Email links have stopped working in gmail

until last week when I received an e-mail in gmail that had website links in it I was able to click on the link to open my browser ( chrome ) and be sent to the site, this no longer works and I don't know if this is a norton internet security problem or a chrome problem, some family members enjoy entering contests or shopping this way but can no longer access websites by using these links, I am a novice user and cannot find out where the problem lies, I did receive a norton update so suspect that this may be where the problem is but do not know for sure, can anyone help so I stop getting grief from my family!
