    i am using AVG Free edition, updated very frequently and recently, approximately once a day randomly, AVG's resident shield comes up and tells me that the worm/nachi.B virus has been found in C:\windows\system32\drivers\svchost.exe, i run AVG and it says it has healed the virus but for some reason it keeps coming back, ive also deleted the svchost file from that directory and still no help.

    using win xp sp1, vaio p4 2.4ghz, 512mb

    how can i make this thing go away!!!!???

    Please Download HijackThis from here. Make a new folder for the program and then open it, click Scan. When it finishes scanning, do no remove anything but instead save the log and post it here.

    Then we'll be getting somewhere

    OKay, well that log looks clean, so I suggest trying to run an online virus scan from the following link.

    @all
    Please scan your computers in safemode
    Then let the scanner delete the files he find.

    Thats a safer way

    I'm not sure if anyone reading this has had any success in removing this virus completely, but the problem i'm having is the same as these two. The thing is, simply deleting the files will not cause the virus to dissapear, because it enters through open ports. I've found that with this virus, much like it's sister-virus Blaster, if you are using windows XP, you can turn on the Internet Connection Firewall in the connection settings for your internet connection. This will block whichever port the virus is using to crawl back in. However, i'm pretty pissed off because I'm using dialup, and there should be no need for me to be using an internet firewall - i notice that things run slower, like network connections on IRC. Anyway, this will solve your problem untill this damn thing internally combusts in June 2004, so let's all wait and see, shall we?

    If you aren't using Windows XP, you might think about buying a firewall program such as ZoneAlarm. I would also assume hardware firewalls contained in internet routers will work as well.

    I also recommend downloading and running Stinger, which will remove not only the virus files for Blaster and this varient, but the some of the other registry stetings it may have changed, etc etc.
