Major Internet security problems

I need help and, frankly, I'm not even sure where to ask. I have McAfee on my Compaq with Vista. It did work fine. My computer had to have the motherboard replaced and now the security system throws up a warning that says there is a certificate error. It shows up on sites like Bank of America, Gmail, Starbucks -- even McAfee. I also cannot get into the chat for McAfee support. After I download the program and try to run it, I get an error message. Can anyone offer any help? Thanks.

RE: Major Internet security problems

That sounds to me more of a Windows problem, namely the browser or system clock out of kilter.

What version of Internet Explorer do you have installed, regardless of whether or not you us it?

Did you reactivate Windows after the motherboard replacement? Also check that the system clock is accurate both time and timezone-wise.

You could try reinstalling McAfee, it may help.

1. Uninstall all McAfee programs through "Add or Remove Programs" in Windows "Control Panel".

2. Use the MCPR tool, see this article: How to remove supported McAfee consumer products using the McAfee Consumer Products Removal tool (MC... This will remove all McAfee remnants from your computer. (you must have Windows Vista, XP or 2000 SP4 to use this tool)

3. Launch Windows Explorer and delete all McAfee files in "Program Files" but especially in "C:\Document and Settings\<user>\Application Data" and "C:\Document and Settings\All Users\Application Data". You have to set Windows Explorer to show all hidden files and folders (Tools > Folder Options > View tab). Just delete the McAfee folders even if they are empty in all the "Application Data" folders. Can be more than one!
In Vista: C:\Program Files, C:\ProgramData and C:\Users\yourname\AppData\Roaming
If you can't find these files don't worry. It just means that MCPR has done its job.

4. Reboot and redownload/reinstall your McAfee products directly from your account at the McAfee web site.

If you are McAfee direct customer, go to https://home.mcafee.com/Secure/Protected/Login.aspx and log in to download your McAfee products.

RE: Major Internet security problems

I did nothing when I turned the computer back on. All my stuff seemed to be there. I'm using the latest Explorer. But this also happens when I try other browsers, such as Mozilla. And it happens only with some sites, not all.
Can you tell me how to activate Windows? And how do I check the clock to reset it if necessary?

RE: Major Internet security problems

It would help me to help you if I knew what version of Windows your are using and what service pack if any. Go to Start/Run and type in winver then click Enter. Type what it says. Alternatively right-click My Computer (XP), Computer (Vista) and go to Properties.

The latter will tell you also if Windows should be activated and/or you would be getting pop-ups warning you. The reason I proposed that was that when a major hardware change occurs Windows usually needs to be re-activated (which means basically that you need to re-register it with Microsoft). I can't tell you how as the pop-ups would guide you through that.

To check the computer time right-click the clock at the lower right-hand corner of your screen. Adjust the date and time if necessary.
