New User with a search engine, hijacker virus/trojan/malware...

Recommended Posts

I seem to have been infected with some sort of malware that hijacks my search engine searches. I'm not entirely tech savy so I purchased the full version of Malwarebytes in hopes of ridding my computer of this problem. After I run a scan, Malwarebytes does in fact discover a trojan, but after my computer restarts, and I open any Internet program (firefox, chrome, IE) the trojan is back as is confirmed by an additional scan with Malwarebytes.

I followed the instructions from the "I'm infected - What do I do now?" topic and attached is the requested info:

Please advise on what I could/should do next.

BACKDOOR WARNING

One or more of the identified infections is known to use a backdoor.

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

I would advice 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 infection 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:

Help: I Got Hacked. Now What Do I Do?

Help: I Got Hacked. Now What Do I Do? Part II

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. If you decide to go through with the cleanup, please proceed with the following steps.

Download OTL to your Desktop

  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
  • Please tick the Scan All users. Next, click the Quick Scan button. The scan wont take long.
    • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time and post them in your topic.

OK so I've decided to just go ahead and reload my computer.

Can I keep my files? (pictures and school papers etc.)

Do I need to purchase a copy of windows or is there a way to get what I need without purchasing? (windows was loaded on my computer when I bought it from Best Buy)

Yes, you can.

Don't you have a CD or certificate that which indicates that Windows is genuine? Ask them about that. If not, you should buy a new one.

They don't give a cd when you buy a new computer at best buy anymore, instead you get the option to buy a cd. I chose not to buy the cd since nothing bad was ever going to happen to my computer. But let's just say I go to Bestbuy and they give me a certificate that says my copy of windows 7 is genuine. What would I do with the certificate?

There is a code that you should enter after reinstalling to confirm that your Windows is legit.
