Microsoft has announced the end for XP support as of April 2014. There will be no more security updates after that. I believe Microsoft is serious about ending XP support.
However, many businesses will still be running XP after April. Those of us who maintain PCs will still need to work on them. It would be nice to have a supported anti-virus product.
Will Symantec continue to support AntiVirus and Internet Security on XP after next April? Has an official policy been announced?
