Hi jazzymel,

This is a virus:

resycled/boot.com is a worm that propagates on local fixed and removable USB drives. resycled/boot.com may infect drives via autorun.inf file it created that runs a command each time the drive is accessed. Malicious files will be copied to a drives attached on infected computer.

Trojan Horse SHeur.CODS

Risk Level: Low

File Size: Varies

Affected System: Windows

1. Appears a message resycled/boot.com is not a valid Win32 application
2. Presence of autorun.inf files on root of drive

How to remove:

1. Download Malwarebytes Anti-Malware (mbam-setup.exe) and save it on your Desktop.
2. After downloading, double-click on mbam-setup.exe to install the application.
3. Follow the prompts and install as default only
4. Before the installation completes, check on the following prompts:
- Update Malwarebytes Anti-Malware
- Launch Malwarebytes Anti-Malware
5. Click Finish. Program will run automatically and you will be prompt to update the program before doing a scan. Please update.
6. Scan your computer thoroughly.
7. When scanning is finished click on the Show Results
8. Make sure that all detected threats are marked, click on Remove Selected.
9. Restart your computer.

Run either one of these tools, it will delete the bad autorun inf in each partition..
1.  Download and run this tool and follow the prompts:

2.  Please download ComboFix by sUBs:

You must download it to and run it from your Desktop
Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
Double click combofix.exe & follow the prompts.
When finished, it will produce a log. Please save that log and attach it in your next reply by pasting it in the "Code Snippet" or "Attach File" window.
Re-enable all the programs that were disabled during the running of ComboFix..

Do not mouse-click combofix's window while it is running. That may cause it to stall.
CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.
