Please help, got stuck with a Trojan and a rootkit

[Jackiee]

I tried and I got the same window with the same error. The installation wizard asked me every time if I wanted to continue the setup without copying that file and I refused.

Shall I ignore the problem and continue without it? Or shall I manually copy and paste Blastcln.exe in the service pack files?

Could there be a problem with the permissions and settings of this file? as Avast has repeatedly reported it in the results report after complete scans.

[essexboy]

If you cancel does it progress to the next file ?

[Jackiee]

If I clicked "yes" (continue without copying the file), I think it would.

[essexboy]

OK give that a whirl whilst I do a little more checking

[Jackiee]

Fine I did. I hit "Run" and it says "no enough disk space for file expansion".
I've previously emptied more than 3 GB before I first run it and now it's only about 600 MB. Seems that it has been extracted every time I tried to run it to fix the problem, which is more than 5 times till now.

Is there a way to clear the space it filled for no use? if yes, what's the path and location?
Should I go for a system restore?

I do apologize for all the trouble I exhaust you with, Essexboy.

[essexboy]

Not a problem   Lets clear some space first

1.From the Start button menu, choose All Programs→Accessories→System Tools→Disk Cleanup.
2.When it opens check all options
3.Click OK

When done the window will close

Let me know if that clears enough space

[Jackiee]

After reboot, I got my disk space back, did the cleanup but not to the end and ran SP3.

I ignored blastcln copying and now it's installed. When it restarted the computer after the install, it asked about automatic updates and I turned them on.

So, is everything OK till now? Shall we check blastcln.exe and copy it manually?

[essexboy]

No blastcln is related to SP1 nad is no longer relevant to XP

How is the computer behaving now ?

[Jackiee]

very slow, maybe due to installing updates.

[essexboy]

OK lets now clear some rubbish and get the speed back   After this could you let me know if there is an improvement

Subject to no further problems   

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTL

• Under the Custom Scans/Fixes box at the bottom, paste in the following
  

  :Commands
  [resethosts]
  [emptytemp]
  [CLEARALLRESTOREPOINTS]
   [Reboot]

• Then click the Run Fix button at the top
  
• Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

• Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
  
• In the Run box, type in ComboFix /Uninstall
   (Notice the space between the "x" and "/")
  then click OK
  
  
  
  
• Follow the prompts on the screen
• A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.

Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

If you use on-line banking then as an added layer of protection install Trusteer Rapport

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

• Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?Keep safe  :wave:

[Jackiee]

Shall I do these first or finish installing updates?

If I chose custom installation, would I choose from these or install them all?

Shall I use "express installation" instead?

[essexboy]

Use express install to get the ones that are really needed

Once they have all installed then do the cleanup to remove all the rubbish

[Jackiee]

OK, thank you.  I will
