We have discussed this subject many times in this forum.There is no universal "one size fits all" solution
that works for everyone and there is no single best anti-virus
. Every vendor's virus lab and program scanning engine is different. Each has has its own strengths and weaknesses and they often use a mix of technologies to detect and remove malware. In many cases choosing an anti-virus is a matter of personal preference and what works best on a particular system. You may need to experiment and find the one most suitable for your needs.

Here are links to polls about this very subject:
My personal recommendation is ESET NOD32 Anti-Virus
if choosing a paid for program as it leaves a small footprint...meaning it is not intrusive
and does not utilize a lot of system resources. Emsisoft Anti-Malware
is also a good choice for the same reason and so is Kaspersky Anti-virus
. If you don't want to pay then I would recommend avast! Free Antivirus
or Bitdefender Anti-virus Free Edition
Keep in mind that all free Anti-virus programs now come with toolbars or other bundled software except Bitdefender Free
...see Has the antivirus industry gone mad?!
ESET and Emsisoft Anti-Malware also have the added advantage of blocking the installation of most Potentially Unwanted Programs (PUPs)
(such as adware
, unwanted toolbars
, browser hijackers
) if you enable that feature.
See my comments in Supplementing your Anti-Virus Program with Anti-Malware Tools
as to why I recommend Malwarebytes Anti-Malware Pro and Emsisoft Anti-Malware.
