Removing Win32/Bagle.HE worm

Paul15 Replies

Here is another virus that seems to be spreading lately.   From the looks of it, it sees to be another email worm.  Here is what eset says:

Aliases

Email-Worm.Win32.Bagle.gt (Kaspersky), W32/Bagle.gen (McAfee), Trojan.Tooso!gen (Symantec)

[ad#ad2-right]Win32/Bagle.HE is a worm that spreads via e-mail. The size of its executable is 40565 B .

When executed the worm copies itself in the following locations:

  • Documents and Settings\All Users\Application Data\hidn\
    hldrrr.exe

  • Documents and Settings\All Users\Application Data\hidn\
    hidn2.exe

In order to be executed on every system start, the worm sets the following Registry entry:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\drv_st_key

[ad#ad2-left]It seems to have a manual removal process, Unless you pay for the other software but according to the 411 on PC Security:

Win32/Bagle.HE worm is a “threat” that appears in security scans by fake antispyware WinDefender 2008.

The danger of Win32/Bagle.HE worm is supposed to scare you into wasting $49.95 on WinDefender 2008.

Unless you like getting ripped off, don’t download the software the Win32/Bagle.HE worm popup links to. You’re not really infected with Win32/Bagle.HE worm — you’re infected with scamware that you need to remove.

I’ll show you how to get rid of Win32/Bagle.HE worm and WinDefender 2008, for free.

[via 411 on PC Security]

According to this site you can remove it by doing some steps.  I think Kaspersky has an easier way to remove it and it looks like most anti-virus software will remove this.   You need to remember that only you can prevent this from the future.   You should also update your windows update and make sure your system is up to date.

Figuring out the Email-Worm Win32.Zafi.b

Paul

This is another just I just saw on the web and wanted to talk about what this little Worm does and what it’s known Aliases:

Email-Worm.Win32.Zafi.b (Kaspersky Lab) is also known as: I-Worm.Zafi.b (Kaspersky Lab), W32/Zafi.b@MM (McAfee), W32.Erkez.B@mm (Symantec), Win32.Hazafi.30720 (Doctor Web), W32/Zafi-B (Sophos), Win32/Zafi.B@mm (RAV), PE_ZAFI.B (Trend Micro), Worm/Zafi.B (H+BEDV), W32/Zafi.B@mm (FRISK), Win32:Zafi-B (ALWIL), I-Worm/Zafi.B (Grisoft), Win32.Zafi.B@mm (SOFTWIN), Worm.Zafi.B (ClamAV), W32/Zafi.B.worm (Panda), Win32/Zafi.B (Eset)

[ad#ad2-left]This worm spreads via the Internet as an attachment to infected messages, and also via local and file-sharing networks.
It is written in Assembler, and packed using FSG. It is 12800 bytes in packed form, and 33292 in unpacked form.

This Worm seems to be running through email and file sharing sites, One thing it tries to do is stop the process and deletes:
fvprotect.exe
winlogon.exe
jammer2nd.exe
services.exe

It attempts to detect antivirus program files on the computer and overwrite them with a copy of itself.

[ad#ad2-right]It also attempts to conduct DoS attacks on the following sites:

www.2f.hu
www.parlament.hu
www.virusbuster.hu
www.virushirado.hu

This seems to be a very big virus and can be removed with the use of Kapersky Virus removal tool for free for this type of virus. In order to prevent this virus in the future the user has to remember about not getting opening unknown documents or emails and not running any unkown program from an unknown file sharing.   Also remember you need to have an anti-virus  and also a firewall to protect yourself in the future.

Inside understanding of win32.netsky.q

Paul

Netsky.Q is a worm that spreads through e-mail. It is distributed as a 28,008 byte Win32 executable, compressed with PEtite, which drops a 23,040 byte DLL file. It also distributes itself inside ZIP archives.

I saw this on on the net and through we should talk about and let people know how you could get that the worm off your computer. It seems to be a self-replicating worm, it will continue to send out fake messages to people with the subject lines Like:
[ad#ad2-left]

  • Delivery Error

  • Delivery Failure

  • Delivery

  • Mail Delivery failure

  • Mail Delivery System

  • Mail System

  • Delivery

  • Delivered Message

  • Error

  • Status

  • Failure

  • Failed

  • Unknown Exception

  • Delivery Failed

  • Deliver Mail

  • Server Error

  • Delivery Bot

And with each message there is the reciepts email address at the end.  This worm seems to be spreading like wildfire today.   It is because people have not install

Microsoft Security Bulletin (MS01-020)

[ad#ad2-right]Now how do you get rid of it.  It seems that most of Anti-Virus software would get it done.  All you would need to do is scan for this virus with the latest updated virus databases and will go away.   According E-Trust Anti-Virus they say they can remove it.   This is a really old virus, according to my sources this was first seen in 2004.   In order to prevent this in the future I’d suggest installing a free anti-virus and using it.    This is one smart little worm according to CA IT.

If you have quite a few Desktops in your Office and want to update all of them to the newest patch all in one swoop, I’d suggest downloading Clone of Autopatcher and making an ISO image so you can go around to each computer and install the patches quickly and easily.  Prevent yourself from getting that virus and some others in the future.   This is a friendly tip for all those hard working IT workers.
