OK, first off, my specs:

-Windows 7 Home Premium, SP1, 64 Bit

-16 GB DDR3 RAM

-Intel Core i7-3720QM, 2.60 GHz

-Samsung EVO 840 500GB SSD

-nVidia GTX 680M discrete graphics

If there's anything important missing here, please let me know.

 

Okay, on to my problem:

I have no earthly idea what's going on. The symptoms are as follows:

-Windows Update can't install any updates to the OS, security updates, anything like that. It CAN and does install driver updates, such as new drivers for my graphics card or other hardware, but the OS can't update.

-Every time I restart the computer, the date and time are changed, usually by one hour, sometimes more. Additionally, any changes I've made to the system disappear.

-ANTIVIRUS KEEPS DISAPPEARING. This is a HUGE red flag, it makes me suspect that I've got some sort of incredibly nasty malicious program on my computer. At first I had Avast! installed, then one day I noticed that disappeared (this led me to take note of the other funky stuff going on, too). I tried starting up Microsoft Security Essentials, only to find that the service for MSE wasn't installed anymore on my computer. So, I uninstalled and reinstalled MSE. Then, I restarted again, and voila, the service was gone again. Something appears to be actively deleting antivirus on my computer. This seems very, very bad.

-I managed to get Malwarebytes (the free version) installed on my computer and it doesn't disappear upon restart. It doesn't get deleted, but every time I run the scan it finds a few PUPs, but no malware. It removes said PUPs, but when the computer restarts they're back again.

-I don't know if it's related, but I've been having issues with Steam installing games, as well. Much like my updates, they either don't install or don't download, period.

-My computer is running way slow and rather hot. This is a decently beefy PC for a notebook, but you wouldn't know it by its performance. On desktop, sometimes it'll grind to a standstill over nothing.

-Sometimes, Windows won't even start up, giving the "unmountable boot volume" error. I don't have my Windows 7 install disk with me, but I have made a Win7 recovery disk, which has successfully run startup repair and fixed the error. This has happened more than once, though.

-For whatever reason, I am unable to make system restore points.

-When I try opening the command line and run SFC /SCANNOW, it tells me there's a system repair ongoing and I have to restart the computer to finish it. It says this every time. (UPDATE: it just ran for the first time, it said "Windows Resource Protection did not find ayn integrity violations.")

I'll update if I remember any more symptoms.

 

I have tried the following:

-restart the computer (this only showed me that I had a bigger problem than I thought)

-command like SFC /SCANNOW (see above)

-run several different anti-malware scans (in safe mode): Spybot search and destroy 2.4, Trend Micro HouseCall, Malwarebytes, even Windows bleep Defender. Nothing came up.

-run the Kaspersky Recovery Disk. It found nothing.

-run the f-secure recovery disk. It wouldn't work, as I don't have a wired internet connection (I'm on a semester abroad in Spain), and there's apparently no way to get it to update its definitions without one. Yes, I tried making a bootable USB drive, that didn't work either, it still needs a wired internet connection.

-use CCleaner to clean up the registry.

 

Any other suggestions, anyone have any idea what's going on here? I can provide more information if necessary! I just really need help here.. Thank you in advance.

 

Edit: I posted here because it seems like it may be a problem with my operating system installation, though I'm not sure. Please let me know if there's a better forum to post in.

Your issue will require further investigation and a more comprehensive look at your system. Many of the scanning tools we use in this forum are not capable of detecting (removing) all malware variants so more advanced tools are needed to investigate. Before that can be done you will need to create and post a FRST log for further investigation.

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.
When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. Explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can close this one.

Quietman7, thank you for your advice. I'll do that sometime this weekend right now and report back, linking to the new topic so this one can close.

 

Edit: I've just made the logs. I've posted my symptoms, copy/pasted from my post here, and the FRST and Addition log files as attachments. The new thread can be found here.

 

Go ahead and close this thread!

You're welcome.

Now that your new topic is posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Response Team member...nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the information or any log(s) you already posted. Further, any modifications you make on your own may cause confusion for the member assisting you and could complicate the malware removal process or make things worst which would extend the time it takes to clean your computer.

From this point on the Malware Response Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take several days to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers but your topic will be reviewed and answered as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Response Team member is already assisting you and not open the thread to respond.

I advise checking your new topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, please follow Step One and CLICK the link so it will report your topic to the team members.

To avoid confusion, I am closing this topic.

Good luck.
