I had a lot of these pop ups and I don't know if it's for real or not.

    Correct your date and time. Try if this solves your issue. – Manubhargav Sep 11 '15 at 14:17
  • Based on the screenshot, what made you to conclude that the pop-up is related to virus or some other malware? Consider following the advice noted by @Manubhargav. You can also tap on View Certificate and show us the output of it. Anyhow, which website is it? – Firelord Sep 11 '15 at 14:20
  • That note popped up and when I clicked it, it lead to a site that scanned my phone and said I had malware, that's why I posted it cause I just wanted to make sure. – user126923 Sep 11 '15 at 14:32
  • First make sure your date is correct. Are you sure your date is correctly set and still getting this warning? – Manubhargav Sep 11 '15 at 14:38
  • BTW: As @Firelord already indicated, the popup nowhere talks about a virus. I've corrected the title of your question accordingly. – Izzy Sep 11 '15 at 14:49

Solution: Correct your date, or Set the clock to update automatically

Reason: This security warning pops-up when the verification of certificate needs to be done but the requesting system is set to wrong date(usually to the past).
The security certificate is seen as From Future.
This is all related to certificate validation by the browser.

NB: This does not harm your phone (and certainly it's not a virus)

EDIT: There can be other reasons as suggested by @Lie Ryan - due to certificate mismatch / weak encryption / browser not trusting the CA

    There are other possible reasons why you may get invalid TLS/SSL certificate warning other than expired certificate (or certificate issued to future date). The certificate may be issued for a different domain name than the server you're trying to connect to, or it may use a weak cryptography that are no longer trusted by the system, or it may be issued by a certificate authority that the browser doesn't trust. In any case, you may want to view the certificate and find out what's wrong with it. Or bail out to safety. – Lie Ryan Sep 12 '15 at 14:29
  • I didn't understand the reasoning for revision 4 and revision 5. Would you please care to explain a little? – Firelord Sep 24 '15 at 11:13
  • @Firelord I thought it was not necessary to mention about virus since the original question was edited removing the term virus for revision 4. But then I thought it will help readers further to understand that android does not suffer from virus problems as many posts about virus have come up in the recent past, hence revision 5. – Manubhargav Sep 24 '15 at 11:22
