Here's the issue: Something is severely cutting into my bandwidth. I cannot stream video, streaming audio (Skype) is affected as well, and when trying to download a file it ultimately fails. Downloads seem to start at around 10-15K, climb to 30K or so and then rapidly drop off to 0K and fail. Page requests are slow too. Heavy websites, especially those utilizing Flash content stall. This has been consistent for about 3 weeks now, and has even crossed a reformat. I have Scanned with MBAM, MSE, Avira Anti-Vir and Sophos Anti Rootkit, and initially found some Malware, but these issues persisted beyond the cleaning. Currently running Agnitum Outpost, MBAM, MSE, Iobit Advanced System Care, and Trend Micro's RUBotted. I'm actively monitoring network activity, and while it's certainly not maxed out, there are a few unexplained "hits". A few important items:
1. I'm running wirelessly at 802.11g speeds right now. (out of necessity, not desire)
2. I'm using an Admin account. (which I will change immediately)
3. I'm active in the P2P community. (I know, I know)
Regarding item 1, My ISP rates my service plan at 8Mb, and historically I've had much better wireless speeds from the same location. I don't believe that this item alone can account for the behavior. Regarding Item 3, I can't really say that didn't know the risks, but hitherto, I've always been able to manage the fallout, even in the face of my lax security habits, as indicated by item 2. I guess technology is rapidly outstripping my ability to keep up. After researching and scanning for days, I'm fresh out of ideas, and I need some help. I can provide a Hijackthis log as a starting point.
