Sending TCP packets to many IP addresses after downloading a program

Question

I constantly monitor UDP and TCP packets sent to IP addresses on my Windows 7 computer. After downloading a free online program to convert media video files, I soon noticed my computer constantly and rapidly sending out packets to more
than 10 IP addresses (and quite a few were going to China, Russia and Germany). I tried a search on my hard drive for the file that contained those specific IP addresses and found nothing.
Note: For Viewing Folders, I do not hide operating system files, and I show hidden files, folders and drives.
Then I  tried searching my windows registry (via REGEDIT) for those IP addresses and found nothing.
I assumed these IP addresses may have been hidden and included in a .dll file. I could not find an answer on the internet to determine where these hacking IP addresses originated from, so I deleted the program and rebooted.
The problem still existed, so I had to restore to a previous backup date. The restore fixed the problem.  I am so confused. If I wasn't monitoring my connections I would never have known about this hacking flaw in Windows 7 security. I
still don't know what type of file(s) were causing this problem. Or what causes my computer to send unsolicited packets to so many IP addresses (to domestic, foreign and hostile locations).

Contains malicious code.
Thank you FangZhou Chen for your response. I am not exactly sure which of these two programs (listed below) was the culprit for this problem, but I do know that both programs have issues with malicious code. Understand I have used both of these programs
in the past, but stopped using them because of these issues. The Freeware #1 was my favorite and was user friendly, until the malicious code was added, and may be the real culprit.
Malicious Freeware #1: Any Video Converter (program name: avc-free.exe)
This program contains PUP.Optional.OpenCandy - While PUP.Optional.OpenCandy is not technically a virus, this PUP can be extremely annoying and quite difficult to get rid of. It comes loaded with adware, which as anyone who has been infected by adware can tell
you, can drive you to the brink of insanity with its relentless adverts, plus it will very likely hijack your browser and install a strange and unwanted toolbar on your machine too. Not only do unwanted toolbars get in the way but they can direct you to websites
that the creators want you to visit and can in general make using your computer a real user-unfriendly experience. PUP.Optional.OpenCandy is also a form of spyware which enables it to be installed deep within your PC’s operating system so that it is harder
for you to find – and therefore delete.

Malicious Freeware #2: SUPER © Media Converter Encoder
This program is bundled with other software. I don't remember the malicious type or effects.

P.S. - Excellent tools in cleaning up maleware have been to use Malwarebytes, AdwCleaner and  HitmanPro (both recommended by the malwarebytes.org website).
