ComboFix

While using ComboFix to clean up some infections, the tool seems to work fine until it reaches Stage 50. Then everything stalls with this last line:

' "C:\WINDOWS\system32\"' is not recognized as an internal or external command, operable program or batch file.

A log file therefore was never created.

After waiting for quite a while, I had to use task manager to stop the application. Then I restarted the computer and tried re-running ComboFix again thinking maybe I caused it to stall. But the same problem occurred. All in all, I have tried 3 times and each time, I get the same error. Good news is, after fixing my internet connection each time, I was able to browse without the previous problem of having my browser hijacked to ad sites.

Question is: what caused ComboFix to stop in its tracks and what ramifications are there? What is the next step?

Thanks,
HKT

You may have missed the prominently written advice in the header above: QUOTE: When posting your problem, do not run and post a ComboFix logs. ComboFix is a tool that should only be run under the supervision of someone who has been trained in its use. Using it on your own can cause problems with your computer. Any posts containing CF Logs will be ignored.

To receive help, you should instead provide a detailed description of your problem, detailed word-for-word error messages that you are receiving, screenshots of strange behaviour, and your operating system. This information is much more useful to our helpers than a ComboFix log. END QUOTE

Many have a problem accessing security sites when infected. If you have that problem you will need to use another computer to download the programs to a CD or other medium to download to the infected computer.

Many have a problem installing the programs after downloading. If you have that problem you will need to find the .exe for each program and rename them. Right click on each .exe and choose rename. Rename with names like sasex.com and madam.com. Then click on the .exes to install.

You may need to download manual updates to CD or other medium for each program, too. VERY IMPORTANT TO UPDATE!!
