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.
