Cannot download anything but can use internet normally

[Broelski]

I cannot finish downloads in any internet explorer including "Internet Explorer", "Edge", and "Chrome". What happens is that I can start downloads, but after 3-4 seconds my downloads would just stall and show no error whatsoever, they would just completely stop.
Interestingly, I don't have this issue with FTP downloading (i.e. Torrent files). I can download large files with no interruptions at all.

Steps I have taken thus far:
1. Disabling Windows Defender & Avira
2. Running a full PC scan using Avira & Malwarebytes
3. Creating a new user and attempting to use the internet through that user
4. Deleting chrome (I can't reinstall it now lol)
5. Checked my internet through a different device, it worked with no problems.
6. Directly connected my tablet (I use my tablet to connect to the internet) via usb Ethernet, still same problem.
7. Used a different internet connection

All of these steps did not help. The issue started randomly yesterday. Google searching for an hour did not yield much help so I thought I'd seek your help here. Any assistance is highly appreciated. Thank you.

6. says it's not your PC, points to ISP/MODEM/ROUTER. Have you reboot modem/router yet, of course? are u using a proxy? are you using a custom DNS?

Hi,

Usually I see this problem with proxy, tcp/ip or cache poisoning

Goto http://www.bleepingcomputer.com/download in safe mode or from another computer and download /run

jrt/roguekiller/adwcleaner / minitoolbox or/and NetAdapter Repair All In One

do a cleanup with 3 first programs, reboot in safe mode and run minitoolbox or NetAdapter Repair All In One

good luck

Of course. Nope no proxy and no custom DNS. (P.S. Tested Google's DNS, didn't fix it)

@Dextermat: I couldn't find the first three programs. I've used all functions of NetAdapter though, didn't fix the situation.

Anymore advice is highly appreciated

I'd argue #5 and #7 pretty much rule out ISP/modem/router.

I've seen this happen once. Never totally pinned it down, but it felt like some kind of hijack/rootkit/whatever. I wiped the drive, re-installed the OS, apps, and data, and everything was OK.

The first 3 programs dextermat suggested are junkware removal tool, rogue killer and adwcleaner, all of which you can get from bleepingcomputer.com

JRT won't help with your problem, and I think adwcleaner does a better job than rogue killer, so out of the 3, I would suggest running adwcleaner, and also run combofix afterwards - also available at bleepingcomputer.com

@tman1: Thanks friend, Adwcleaner did the job quickly and efficiently. As it turns out, some left over files from chrome's cookies (or maybe downloads? I don't know) were responsible for this issue. I wish I could find the log to share the result with you so that others who may face the same problem might see the culprit but I accidently closed the log report and can't find it at the moment.

Again, much appreciated to you all for your help, and for you tman1 for your invaluable advice.
