If you're unable to browse to Antivirus or Microsoft sites (MyDoom.B side effect), use the following procedure

by Marianna Schmudlach / January 30, 2004 2:40 PM PST

Big THANKS to Cetin!

A potential symptom of infection with the MyDoom.B Virus is that you are you unable to visit your Antivirus vendors website or various Microsoft websites such as support.microsoft.com or windowsupdate.microsoft.com.

If you are experiencing these symptoms use the following procedure in order to be enable accessing these websites. Click Start, Run and type cmd and press Enter.

Under Command Prompt, ype the following commands and press Enter after each:

copy %systemroot%\system32\drivers\etc\hosts %systemroot%\system32\drivers\etc\hosts.old

del /F %systemroot%\system32\drivers\etc\hosts

echo # Temporary HOSTS file >%systemroot%\system32\drivers\etc\hosts

attrib +R %systemroot%\system32\drivers\etc\hosts




If you're running windows NT, you must restart.

For Windows 2000, Windows XP, and Windows 2003, restart isn't needed. In addition, you must type the following command:

ipconfig /flushdns

Note

For windows 9x/Me, click Start, Run type command and press Enter. Under Command Prompt type the following commands and press Enter after each. Restart isn't needed.

ren %windir%\hosts host.old

echo # Temporary HOSTS file >%windir%\hosts

attrib +R %windir%\hosts

Re:If you're unable to browse to Antivirus or Microsoft sites (MyDoom.B side effect), use the following procedure

My sister is having this problem. Is the My Doom virus the same as the Blaster Virus? She has had a problem for 2 days now. She is running Windows XP and she cannot get to Microsoft or Symantec. She is infected by the Blaster Worm. If I'm not mistaken you said something about hitting enter after your prompts in your message, we're you talking about after each line. Neither one of us are computer wizards, so I have another question. Will she have any problem fixing this. Also she has un-installed and re-installed the Norton Anti-Virus numerous times and she cannot get into the live update. Will she still be protected if she can't get the live update? How would she have got this worm. She just had her system upgraded to Windows XP, she had Millineum, brought her computer home to put Norton back in and that's when everything went wrong. I don't know if she was on the net before she installed it or what. PLEASE we need some big time help. Thanks.

Can you use the above commands if you have the blaster worm and it is keeping you out of Microsoft and Norton or do you have to use something else. I know you said this is for My Doom, but I thought that I would ask anyway.

Nope, NOT for Blaster

Sorry, I am a "bit" late with replying.Had to ask Cetin as he was so kind to provide the information !

In order to get rid of MSBlast, the simple steps are (one approach):

Disconnect the problem PC from Internet.
Download a MSBlast removal tool (use another clean PC) from an Antivirus vendor (Symantec, McAfee, etc.). One can transfer it to the floppy or CDR, etc. and launch it on the problem PC.
3. Install a Firewall on the problem PC.
4. Go to Windows Updates and download and install security updates.

Update AV definitions and perform a full scan for viruses.


The above steps are for the case when there are no further incidents and obviously cover an end user perspective (vs. networked PCs inside a company).

Even the procedure seems simple, could be incidents. For example, at step 4 one can get cryptographic errors and can't go further. Also, even after 1-5 successfully steps one can't acess AV updates for other reasons than the MSBlast (example: AV package bugs in automatic procedures).

Hope this helps.

In reply to: Nope, NOT for Blaster

Want to thank you for all your help. We still don't have it fixed. She has tried the blaster tool from symantec and she still cannot get to Microsoft or Symantec to get the updates. It is still in her computer. I don't know if we are doing the step by step thing wrong or what, but something is not being done right. Appreciate your help. Thanks for trying.

Meet the drop-resistant Moto Z2 Force

The Moto Z2 Force is really thin, with a fast processor and great battery life. It can survive drops without shattering.
