I ran the ESET Scanner on my laptop a couple times, but both times it crashed & I couldn't get rid of the virus. I know it found 2 files infected with "a variant of Win32/Injector.Autoit.SP trojan". Is there another scan I can run instead? Thanks!

Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

rKill.exe: http://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

* Double-click on the Rkill desktop icon to run the tool.
* A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
* If not, delete the file, then download and use the one provided in Link 2.
* Do not reboot until instructed.
* If the tool does not run from any of the links provided, please let me know.

If normal mode still doesn't work, run the tool from safe mode.
When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.

 

 

Download Malwarebytes' Anti-Malware Free (aka MBAM)
* Double-click mbam-setup.exe and follow the prompts to install the program.

* Do Not Accept the Free Trial Option at this time ....... please
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform quick scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.
Be sure to reboot the computer if required after you post the log.

 

Thank You -

See previous topic
http://www.bleepingcomputer.com/forums/t/514035/removed-trojan-but-now-getting-inappropriate-ads-what-do-i-do/#entry3208716

Sorry was unable to be on the last couple days. this injector Trojan has backdoor capabilities so I want you to know this ....

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

I think it would be better for me to reformat my computer. Is there anywhere I can find out how to do it?

If you need other info ask in Windows 7 and they will be glad to assist.
