Viruses

Asked by: ralphwalkerdj

Inherited a computer with two viruses: w/32/ask_search.a.gen!Eldorado  and gzip bomb.  

I have F-Prot anti virus.  It says it finds these, but it does not remove them.

Are there dangerous?  How can I remove them?

You could check the support page for that virus maker or the Symantec support page to see if they have manual removal techniques.  A "better" solution would be to remove any pertinent data that's on the disk, if possible, and then wipe and reload Windows. Personally I like to know that I ma working with a PC that's as clean as possible before I start putting my important data on it.

As i think that files may be in use and the antivirus is unable to delete them
Autoruns for Windows v9.53
http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx

And check the autorun application at statrup through autorun utility and uncheck or delete the vague entry.
and restart ur pc and again run the scan.


or

try spybot
www.safer-networking.org

Malwarebytes' Anti-Malware

Write Rescue Cd and boot from it and scan ur system

Kaspersky Rescue CD

or
BitDefender Rescue CD

I forgot to mention that this is a server.  As such, much of the software above is not available.

Are these viruses dangerous?

 

by: jhyieslaPosted on 2009-08-22 at 08:07:56ID: 25158976

Any virus is a danger and if you have a server I'd definitely recommend wiping and starting over. Yeah, I know it's not the cool sexy answer that many people really hope for, but it's a for sure bet to solve the problem.

Once you get everything redone, make sure that you are using some good antivirus/malware program to protect your server from future issues.

I appreciate your frankness.  Are there any other ideas?

 

by: jhyieslaPosted on 2009-08-22 at 10:41:27ID: 25159532

Haven't found out much about gzip bomb, but the other one looks like "perhaps" it's some derivation of the mysebsearch tool bar.  I'd check in IE to see if you have that tool bar installed.  If so, I believe that you can remove it from the system with Add/Remove programs.

 

by: jhyieslaPosted on 2009-08-22 at 10:53:31ID: 25159578

Something you might also try to confirm that you have real threats is do download the scanner from www.prevx.com.  This is a product that I am testing in my environment and it will work on servers.  Now, the free download won't remove anything, but it would confirm the presence of these threats.

 

by: warturtlePosted on 2009-08-22 at 12:02:32ID: 25159810

Download MalwareBytes Anti-Malware as already suggested and do a scan with that as a start. It will work on Windows 2003 as well.

Following the above scan, reboot this server in safe mode and do a full scan of your server with F-Prot already installed. That should finish the infection.

Hope it helps.
