First off I would like to say that I have used AVAST for 6 years now on several home built PC's and this is the first time I have ever been infected. I love avast and the existance of this forum makes me love it even more ...
Ok a few days ago I scanned my PC using the free avast version that I have always used. It showed over a 100 infections after a full system scan as well as full folders scan. I moved everything to chest as directed and then did a boot scan afterwards as directed but they where all still there. I scanned again with the same results. I also have had dozens off avast warnings windows poping up stateing that virus' has been blocked and moved to chest.

Use the Attachments and other options link in the Reply window to attach the logs.
That make it easier for all, you don't have to copy and paste into multiple posts and the malware removal specialist doesn't have to do the same to analyse it.

You're welcome, the idea of the tip is so that they can be attached to your posts if less than 200KB (or up to 4 files if less than 194KB)..

I downloaded Combofix and started the scan but it is telling me that Avast is still running...I confirmed that it is of as per your prior instructions and proceeded with the scan and now it is telling me that avast is still running but that combofix will proceed but "at my own risk"
Avast is turned off "permanently" under sheilds control and I confirmed that "enable self defense module" is unchecked..
Is it OK to proceed with Combofix???
-
If antivirus is disabled and Combofix still pop-up warning, then just ignore warning and run CF.
-
OK first thank you very very much Magna86 for your time....
Combofix is running now going on 25 minutes. I am on my wifes PC now before you ask :)
The stages have completed threw 50 and it now says
"system file is infected!! attempting to restore
c:\windows\system32\services.exe"
Witch is what the avast warning popups said under "process".
Just FYI
Thanks again!!
-
one other thing...my screensaver keeps starting up....will this cause any problems with combofix??
Its to late to turn it off but is it ok to wiggle the mouse from time to time...I know I shouldnt even touch it when the scan is running...
-
Hi,
When and if Combofix finishes its work you need to attach here C:\ Combofix.txt logreport so I could see what is done.
-
started preparing log report...
-
here is CF log report
-
and here is the Attached BlitzBlank report
-
also just now after I clicked on "post" for my last entry here for the log report...A different avast window poped up telling me that an un identified program was trying to access my pc.
it was the same c:\windows\system32\services.exe
It asked me what to do and I clicked on send to chest
FYI....I started Avast back up within minutes of CF restarting my comp and it was done preparing Log report and before I went online to post

Thank you Magna86 for all of your help with this...I have decided to do a fresh install of windows. I simply have run out of time.. I am leaving for a couple of weeks for work and my son and daughter both are going to need to use my PC for school... and since I really dont have anything on my pc that isnt backed up I figured this would be the best thing to do.
I have removed the PC from the internet and deleted a ton of files freeing up disk space, I am now in the process of defraging and then will use CCleaner to wipe the free space. Then re-install...
However...
I am still considering just partitioning the drive and installing WinVista 32 bit on the new partition then wiping the current 64 bit portion of the drive. I own a Full Retail version of Vista ultimate (non OEM).
I feel that this would insure that any remnants of infection would be cleared???
Thoughts??
Once again thank you for your help.

My opinion is that you should hold it a little more and I would have removed every possible trace of infection.
Above CFScript that I wrote was written just for your machine and your rootkit versions. It would eliminate malware.
I am also of the opinion that the re-installation of Windows, sometimes is the best solution.
Though the malware has been identified and can be killed, due to its rootkit & backdoor functionality...many experts in the security community believe that once infected with this type of malware, the best course of action would be to do a reformat and reinstallation of the operating system (OS), but this action is not necessarily.
I am still considering just partitioning the drive and installing WinVista 32 bit on the new partition then wiping the current 64 bit portion of the drive.
I own a Full Retail version of Vista ultimate (non OEM).
Why to install 32-bit (x86) Windows when you can install the x64bit version?
You have 4.00 Gb of Ram. x32bit Windows sees only 3.25Gb of ram ( in very rare cases 3.70GB )
Once again thank you for your help.
Hey, no problem ;)
