Notice to update virus definitions. Is it legit?

I'm getting a random notice in the lower right corner of my screen. (Windows 8.1) that says "virus definition files are out of date. you should update them" with a link to update. That's all that's on the notification.  The rest is just a white background.  I'm afraid to click the link.  I'm running the free version of AVG and AVG says it's all up to date.  Windows Defender is turned off. I tried a restore point, but it's still popping up.

I ran Malwarebtes and it found some pups which I removed, but I'm still getting the popup.

Any ideas how to tell if this is legitimate?  I'm afraid to log into anything secure while on my computer.

Thanks!

Steve

Allow your Anti Virus application to update itself naturally , and if that does not clear the message , scan with Malwarebytes

Thanks for responding so quickly.  The AVG program says it's updated.  I ran Malwarebytes and cleaned up everything it found, but I'm still getting the message. If there was a way to tell what program is generated the message or what the link went to without clicking it, I could figure it out.

If you have found viruses and Malwarebytes did not remove them you could try TDSS Killer (Kaspersky) to clear out root kit viruses. Otherwise you may need to back up, format, and reinstall Windows

I'll try Kaspersky, but Malwarebytes removed everything it found.  Other than the notification to update virus definitions, the laptop is running fine.  I'm just concerned that the notification might be malware trying to get onto my computer.  If I could figure out how to tell what program was generating the notification, then I'd know how to handle it.

If you are sure all is well and free of viruses, you could try a Windows 8 Repair Install to correct the issue.

TDSS Killer didn't find anything.  If Malwarebytes cleaned everything it found and TDSS didn't find anything, can I be fairly certain there are no viruses on it?

So then try the Repair install if you are still getting the warning.  Or, uninstall your A/V, restart and reinstall it.

I was avoiding the Windows reinstall since I didn't want to reinstall all my apps. But the directions look like I can do it without needing to reinstall all my programs.  Am I reading this right?

I have done a Windows 7 Repair Install and kept everything and numerous Windows 10 Repair Installs (easy) and kept everything but not a Windows 8 Repair (never a need in the short time I had Windows 8).  

Back up your data, make sure you know where your software is and then follow the directions very carefully. They should work for you.

Could you screenshot the message?  That's probably the quickest way to tell you if it looks like a genuine pop-up.

Thanks for the help.  I uninstalled AVG and reinstalled and the message is gone.
