Help, computer infected

Viruses and worms
1

Okay, so warning I know very little about computers, so I’m going to sound like an idiot. Last week I was on youtube using internet explorer and the page started running very slowly and I began getting endless avast and malwarebytes pop-ups saying an infection was blocked and it was coming from several different sites, one of them was something along the lines of fffaa.com. I ran several scans with both and a boot time scan to no avail. To be honest, I’ve avoided windows updates for some time, which I realize now is a terrible idea, so I ran all of the windows updates, which took almost 5 hours because the computer was being severely bogged down by this infection and it gave me ie11. When I restarted everything seemed fine…for a day. The problem returned. It was then I noticed that the guest account was not having this problem, so I created a new profile, transferred anything I wanted from the old, and deleted the old profile. Everything appeared fine except for my computer getting pretty hot and running a bit slower than usual since the incident… until now, when I was again on youtube and I began experienced something similar, though not as many warning messages as the first one and listing a different site. I know I sound very ignorant about this, but I know my computer is infected with something and I desperately need help. Any advice would be greatly appreciated. I just received another warning popup, it says the source is C:\Windows\explorer.exe. I clicked on the “learn more” button and it says:

Okay, so following the directions on that link, here are the symptoms(whether all of them are related I do not know):

Speakers work, but do not show any sound system installed and cannot adjust the volume. Work normally 1/2 the time.
Computer slower than normal and running hot.
Continuous warning messages from both Avast and MBAM
(example of last popup:
Malicious Website Blocked:
IP: 88.214.193.212
Port: 57647

Process: C:\Windows\explorer.exe)

And here are the logs as instructed:

Hold on… I would’ve assumed Asyn would’ve contacted somebody.

He has but there are some qualified folk on vacation. Patience please.

Sorry it’s been some time, but here are the logs as requested. Thank you so much for your help!

10

And the others

11

Can anyone help? It’s been really bogging down my computer on and off.

12

Umm, I’m surprised Magna did not post back!

Hold on, I will PM Magna right now with your case!

Sorry about that.

Edit: I see the date difference is like 20 days, did not see that before. Regardless, he’s been PM’d about your case again. (Sit tight, it may be until tomorrow he answers back, it is very late for him)

Hello,

I probably somehow simply bypass your post …

I shall need a fresh FRST.txt and Addition.txt logfiles. Run FRST tool again, wait for update, press Scan button and post me the fresh logs.

It's been really bogging down my computer on and off.
Is your computer gets the random reboots?
14

Here are the logs. It’s not getting random reboots. The problem only seems to be occurring in 2 of 3 user profiles, “Elan” and “guest”. It appears to be trying to pull up ad sites, mbam blocks that from happening, but it still tries to so many times that it is making the computer heat up and slow down. Thanks for your help

15

The problem began occurring in my profile “Brian”, so I deleted it and created a new brian profile which stopped the problem for a short time. I started using the guest profile which wasn’t having the problem for several weeks, but then started having the issue as well as in the elan profile. I then tried Brian again and now that one isn’t having the problem currently.
