I running KIS 2017 and F-secure IS 2017 on my 2 laptops (with W7 and W8.1). I dont have any problems with this
installations: everything is running fine. Currently KIS 2017 is running on my old laptop (i5,GT540M,

4GB RAM, about 9 years old): i want to remove it and then install it on my second laptop (i7, GTX970M,

8GB RAM) that has much more resources/performance.

My question is:

Both AV manufacturers are offering removal tools. Is it absolutely necessary to run removal tools to properly remove both AV-products ?
...or is it OK to simply uninstall both AVs (via the control panel-> Uninstal programms) without running removal tools after the

regular uninstallation process?

Anti-virus software components insert themselves deep into the operating systems core where they install kernel mode drivers that load at boot-up and create numerous files, folders, and registry entries in various locations making it more difficult to remove than most applications. It is not uncommon for some anti-virus programs to not completely uninstall itself using the usual method of Apps & features in Windows 10 or Programs and Features (Add/Remove Programs) in Control Panel or to result in various errors due to the presence of related services and processes running in the background.

In some instances uninstalling may fail, not work properly or result in continued detection by another anti-virus program after removal. Most anti-virus vendors provide clean-up utilities or removal tools on their web sites to remove remnants left behind after uninstalling, or for a failed uninstall or failed reinstall.

So to answer your question, no it is not always necessary to run the vendor created removal tools. However, I typically use them anyway to ensure all the remnants have been removed. Remnants include related registry entries, files and folders created in various areas of the OS. Performing an uninstall via Apps & features/Programs and Features in Control Panel does not always do a thorough job.
