I see...
- PE_CORELINK.C-O, then is listed as a trojan, too...
Now, as for your HJT log, it's mostly clean, except for this questionable entry:
O17 - HKLM\System\CCS\Services\Tcpip\..\{7FE5BF47-CF53-4A96-BDE5-A8E1A087AF8B}: NameServer = 202.144.13.50,202.144.66.6
This particular IPs (202.144.13.50,202.144.66.6) are listed as "Asia Pacific Network Information Centre". If this is NOT your ISP provider, nor it doesn't ring a bell, it has to be fixed...
Here we go:
1. Print this post out, since you won't have an access to it at some point.
2. Download, and install Spybot (if you don't have it) from here:
http://www.safer-networking.org/en/download/index.html3. Close all windows, except for HJT.
4. Put a checkmark next to following HJT entries:
O17 - HKLM\System\CCS\Services\Tcpip\..\{7FE5BF47-CF53-4A96-BDE5-A8E1A087AF8B}: NameServer = 202.144.13.50,202.144.66.6
5. Click on "Fix It" button.
6. Restart your computer in Safe Mode (F8)
7. Run Spybot (click on updates, first), and fix whatever it asks you to fix.
8. Turn off System Restore.
9. Restart in Normal Mode.
10. Turn System Restore on.
11. Run HJT again, and post back its log back here.
