Paranoia Man

I tried to download Panda TotalScan, but it immediately came up with the message: "Sorry, loading is incomplete due to an error. Please try again. Error 1002." I tried to lookup solutions to this problem but I could not find any.

Wow, thanks for the heads-up! I downloaded and ran ComboFix and got the following log: ComboFix 07-12-02.7 - Zavala 2007-12-05 16:36:03.1 - NTFSx86 Microsoft® Windows Vista™ Home Premium 6.0.6000.0.1252.1.1033.18.2006 [GMT -5:00] Running from: C:\Users\Steven\Desktop\ComboFix.exe .

I did what you said and the scan came up with: Deckard's System Scanner v20071014.68 Run by Zavala on 2007-12-02 14:09:53 Computer is in Normal Mode. -------------------------------------------------------------------------------- -- Last 5 Restore Point(s) -- 33: 2007-11-30 10:44:49 UTC - RP98 - Windows Update 32: 2007-11-28 19:57:57 UTC - RP97 - Windows Update 31: 2007-11-21 12:56:02 UTC - RP96 - Windows Update 30: 2007-11-20 03:18:10 UTC - RP95 - Windows Defender Checkpoint 29: 2007-11-18 19:11:23 UTC - RP93 - Installed QuickTime -- First Restore Point -- 1: 2007-10-07 23:29:05 UTC - RP63

My internet connection keeps breaking about every 30 seconds when I try to download files or video, yet the connection seems fine when the computer is off or when I am not currently downloading anything. I have tried running Trend Micro Antivirus and Windows Defender but they don't find anything and I can't figure out what is wrong. I think it might be messing up because of a hole left over after I removed a trojan downloader with Windows Defender. I decided to download HijackThis and see if it would help. Please give any help you can. Here is my logfile: Logfile of Trend Micro HijackThis v2
