Win32:Sirefef-BTT(Trj) Virus on my really old pc…is there any hope?!!

Hi all

I’m also having a similar problem to Vulpicurious. I fear I’ve actually made things worse by my lack of knowledge and my general impatience! I’m currently running ComboFix so I’ll let you know how it turns out. My PC is absolutely ancient - I believe around 8 years old actually but it’s been a great system and despite my using and abusing it with multiple downloads it’s continued to serve me well - until now. I fear my old pal will be heading for the bin. Do you think there’s any hope for me to fix it?!!

I do have a laptop which I’m currently using to type this so it’s not all bad. I’m just stubborn and don’t want to bin my old faithful!

Any thoughts?!!

Hi,

I'm currently running ComboFix
Hm...bad chose to run CF unsupervised ... Post here CF log.

THEN

Please download Farbar Recovery Scan Tool by Farbar and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

[*]Double-click to run it. When the tool opens click Yes to disclaimer.
[*]Under Optional Scan ensure “List BCD” and “Driver MD5” are ticked.
[*]Press Scan button.
[*]It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
[*]The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

THEN…

Please download GMER, the AntiRootKit tool from the link below and save it to your Desktop:

Gmer download link
Note: file will be random named

Double-clicking to run GMER.

[*]Wait for initial scan to finish - if there is any query, click No;
[*]Click [ Scan ] button and wait until the full scan is complete;
[*]Click [ Save … ] button - save the report to the Desktop (named ARK );

Please attach here Gmer’s (ARK.txt) logreports.

Thanks. I’ve attached the ComboFix Log.

Please find attached the Farbar recovery scan logs:-

I really appreciate your help and support.

Here is the GMER scan log…it’s too big so I’ve split it into 2 - hope that’s ok

[list]Hi,
Mistakes that are made by running ComboFix:

CF has not been run from Desktop:

Running from: J:\ComboFix.exe
You have been just create shortcut by mistake or or intentional.
C:\Documents and Settings\Leonna\Desktop\Shortcut to ComboFix.exe.lnk
Drive c: () (Fixed) (Total:228.11 GB) (Free:58.13 GB) NTFS ==>[Drive with boot components (Windows XP)] Drive j: (KINGSTON) (Removable) (Total:0.48 GB) (Free:0.47 GB) FAT
===============================

Your system is in a disastrous state. You need to stay with me to the end untill we fix your computer.

Multiple Antivirus Programs

You are running more than 1 Antivirus program!

Running - more than one - antivirus program is not recommended because:
[*]They can conflict with each other.
[*]Report the other antivirus software as malicious.
[*]Antivirus programs use an enormous amount of computer’s resources… actively scanning your computer.
[*]Can cause your computer to become unstable…run slowly and even, in rare cases, BSOD crash…etc
I strongly suggest you uninstall one of them. Which one, is your decision.

=> Wisit this website for downloading AppRemover tool:
http://www.appremover.com/

Follow video from the site, run this tool, and remove any found remainder of previsu installed AntiVirus. Do not uninstall avast.

I recommended to use MCShield if you will.
You may download MCShield from one of the following links:

MyCity - Official download link
Softpedija - Mirror download link

It will prevent infection by computer via USB flash drive, mobile phone or any other memory card.
And not only will prevent infection, but it will immediately clean flash drive, memory card or external HDD.

Thanks Magna86.

Followed your instructions. GMER.exe is still present on my desktop, but everything else looks as if it’s gone. I’m now having issues with Google as well - whenever I do a google search I just keep getting tab recovered then it fails to display any search results. It only seems to be google - if I type in an address it comes up fine. Have installed MCShield as recommended.

Thank you for your patience - you’ve been amazing.
