Update it once the installation is complete to have the latest virus definitions and then configure it for your email client. Restart your computer again and then install Norton AntiVirus back. Check “Temporary files” and “Setup log”, click OK, and then click Delete Files. Next, click Start, All Programs, Accessories, System Tools, and then click Disk Cleanup. Try uninstalling Norton AntiVirus and then restart the computer. Since the error has something to do with the antivirus’ resources which seems to be unavailable, make sure the program is installed properly. It makes sure that the message you are sending is clean including the attachments if there are any. When you send an email using your email client, Norton AntiVirus scans the message before it leaves your computer.

Just like what it does with your computer that monitors for any malicious activities, it also checks malicious attachments on emails when using an email client especially checking for spam mails. I usually encounter errors while using Norton Internet Security as well as Norton AntiVirus but since I’m not using an email client before, I haven’t encountered this error yet. If there is a way to dispute or report invoices then it should be much easier to access, and if there's not then it's a pretty glaring hole in terms of fraud prevention (which scammers are already swarming to take advantage of).Norton antivirus unavailable to open emails

Maybe I'm missing some mechanism to deal with this, but as far as I can tell there's no way to deal with / report this obvious scammer, and even though I didn't fall for it that doesn't mean that less internet-savvy folks out there won't. Despite this apparently being a pretty prevalent problem I can't see any way to report this invoice as fraudulent or to report this PayPal account? If I try to report the transaction via the Resolution Center I get an error that these types of transactions can't be dealt with there. There is also an article about the recent uptick in these specific scams here.

This is obviously a scam, the sender of the invoice is some random guy's name and very much not Norton Security, to say nothing of the fact that I've never bought antivirus software in my life. I recently got an email and phone notification about an invoice from Norton Security.
