HIJACKED! Won't run anti-virus! HELP! HJT Log!

I think some virus or trojan is on my system trying to dial out. Checked the event log and found this: Since 1/2/05 there have been 2,322 events logged...mostly errors and a few warnings. Most are a "DCOM" error #10003, there is an "RSVP" warning #10047, a "Schedule" error #7901, a lot of "Service Control Mgr" errors # 7001 & 7026, several "event log" warnings with various numbers, "Srv" error #2012, and hundreds of MrxSmb errors #3034. All those red error dots are scarry... but the worst part is
I am having problems...major ones actually! Over the weekend my AVG found 4 viruses and Panda scan found 6. Have found another 2 since then! Thought I had removed them... I can't add/remove any program on this machine. It now tells me that (whatever) program was installed using admin rights and won't let me remove anything. Access DENIED! I have tried to run a trend Micro Housecalls scan...nope! Same with Panda Scan. Same with the one you suggested... the files won't download to scan anything. I get error messages and the program won't work. SOmEthINg has a grip on this system and doesn't want to let go. I should probably do a clean install but...DON'T really want to do that as time is short and my knowledge limited at best. I am posting a HiJack log. Does it appear to have problems there?
Thanks!
PS... when I open HiJAck there is an error in red across the top that reads ""01 host file redirection". The scan posts 1 result in the box and then I get the following pop-up error: "For some reason your system denied write access. If any HiJacked domains are in this file HiJack This may NOT be able to fix this. If that happens you need to edit the file yourself. To do this click start, run and type 'notepad C:\WINNT\System32\Drivers\etc\hosts' and press Enter. Find the line(s) "HiJackThis reports" and delete them. Save the file as "Hosts" (with quotes), and reboot."
Then it goes ahead and posts the log??? Something doesn't look right there. This is a new problem as well. Here is log.

Sorry,
Maybe I wasn't specific enough. I CAN'T do any of that. Most of the programs/upgrades tried simply give me an error message that they can't load the ActiveX files??? The others, like Spyware Doctor setup downloaded but tells me access is denied when I attempt to open and install/run it! Went't to try and log in as admin and getting access denied there too! I don't know what to do next! I can't run any of my spy/antivirus software and can't download more!!!

 

try this online scanner
http://uk.trendmicro-europe.com/consumer/products/housecall_pre.php

it uses java isntead of activex.
