Depends on how paranoid you are using a Russian product. Russia tends to want to be intrusive on thier bussinesses and reports came out years ago that Kaspersky was in cahoots with the Russian Federal Security Service to scan peoples computers, which Kaspersky denies. I think Kaspersky is safe and many people love them but food for thought. If not at all worried (which I wouldnt be) it may be useful. But, like Ladong mentioned, do you have an issue using the Windows built in anti-virus? It has come a long way and is fairly good, especially if you are smart with what websites you visit and files you download.
I've used the Windows defender and Malwarebytes for years with no issues.
Why do you ask?
For protection from known viruses, the free windows defender is as good or better.
From "in the wild" or unknown viruses, kaspersky does try to keep analyzing your system to detect such.
Most viruses come in via "social engineering"
You need to be smart about what you access.
