Pc Infected With Rootkit? / Fresh Install Doesn't Help

I am having major issues with my PC. I am experiencing all types of apps hanging, can't click on programs via the start8 menu, even once got locked out of logging into my account because there wasn't any text box for me to type my password into! I have paid versions of both Malwarebytes and Avast Internet Security but neither of them have detected any actual viruses. All the sluggishness and constant rebooting was tiring and I decided to wipe the drive (or so I thought) and reinstall Windows via the partition. Everything seemed fine, but I did notice some software that comes bundled with the PC wasn't reinstalled (very curious!) and the app hangups and not being able to click on the menu continued. And I barely installed any programs. Just a few essentials like Malwarebytes, Avast, Stardocks: Start8, Fences, and ModernMix. Again still the problem continues. I started reading up about how viruses can worm their way into the boot of the system and avoid detection and reinstalls of the OS. I was able to grab a copy of GMER and run that in safe mode and it popped up some curious results. Unfortunately, I am at a loss as what to do about them. I also want to mention that whenever I go into safe mode with networking; the networking part usually does not work. At the time of writing this the LAN connection does seem to be working though. But Malwarebytes and Avast can't do real-time protection and I'm not sure if that's due to being in safe mode or something interfering with them. Another thing I noticed before I did the fresh install of Windows was that whenever I was connected to wifi (I have both LAN and wifi on my PC) the applications would act twice as wonky and stop responding most of the time. If I turned off the wifi (via the Amplifi app on my phone; since disabling wifi via the menu on the PC didn't actually disconnect it) it seemed to calm down a bit. That was leading me to believe I had some sort of virus or whatever attacking my wifi connection (yes, it's password protected). But then the fresh install and not turning on wifi didn't yield any better results. So I'm here turning to you as I feel completely overwhelmed and at a loss at what to do with my precious PC. I would like to get back to gaming asap, but I feel things are going to be very grim for quite some time.

I've attached two different logfiles from GMER.

I would recommend running are malware guide and posting the logs on the main Specialist.

Nothing seems out of the ordinary to me in them log's.

Post your logs here https://forums.majorgeeks.com/forums/malware-help-mg-a-specialist-will-reply.35/

Are you aware of this?

Yet another reason i don't have anti virus software installed.I only use them if my system starts acting funny.

I have what is called a Flash scan i boot from my USB drive VM and run all the software in there.This way it stays off my computer.And does not slow things down.

 

No, I was not aware of that. But my problem wasn't not being able to access websites. I didn't have any issues browsing the web. My problem is I can't open most of my programs. Everything tends to hang and say "not responding." And my start8 taskbar (I don't use that native Windows 8 start menu..I prefer the desktop and taskbar) wouldn't let me click on the programs opened in the taskbar. Right-clicking on a program on the taskbar wouldn't open a menu, it would just show the busy cursor and do nothing else. Opening a program from the programs list wouldn't open anything. Acts as if I didn't click on the program at all. It's hard to explain. I wish I could explain it better than this! I'm not able to open things like regedit and taskmgr. Going to RUN > regedit or taskmgr doesn't open anything. It acts as if I didn't the command at all. At the moment I don't even have Avast installed because it wasn't working so I uninstalled it. I have the free version of AVG antivirus installed but protection is off on that.

Where do I get this flash scan that I can boot?

Guess I'll go do that scan you suggested. But if it's some hidden rootkit. I doubt a simple adware scan is going to reveal anything.

 

A USB scan is you have to make your own.

It's a version of windows installed onto a USB flash drive.You will have to setup anti virus tools onto that your self.Then you will need to scan your main C: drive from the USB flash drive.

You can pick what ever windows you want to run.I prefer windows 7.Sorry if i was not clear.

Some times i call it a hot scan or flash scan.Be cause i have it setup to load into windows off of flash drive and auto scan right away.

You would have to make sure it's a USB 3.0 Flash drive for a quicker response time.

 

If you suspect a rootkit, a Kaspersky Rescue Disk bootable CD is a decent direction.

Either that, or wiping the MBR with a copy of Darik's Boot and Nuke. A Windows format ordinarily does not delete the Master Boot Record.
