You can, but it is not recommended nor needed. As long as you are using a good antivirus program a second one is not needed.
Running two antivirus problems will use additional memory and CPU power to provide little to no additional protection.
Some of the larger antivirus companies (Symantic specifically) are extremely bloated software and often don’t play well with others.
My answer is definitely no. Although sometimes it is possible to install to virus software, it could create a freezing computer system and sometimes too much slow performance. Remember that an antivirus software constantly scans the entire hard disk drive of a computer system and simultaneously protecting it from portable devices. Imaging 2 large software scanning the entire computer system’s hard disk drive.
