Solve : Help! Can't get rid of virus...?

Answer»

Hi, for some time now I have had a virus called "W32/Downloader.AOKZ" that has infected a file called "ldcore.dll" in system32 of Windows. I am alerted by my virus program but it cannot delete it. I have tried to manually delete it using Windows Explorer but an error message comes up when I try to do so, saying that it is used by another program. I am running a virus program called Freedom.

My problem is that I don't want to install another virus program, because last time I installed Norton and I had to reinstall my Windows because something happened. So, how do I get rid of this virus? Is it necassary to install another virus program? Do i uninstall the one I have now?stevengerrard ...... W32/Downloader.AOKZ ....looks like a trojan as opposed to a virus .....

so , If you are using XP ....... turn off your system restore , and then reboot into safe mode and run a full scan with your anti - virus scanner .........
See if it deletes it from there , if it won't post a hijackthis log .
Please explain what you mean by [highlight]I tried to remove it manually using Windows exporer .[/highlight]

dl65 What I mean is that I open My Computer, then the WINDOWS folder, then system32, and finally I try to delete the infected file by right-clicking and then delete.

So, I restart in safe mode and then run my anti-virus program?I would use the Ewido/AVG Online Scan but if you just want to delete the file then Google for Killbox.Fed, I used Killbox to try and delete the file and it STILL wouldn't delete. I also did that online AVG scan from the link you gave me and it didn't delete the trojan.


I have no clue as to how to get rid of this thing, does anyone KNOW how to?I feel for uDid the online scan detect the 'virus'?
What scanner do you use on this computer?
Did you explore ALL the deletion options in KillBox?Quote

I feel for u

Thank you, that helps.

The online scan detected the infection and supposedly removed it. When I restarted my computer my current virus program [highlight]Freedom[/highlight] (link below) found it again. http://www.freedom.net/viruscenter/onlineviruscheck.html

I did explore all options in KillBox and it still wouldn't delete.stevengerrard..... Would you please post a hijackthis log here for us to see ........ Get it at ..... http://www.majorgeeks.com/download3155.html d/L it and then run a scan and save the log file and post it here .


dl65 Ok, this is what I came up with...

I didn't find a great deal of info on Freedom AV at the security sites i frequent other than it uses the F-Prot engine...have you considered some of the other Free choices such as AVG and or Avast ? ?

However post a log as dl65 suggested. There's more than one way to skin a baddie...stevengerrard........ ok .......
Here's what I see from your log........
For some reason,you do not have SP2 installed and as far as I can see you dont have SP1 either ....... If this is the case , your machine is extremely vulnerable to nasty attacks.
Do you have all the other applicable windows updates installed ?
At the time your hijackthis scan was taken, there didn't appear to be any active anti - virus scanner running ......... I thought you had freedom installed or is it only active when you are online ?
Your firewall also seems to be non active as well.

Now then on to what must be fixed using hijackthis ........

put a check mark in the box in front of each of these entries and then click FIX MARKED

Now reboot your machine and post a new hijackthis log.
