Never had so much problems changed from Norton to the above and now IE9 crashes quite often which i would not expect from it....any ideas?

Though I haven't seen anything specific for the latest Java version, McAfee is notorious for compatibility issues in general.

I would reccomend moving to a better quality Antivirus such as AVG or Security Essentials, both avaliable free.

or maybe try another browser?

We used to use the above on our computer, until about a year and a half ago when we caught a mean virus, and they wanted even more money to fix it. Changed to another one (that I'm apparently not allowed to name) and now anytime we do catch one they fix it for free, part of the subscription.(which definately is not free)

i also had mcafee a few years ago and it caught a rogue virus what keeps coming up with buy fake anti virus, it broke because of that.

so i would recommend changing too.

our virus wanted us to subscribe to something too! lol

I had mcafee on my old acer computer, it seemed okay but i only had the computer for just over a year and then it broke. I was told the motherboard had gone and it would cost to much to repair, seemed very weird considering it was only a year old.

found this link, not sure if its what you looking for but might help point you in the right direction

mcafee is useless- trust me- im doing a course at the moment and the guy teaching us is an absolute genius-----his tip to me for free anti virus - is if i remember correctly -File-hippo...............its supposed to be the best free anti- thats out there ,,if ya dont like - dont use it

Use AVG, it's probably the best out there! And it's user friendly! Can easily navigate through it and also off the subject if you got a smartphone download AVG free on that aswell, just to make sure it's safe (Phone banking and all that stuff)

See I don't use them as I can protect my own PC and it's more fun finding/Removing yourself if/when you do get something

But Mcafee, has always being a pain when it comes to other programs I used to find it would block certain stuff for no aparant reason.

Also if youwant to get a AV that you pay for NOD32 is pretty impressive and does a really good job and once again the security level on it is immense, but with any Antivirus there are people out there just creating things to get through it so it's not always the Manufacturers fault if something gets through as themselfs need to find it before they can make a fix so it can be stoped etc.

also i have noticed that since i installed it (mcafee) MSE is also running...both are doing real time protection could this be the cause.
