Windows 7: Paypal security certificate error

Can I make a suggestion? Check that the PayPal site you see is not a spoofed site due to malware on your system.

Do this to verify the PayPal site unique fingerprint:

1. In IE, on the main PayPal page, click the padlock.

2. Now click 'View Certificates'

3. In the panel that opens, click the 'Details' tab. Scroll to the bottom and click Thumbprint. Compare the thumbprint code to the unique fingerprint (thumbprint) code of the authentic PayPal site as provided on Steve Gibson's site.

This is the fingerprint of the authentic PayPal site:

Code:
21:77:48:25:DC:4A:9C:54:CE:02:B0:70:92:8A:2E:72:CE:58:78:E7
If your panel thumbprint in step 3 matches this code exactly , then the PayPal site you are connecting to is authentic.

Of course you can, and a very good suggestion it is too

Ok Folks. Here's the thing: I tried disabling Java (I'm still suspicious) but that didn't work either. I ramped-up the settings for a full KIS scan (I didn't know default was not the highest) and left it alone while it scanned just under 1,000,000 files. Nothing! Dave, you suggested Windows Defender Offline as a virus scan, do you think it is worth trying that when KIS found nothing and all of the following applies?
I tried the above from Golden (thank-You) and the codes don't match. This was what I got:
e3 ac 7c b1 69 30 59 63 a6 66 7c d4 b4 55 6e 41 6a 34 cd 5c
as you can see, it bears no resemblance to the thumb you sent me. However, in order to log onto PayPal I need a code texted to my mobile that only lasts one minute. I have also received three emails from PayPal (one of which is included above) plus, it is only when I look at my transactions that the error screen appears, everything else on the account page opens up fine. So, I really don't know why those codes don't match because everything about the site appears kosher to me.

I've been trying to access 'My Profile' on the main account page and I cannot. Something dawned on me: my account is an American account opened many years ago in US$; I wonder if I am split between two locations and the American site has a different code.

Ok I just ran Goldens suggestion above and my codes matched exactly.

If yours doesnt match then it looks like your paypal site could be "spoofed" as Golden put it, due
to Malware!!

I would run MalwareBytes again, making sure you have the latest version installed and fully updated,
then perform a full scan. Quarantine anything it finds.

Yes I think you should run WDO it wont harm.

Question:I find it strange that you need a code text to your mobile? Unless thats added security?
I can log onto my Paypal with just my Username and password, Im a tad baffled?

cheers

I logged on to your link and looked at the code and it is the same one I always get and not Steve Gibbon's.
Also, when I log out and the site tries to re-direct me to the open Home-page the error warning comes up again.
The SMS text to my phone has been in place for quite a few years as a security failsafe. As I said, the code sent only lives for 60 seconds. I've sent another email to the PayPal guy who sent me that last response I posted.
Something very strange is going on; the more I confirm my own computer's security the stranger it all becomes.

I agree, but sercurity could be compromised due to malware/virus.

Run the tests and see what the results are...should be interesting.

I've just logged onto my PayPal account using my tablet and received my SMS as normal and didn't find the fault; everything on the page worked fine so there is something nasty on my computer. I'll run WDO but the updated MB didn't fix it yesterday so I don't think it will do any good.
