Hey guys, new to the board and im hoping you guys can help me out on this one. My computer was infected last night when i visited a website using firefox. Windows firewall turned off on its own, and now i have redirect issues using yahoo search. Seems to redirect to clickover.cn when i use noscript on firefox. Scans with Avg, malwarebytes, and adaware all failed to get rid of the infection. I tried running system restore to an earlier date, which seemed to make the problem worse because not only did the restore fail, but upon restart it added a fake antivirus scanner. I ran malwarebytes again and it seemed to get rid of this fake antivirus program, but the redirect issue is still there. I have read other peoples post on this issue and i went ahead and downloaded rootrepeal, but i'll wait until futher instuctions before running it or doing anything else. Any help would be very much appreciated.

Could you please post your latest Malwarebytes log, which can be found under the logs tab in the program, and then go ahead and run Rootrepeal and post a log. Here are the instructions if you have any trouble:

Please install RootRepeal

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K
Unzip that to your Desktop and then click RootRepeal.exe to open the scanner.

*Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the FILES tab, then click the Scan button.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Please note: If Rootrepeal fails to run, try this step: Click Settings - Options. Set the Disk Access slider to High


Note 2: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

Please right click on this item in RootRepeal, and then select Wipe File. Then right after that, reboot and run a Malwarebytes Quick scan and post back the log.

If everything is good then:

Create a new Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
Go to Start > Programs > Accessories > System Tools and click "System Restore".
Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
Then use Disk Cleanup to remove all but the most recently created Restore Point.
Go to Start > Run and type: Cleanmgr
Click "Ok"
Disk Cleanup will scan your files for several minutes, then open.
Click the "More Options" Tab.
Click the "Clean up" button under System Restore.
Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
Click Yes, then click Ok.
Click Yes again when prompted with "Are you sure you want to perform these actions?"
Disk Cleanup will remove the files and close automatically.
