Hello, I get what seem to be FALSE Security Certificate Alerts at certain websites I know and trust. Such as checking bank balance online, I receive a: "site not trusted alert."
Another example: I open "Weatherbug" web site: I get similar "windows" security alert warning. I can't make sense out of the warning explanations, nor make warnings go away. What's up? Am I vulnerable to attack?

I completed a very thorough Virus & Malware check through "What The Tech". A few issues were fixed but nothing we did could eliminate the apparent false "security alert" warnings. Thank you for any help resolving.

Hi Jim,

Its an interesting problem you have there, but its good to know that your computer has been checked by Marius and found to be clear of malware.

1 You seem to have covered all the usual things, but errors of this sort can sometimes be associated with an incorrect time stamp or incorrect time zone. I glanced at some of your logs and think I remember seeing that your time stamp is correct… however as a first step please double click on the clock in the bottom right of your screen, check all the settings, time zone etc and if incorrect alter accordingly.

If still no joy then:

2 Try re-setting Internet Explorer …..(and use IE for the time being…. make it the default browser) Tools>Internet Options>Advanced>Reset (make sure all security and privacy tabs are set to "default"
You will need to close down Internet Explorer wait 30 seconds and then reopen it to ensure the changes have been "entrenched."

3 If still no joy then try adding your banking website to the "Trusted Sites" on Internet Explorer.

4 Please be sure that all Windows updates are installed (this is really important as many changes have been made to security settings by Microsoft that could affect the errors/warnings you have been receiving) check by running Windows Update …..install any that are shown as available and reboot and then check for any more new updates….(you may have to do this a number of times to ensure that all Windows Updates are installed) Keep updating and rebooting until you get two consecutive notices (after rebooting) that "no further updates are available"

5 The issue of performing a repair install of Windows (preserving data etc) is also interesting!
Microsoft Windows XP media centre installations discs (there are two of them) are scarcer than hens teeth!(This particular operating system was usually installed at the factory and no seperate discs were issued)

A competent local computer technician will have a set but may be a lttle reticent on where they came from!… :D There is a chance of course that you have a chum who has a set of discs that you could borrow to perform a repair install (you would need to enter your own Product key from the Certificate of Authenticity usually attched to the bottom ort side of your computer.) however its fairly unlikely you will be able to borrow some disc locally… :(

6 If you have a good disc image made when the machine was running fast and sweet (made with something like Acronis, Ghost, Paragon, or Macrium etc.,) as you should, then maybe now is the time to dust it off…?

7 There is usually a restore Partition of Windows XP media centre editions that will format your drive and reinstall the factory image so the computer will be just as it was when it came out of factory…… you will have a lot of work to do, in reinstalling programmes, service packs and updates etc (approx 8 years worth!)

8 The restore to factory is not to be undertaken lightly….. in the workshop to reinstall and update everything is a full days work so, in the home, allow much more time…PLEASE NOTE THE PROCESS IS DESTRUCTIVE AND ALL YOUR STUFF WILL BE CLEARED….(a good accurate and 100% up to date back up of everything on your computer that is important to you is vital. Back up everything you don't want to lose, and make sure you have at least one extra copy kept safely off site on removable media.

9 As you know Microsoft is ceasing support for Win XP on 7th April next year and it will then be unsafe to use it on the internet and for banking or other confidential matters without taking extra special precautions….. to all intents and purposes for the ordinary user it would be as well to upgrade/purchase a newer machine/operating system well before this time, in order to arrange the transfer of documents, data files, worksheets, music, photos etc and to become familiar with a new method of working.

Post back if you need any clarification and let us know how you get on.

Hi paws, thank you for looking at my situation. I performed 1 - 4 of your suggestions, but stil get the (false) security warnings. I'll be away, but back Sunday the 29th to take another crack at the problem. Re-writing the system s/w is daunting. H/P docs I got with system told me to make recovery and "tool" CD & DVD which I did. Maybe I'll see if those might provide a more benign fix. Or, I'll give up on this issue and use a spare XP PC for banking. Thanks, Jim
Try Firefox, see if the same problem occurs. Also, running System File Checker may be a good idea but you would need the Windows MC disc if there are any problem found.
Hi piechase,

An experienced malware removal expert has pm'd me with a suggestion that you may like to check out

here's the comment that he made:

All of those security certificate warnings seem very similar to what might be found by someone trying to use a malware attack tool. I wonder if the system is set up on a wireless A/P and if the warnings are only seen when accessing that router? It might be a good idea, if it is on a wireless A/P, to reset the router with new settings and encryption.

Ztruker, Thank you for your suggestions.
Re: "Try Firefox, see if the same problem occurs.
I attempted but stopped the download "Firefox" from "ezdownloader". Reason being I could not control unsolicited junk downloads and "free scans". I use both Google and Explorer browsers and receive similar (false) security alerts with either browser. Maybe I'll look for a safer F-F download and try it.

"Also, running System File Checker may be a good idea but you would need the Windows MC disc if there are any problem found."
I think there's a copy of "Windows MC" on my disk drive but I never had the disc.

paws: re: "It might be a good idea, if it is on a wireless A/P, to reset the router with new settings and encryption. "
I am on a NETGEAR N600 wireless router. Two hard wired XP pc's and one Windows 7 laptop interface with the Netgear but only one of the hardwired XP's have the false security warnings. With that, do you think it could still be a router issue?
Thank you, Jim
Download Firefox from here: Download Firefox in your language - though it's probably not worth the effort since you get the same error with Chrome.

How does it behave if you boot to Safe Mode with Networking? If better then something is starting at boot that is causing the problem.

Advanced startup options - XP
Advanced startup options - Vista
Advanced startup options - Windows 7

Use msconfig to determine what is causing the problem

These are good tutorials on using msconfig in XP, Vista or Windows 7:
How to use msconfig in Windows XP
How to use msconfig in Windows Vista
How to use msconfig in Windows 7 and Windows 8

Click on Start then Run, type msconfig and press Enter.
Click on the Startup tab (for Windows 8, the Startup tab has a link to open Task Manager/Startup tab. Use that.), record what is currently starting then click the Disable All button.
Reboot and see if it runs better.
If yes then use msconfig to enable several items at a time till you find the culprit.

If no, start msconfig and click on the Services tab.
Check the Hide All Microsoft Services box, record what is currently starting then click the Disable All button.
Again, do a regular boot, see if it runs normal.
If yes then use msconfig to enable services till you find the culprit.

Once you've found the culprit, uninstall it or find out how to eliminate it from your system. Simply disabling it in msconfig is a temporary fix at best.
Enable everything else you disabled.
A breakthrough!!!! I don't get the usual "false" security warnings when browsing with FireFox!!! Just prior to FF loading it prompted me about disabling certain startups: I disabled "AVG Safeguard Toolbar" (a program I've been unable to remove via normal process) and a second start up, called "Solid Savings" which I removed. Starting windows in Safe mode did not make false warnings go away. I did the msconfig instructions, but disabling startups and services did not change my PC's behavior. The "false" security warnings still appear. (with Google & IE) Thank you, Jim
Revo uninstaller does a slick job. I removed "AVG Safeguard Toolbar" and a couple other apps I had been unable to remove. However, my two browsers: IE and Chrome still give "likely false" security certificate warnings. FireFox browser does not. I want to remind that not all "https" type web sites I browse give the "false warning". Other banks in the area where I go to online don't have the problem.
sounds to me like a bad security certificate list somewhere in ie and chrome, some windows updates have been known to cause the problem.
so first thing i'd do is to run windows update a couple of times and make sure everything is up to date with no failed updates.

not sure if you've done this but then i'd clear the cache for both ie and chrome
http://www.wikihow.com/Clear-Your-Browser%27s-Cache
then reset both ie and chrome to defaults and see if the problem goes away.

http://support.microsoft.com/kb/923737

these links may help you solve the problem with those browsers if that didn't work :-

https://www.digicert.com/ssl-support/certif…usted-error.htm
https://www.sslshopper.com/ssl-certificate-…sted-error.html

as a last resort maybe i'd try un-installing both ie and chrome with revo and then re-installing them.

it might help if you visit a site that gives a warning in ie, make a note of all the bad certificate details then visit it again in firefox when no warning appears and compare the certificate details.

terry1966,
I appreciate your suggestions. I carried out cache reset for Google. I was thorough with updates.
I still have the "false security warning issues". I'm inclined not to uninstall/reinstall browsers, system s/w etc.
but I agree it's a good idea to chase the "certificate errors" that are at bottom of this annoying problem.

I can make the "false" warnings go away!
For the sake of troubleshooting I used IE to browse the WeatherBug site and made the "Security warning"
go away the next time I browse there by downloading the "certificate" to the "Authority" folder. Of course
just before launch, I get a Windows disclaimer as pictured. The windows disclaimer instruction looks reasonable;
it directs to go to "java.com" and verify digital thumbprint (see graphic). I had no luck trying to ok the digital thumbprint.
Ironically all my attempts to penetrate java support encountered the security warnings on every step.
My problem might be java. thanks Jim
