I ran a gmer scan (gmer log below) and it showed sector 61: malicious code @ sector 0x12a18ac1 size 0x1fd. Does this mean I have a possible rootkit infection or some other infection?

gmer log of scan:

probably

Let's take a look with Rootrepeal

Install RootRepeal

Click here - Official Rootrepeal Site, and download RootRepeal.zip. I recommend downloading to your desktop.
Fatdcuk at Malwarebytes posted a comprehensive tutorial - Self Help guide can be found here if needed.: Malwarebytes Removal and Self Help Guides.
Click RootRepeal.exe to open the scanner.
Click the Report tab, now click on Scan. A Window will open asking what to include in the scan.
Check the following items:
Drivers
Files
Processes
SSDT
Stealth Objects
Hidden Services

Click OK
Scan your C Drive (Or your current system drive) and click OK. The scan will begin. This my take a moment, so please be patient. When the scan completes, click Save Report.
Name the log RootRepeal.txt and save it to your Documents folder - (Default folder).
Paste the log into your next reply.

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

My best guess is that this is an infection of your master boot record. I suggest moving to the HJt forum for further evaluation. Please follow this guide from step (6). Post a HJT log to the HJT forum and a Team member will be along to help you as soon as possible. You may wish to post a link back to this topic to see what was discussed thus far.

If you need any help with the guide, please let me know.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/242747/may-have-malicious-code-in-mbr/ 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 HJT 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 HJT 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 HJT 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 HJT 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 HJT Team member is already assisting you and not open the thread to respond. Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible

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

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
