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.

This is my first post. ndis.sys is infected with a trojan horse. I could really use some help getting this file fixed/cured. This is a laptop running XP Pro SP3. I have AVG 8.5, and have tried cleaning this infection with Spyware Doctor, Malwarebytes, and multiple scans with AVG. AVG seems to detect it ok, but will not clean it. Thanks in advance for any help you may be able to offer.

Here is the Malwarebytes log. I did everything as instructed...but when I opened SuperAntiSpywareFree after the scan...there are no logs. Also, any and all network connection/devices in device manager all show the yellow exclamation mark on them and I have not had any success in reinstalling their drivers. Starting to look like a reinstall of windows.

After a quick glance at the log, I have to agree with you
I think it would be prudent
