Over the past 2 days, my internet speed has decreased significantly. I used to have no issues with my ping and internet speed. Now, youtube and online games have been rendered on playable. When using the command prompt to ping websites, the average ping is about 400 ms, ranging anywhere from 250 ms up to 700 ms. My download speed has been reduced from it's normal ~125 kb/sec to 10kb/ sec.
This slow internet speed has not just infected this computer, but all computers in my network. I have tried reseating my modem and my router, but neither of these methods worked.
I scanned my computer using both MSE and Malewarebytes, but neither turned up anything. However, upon examining the detected items history in MSE, I discovered that a Trojan horse, JS/Krypterade.A, had been detected on my PC 24 hours ago. There was no warning of this last night; no notifications popped up. This Trojan horse is supposed to be ransomware, but my PC has never been locked up and money has never been solicited from me via fake threats. Yet, task manager is showing multiple dllhost.exe *32 processes (up to 10) that are consistent with this virus. Network iControl is showing that this dllhost.exe is taking up around 100KBps of bandwith. I am beginning to suspect that I have a virus on this PC.
Due to the fact that downloads are excruciatingly slow and I don't have any other anti-virus software on my hands, is there anything else I can do before downloading new software? If it does come down to me being forced to download something, which programs should I get? Thanks in advance.
EDIT: I would like to add that Internet Explorer has stopped saving my information when I ask for websites to remember my log-in information. Furthermore, every time I restart Internet Explorer, file downloads are set to disable. Every single file I download has to be downloaded twice because after the first download, Internet Explorer states that the file was not downloaded (it works the second time though.)
