hello everyone.

For some time now my connection speed is becoming slower and slower.
I always used AVG free 9.0 as my virusscanner and installed it on every PC on my homenetwork but yesterday I downloaded and installed Spyware Doctor and it found 12(!) trojans in the first full scan and 2 more in a scan following the first one. There where some w32 and Generic (if i remember correctly) trojans which seemed to freak out AVG and Spyware Doctor quiet a bit.

Since Spyware Doctor found 2 new trojans in the second virusscan I figured out i might have a backdoor?

Over the past half year the internet download speed dropped twice with 50KB/s. From 150KB/S to 50KB/s. I always thought this was because of the provider but since i found that much trojans yesterday I want to rule out that the slowing down of the internet is due to trojans/virusses/worms/spam etc.

The only thing I haven't tried yet to find any threats is HijackThis because i can't figure the logs out smile.gif
(list of programs i have tried; Unhackme, a-squared, AVG, spyware S&D, Spyware Doctor and some more of which i don't know the names anymore)

Could someone please take a look on the log HijackThis came up with and see if something isn't right? and i apologize for my poor English smile.gif

in an other topic i read something about combofix and Rkill
i downloaded and ran them both (turned of the virusscanners), Rkill gave me a clean log, combofix deleted a few files and gave me the attached log.
After combofix stopped i turned Spyware Doctor on again and did an intelli-scan and it found a trojan downloader (murlo) and a trojan (trojan.generic).
This isn't right, right?
