Don't know wat 2 do with cmd.com etc... files

  1. Hi guys & gals,

    I'm not the brightest spark when it comes to computers, so I need some help. Every time I go to run 'cmd' a box appears saying. 'cmd is not a valid Win32 application'. I know I have a virus although I ran numerous programs and none detected the problem.

    I found 7 files in system32. cmd.com, ping.com, regedit.com, netstat.com, taskkill.com, tasklist.com, tracert.com which all have 0bytes in size but all have a 4KB size on disk. To find these files I had to uncheck 'Hide extensions for known file types' & 'Hide protected operating system files'.

    I have placed them all in a file on my desktop and tried scanning them but they are all clean. Although I can now run 'cmd' and 'ping'.

    So I was wondering are all these files bad? What should I do with them? Delete them?

    Hope some1 can help pls. Cheers guys!

    Very Important: Before deciding whether you should clean or reformat your system, go and read this thread HERE and decide what it is you want to do.

    If after reading the above, you wish to clean your system, do the following.

    Go and read the Viruses/Spyware/Malware, preliminary removal instructions. Follow all the instructions exactly.

    Post fresh HJT, AVG Antispyware and Combofix logs as attachments into this thread, only after doing the above.

    Also, let me know the results of the AVG Antirootkit scan.

    Regards Howard :)
