RTC is reset, Clock is wrong, Won't connect to Internet

Specs: Windows 7 Pro 64 bit, 8 GB RAM
Hey - this is my mother's computer, which suddenly is being very strange.

It's a dell desktop running Windows 7 Home.

Everything was fine last night, but when we got up this morning the screen said "RTC is reset, BIOS Setup default has been loaded. Strike the F1 key to continue, F2 to run the setup utility."

I had no idea what to do, so I hit F2, thinking it would run the startup repair. The internet icon and antivirus were missing at startup, so I restarted.

When I tried to search what was wrong, Firefox claimed that the connection was not secure. I can't get anything to work with the internet, though it claims to be connected.

I tried running system restore, but it didn't work. Claimed the antivirus was holding a file it needed, and to disable the antivirus and try again. It was when I did that that I noticed that it claimed today to be February 1, 2013, and 1:00 PM (It's roughly 11:00 AM right now.)

I'm running system restore again. What else should I try? I've never seen something like this happen before and Google is not helping.

EDIT: The first thing I saw after the restore was AVG reporting a threat to C:\Windows\SysWOW64\WTClient.exe. Now I'm fairly sure that's a file for the net, but I told it to take care of it. It's currently restarting.

Restart complete, and it claimed to restore to 7/3/14, yet the clock still says 2/1/13 and firefox still claims no secure connection. Help?

You probably need to change out the CMOS battery on the motherboard.

Be sure to unplug the computer before entering the case. After installing a fresh CMOS battery you will need to enter the BIOS (setup) and reset the values. The date and time and possibly the boot order.

I...have no idea how to do that, honestly. The computer was only purchased this last December, so soon with a battery? Will that help with the internet?

EDIT: Research has shown that yes, fixing the clock fixes the internet. No clue why this happened, but looks like that helps at least.

EDIT The Second: Windows Update claimed it needed to update something, so I did - and AVG claimed a threat in "Self Updater". I don't know.

If the computer is that new, it should still be under Warranty. I'd contact Customer Service for whomever manufactured it.

The battery typically looks like a large watch battery; flat, disk shaped and usually quite shiny... About the size of a Canadian/US quarter. Usually they clip in in and so are "relatively" easily removed...

Ensure you install the replacement the correct way round...

If you were to post the model of the Dell desktop pholks here can likely guide you further in locating and removing the battery.

Equally if you have the manual around it may also include that same information?

Have to observe that for "new" computer that's a very short life for the cmos battery; or is this actually a used Dell? My own experience is that cmos batteries usually quite a while a year or three at least)?

And these two links may help...


- this second link is a Youtube video showing how to do it.

They did replace the motherboard before, but indicated we were near the end of the warranty. (Things about how it was bought and then kept in the box for awhile.) I'm a bit worried right now about AVG finding these threats - and if my tablet will still work since I'm pretty sure it's one of the things it claimed was a threat - but I can't find them in the 'virus vault'. It's all very confusing and upsetting here, and I apologize if I seem utterly hopeless but we have no idea what it's doing.

Just saw the post about the battery - I'm not 100% sure anymore ow new the motherboard is. It ended up being the monitor (separate) that was the problem at the time, but still. They did replace the motherboard, so the battery was probably replaced too.

I'll try and get the model info. I'm currently debating undoing the system restore, but I doubt it'll change anything.

AVG claimed a problem with the WTClient, and I can't find the undo for that and my tablet won't work. So I'm trying another restore - it won't undo the last restore, but it will restore to about a week ago.

Yet another update (sorry, just trying to keep things up to date) - Did the restore. WTClient is back, clock is still correct. AVG claimed it was a threat, I said it wasn't. Tablet's working again.

Often when a pest (virus etc.) is removed from the system it won't appear in the "vault" as a result.

If you opted to quarantine a suspect item then that will *normally" be shown n the quarantine folder for the anti-virus utility.

Can't see why your tablet won't continue to work... Some anti-vurus utilities will raise a false "flag"/alert for all manner of reasons... Often if there are two or more anti-vrus utilities installed at the same time; but not always.

You could also go on-line to Trend and run their freebie Housecall anti-virus (on-line) scan. It will take a while to run so time for tea/coffee 'n cake.cookies...


But I'd first consider replacing the cmos battery; as it's a relatively simple operation overall. But be sure to remove the power cord from the system - so no power is even attached... With modern computers - if the power cord is attached and the mains outlet is switched on... even with the computer itself switched off... there are still volts running around inside the system. So one "must" remove the power cord fully; and if a laptop then also the battery to ensure it is fully powered down

The tablet refused to work since AVG removed the WTClient.exe - which is the thing that makes it work. Now AVG is claiming that WuSetupV.exe is suspicious - you know, part of windows update. It's the only antivirus on there, and there hasn't been a virus for a long time, so...I'm starting to suspect it's messing with me. I added both to the exceptions list.

I'll look into the battery, though, and try to do either malwarebytes or the housecall scan later.

Does this mean everything is working OK - apart from AVG saying there is a threat?

So far, apart from AVG having claimed that two files I know are fine were threats (I told it to make exceptions for them) everything seems to be working okay. I had to restore to get said files to work again, so I have to do some updating, which is a little nerve wracking, but yes, so far so good.

I'd be inclined to run MalwareBytes on it as there is some suspicion that you have been compromised by a virus or similar:
[Use green download button top right]

MWB is good at finding and fixing Malware that virus checkers miss. If it finds anything please copy-paste the log on here so that we can see what it found.

Always pop back and let us know the outcome - thanks

If the CMOS battery seems to be rather new, then I suggest you simply reset the date and time in the SETUP screens. Be sure to save the changes when exiting. If you do that and you see the date and time are wrong after a complete shutdown without any power to the computer, then replace the CMOS battery. They only cost 3 or 4 dollars. As methioned above, the battery has two sides to it. Be sure you pay attention to which side faces up BEFORE removing the old battery.

This might help explain your observation in # 2 that 'fixing the clock fixes the internet':

Othehill, I reset the clock just by clicking on it while it was on and resetting it, so far it has seemed to be all right. I'll see what happens when we turn it back on.

Derek, that sounds like a good idea. I'll run that after we've turned it back on.

Daveincaps, I figured it was something to do with the certificates for the websites. Thanks for the links though.

Since it's a desktop, and we're supposed to have a bunch of storms today, it's off right now and unplugged, and likely to be both for the rest of the day. I'll try to come back with a follow up after it's been started back up and I can check things.

You may still have the ESET tool we used on your comp, it is certainly very good tool to keep, just run & update. It is part of my toolkit on a thumb drive.

Run ESET Online Scanner, Copy and Paste the contents of the log in your reply please. This scan may take a very long while, so please be patient. Maybe start it before going to work or bed.
You may have to download ESET from a good computer, put it on a flash/thumb/pen drive & run it from there, if your comp is unbootable, or won't let you download.
Create a ESET SysRescue CD or USB drive
How do I use my ESET SysRescue CD or USB flash drive to scan and clean my system?
Configure ESET this way & disable your AV.
How to Temporarily Disable your Anti-virus
Which web browsers are compatible with ESET Online Scanner?
Online Scanner not working
Why Would I Ever Need an Online Virus Scanner? I already have an antivirus program installed, isn't that enough?
Once onto a machine, malware can disable antivirus programs, prevent antimalware programs from downloading updates, or prevent a user from running antivirus scans or installing new antivirus software or malware removal tools. At this point even though you are aware the computer is infected, removal is very difficult.
5: Why does the ESET Online Scanner run slowly on my computer?
If you have other antivirus, antispyware or anti-malware programs running on your computer, they may intercept the scan being performed by the ESET Online Scanner and hinder performance. You may wish to disable the real-time protection components of your other security software before running the ESET Online Scanner. Remember to turn them back on after you are finished.
17: How can I view the log file from ESET Online Scanner?
The ESET Online Scanner saves a log file after running, which can be examined or sent in to ESET for further analysis. The path to the log file is "C:\Program Files\EsetOnlineScanner\log.txt". You can view this file by navigating to the directory and double-clicking on it in Windows Explorer, or by copying and pasting the path specification above (including the quotation marks) into the Start ? Run dialog box from the Start Menu on the Desktop.
If no threats are found, you will simply see an information window that no threats were found.

Mum turned the computer on this morning. Clock's still fine, and everything seems to be running well. I ran a malwarebytes scan and it came up clean. So...looks like we had a pretty crazy system hiccup, but I guess it's all okay now. Thanks for the help everyone.
