(Windows 7, 32-bit)
My computer was recently infeceted with a virus, which I (supposedly) successfully removed with RKill and MBAM.
I do not remember exactly what virus it was.
However, after that, I noticed my computer had slowed down a little, and my WiFi quality was greatly reduced.

Symptoms
The computer in general was slowed down.
Details for the WiFi problem is as such:
I have an unreliable wifi speed (Right-clicking on the network and clicking on Status, the "Speed" section is unstable).
It constantly changes from anywhere in the range of 18-48Mbps (It was previously constantly at 54Mbps)
Sent Bytes is higher than normal (5,000,000-12,000,000B)
Received Bytes is much higher than normal (10,000,000-25,000,000B)
Despite the high activity, pages do not load reliably: a page may need to be refreshed anywhere from 3-15 times before completely loading, Youtube videos do not load, etc.
---------------------------------------
I have already tried resetting my router, resetting my modem, connecting directly to the modem, restarting my computer, and re-scanning for infections. When I directly connect to the modem, I don't have any of these connection issues, so I am led to believe that this is some outstanding problem with my wireless adapter, or some wireless settings on my computer.
Another laptop on the same network does not have this problem.

This is my wireless adapter.
Realtek RTL8187B Wireless 802.11b/g 54Mbps USB 2.0

Thank you for your assistance!

I didn't save them that time, I'll scan again.

The log from the time I made the thread is not there... maybe because I restarted my laptop?
This is the earliest log that I could find.
