antivirus installed in years, except for my work computers, which use Sophos. Windows Defender used to be nothing more than just the absolute bare minimum protection, but it is definitely a competent antivirus now.
