Hello I hope this is the right forum area.... I have a laptop that was infected with a fake Anti-Virus program. That has been removed, with Malwarebytes, and combofix... The internet does not work now, I can ping from a command prompt any website and it replies. Through the Browser it does not, both Internet Explorer and Firefox. I checked to see they weren't going through a proxy. I also checked windows/system32/drivers/etc Hosts and it looks ok. I have also attempted to disable any startup items, still nothing. Scanned with Avast, Malwarebytes and Adaware come up clean. If I start the system in Safemode internet works great. Any ideas? I'd really appreciate any help someone can offer. Thanks alot!

Run sfc with the scannow option, this will scan and repair important Windows files.

Instructions

1. Locate your Windows XP installation CD. If you don't have one, you'll need to locate a directory on your system that's named"i386" (without the quotes). This directory may be on a hidden partition on your hard drive.

2. Go to Start, then to Run, and type in "SFC.EXE /SCANNOW" (without the quotes - and with a space between the SFC.EXE and the /SCANNOW). Then press Enter. (For VISTA, go to Start and type in the above information, then go to the top of the box and right click on SFC.EXE /SCANNOW and select "Run As Administrator")

3. The program may (or it may not) ask you for your Windows XP installation CD - please insert it at the prompt. If it doesn't ask you for the CD this means that it wasn't necessary to replace any files.

4. In the event the the system asks you for the CD, you must visit Windows Update immediately after the scan is completed (Please note that there won't be any confirmation dialog - the program will just exit without telling you anything).

5. If this doesn't repair the problem with your system other troubleshooting procedures are required.

I've ran the System File Checker, it looks like it didn't find anything. I also checked the system with LSPFIX, and ran netsh int ip reset , ipconfig /flushdns

Whats the next step, I'd really like to avoid reinstalling this machine if at all possible. Thanks for your assistance!

Please use the following software to provide us with information about your computer so that we can assist you.

How to Publish a Snapshot using Speccy

Try doing a System Restore in Safe Mode, choose a date prior to using Combofix.

If this doesn't work use the Last Known Good Configuration.

Without knowing what kind of computer you have I can't accurately make any further suggestions.

My apologies for stepping in here, but please do not do system restore. For one thing, it won't reverse everything ComboFix did and could further complicate your issues.

You still have remnants, I suspect, of the infection. Please follow the instructions in ==>This Guide<== starting at step 6.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Since you have run ComboFix, please include the ComboFix log in the new topic. Please be sure to include a description of your computer issues and what you have done to try to resolve them.

If you cannot produce any of the other logs, then please create the new topic anyway, include the information that you were unable to produce the other logs and why and include the ComboFix log along with a description of your computer issues.

I see that you have moved this to the Am I Infected forum, so I will leave this to the MRT.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic353886.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.
