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!
