How To Remove The Properties Options

As the tittle says,I want to remove the properties feature because the feature isn't something I want to install.

Perhaps is caused by rootkit,however my ESET doesn't detect anything.

Look at screen-shot below,the properties option that I highlighted is what I want to remove,but I dunno the way to remove properties option. location where the properties feature located then I want to remove it as soon as possible. I try other AV because I just want to remove the option manually.
