That is a question that will vary from user to user and you will get a variety of opinions. Generally speaking, system performance will depend on the specs of the operating system and other applications/security programs running in the background as well as the anti-virus. Almost any anti-virus installed on an old system or a system with too little RAM or a slow CPU processor will negatively impact performance and have resource management issues. Some vendors offer various features that can be enable or disabled while others offer integrated suites so depending on what you are going to use can also impact resources and overall performance. The impact of an anti-virus on newer computers will be less noticeable and not appear intrusive even though it may utilize a lot of resources without you being aware. Well known vendors like McAfee, Trend Micro and Symantec are designed more for use on high-end and newer computer systems which can handle the resource demands they impose.

My personal choice is NOD32 Anti-Virus if choosing a paid for program as it leaves a small foortprint or one of the following if choosing a free alternative.
