Hi, Thank you for your post! The file akaqudenenorixat.dll is most likely a componenet of virus\spyware. I would suggest you launch your antivirus software and perform a full system scan. Or you can perform the following steps: Step 1: Update the definition file for the antivirus program. If you do not have an antivirus program installed, I would suggest install Microsoft Security Essentials to protect the system from being infected with virus. Step 2: Disable and Enable System Restore to clear the virus permanently. Many viruses infect restore points. In order to clear the infected files permanently, we should clear the restore points. Please use the steps below to do so: 1. Click "Start, input "SYSDM.CPL" (without quotation marks) and press "Enter". 2. On the "System Protection" tab, click to turn off System Restore on all drives, and click "OK". 3. Please repeat the above steps to enable System Restore again. Step 3:Boot your computer into Safe Mode and then run your antivirus software on your computer to scan for and remove any possible Virus and Malware infections. 1. Restart the computer. 2. Keep pressing the F8 key until the Windows Startup menu appears. 3. Choose "Safe Mode", and press "Enter". 4. Run the computer in Safe Mode. 5. Start your antivirus program and scan the system in Safe Mode. Step 4: Scan for virus in Safe Mode with Networking Note: If you are using a cable modem or home LAN connection, please start from item 1 below. If not, please skip items 1~3 and go to item 4 directly. 1. Restart the computer. 2. After "POST" (the Power On Self Test usually has a text mode screen at the beginning when a system boots up), keep pressing the F8 key until the Windows Startup menu appears. 3. Choose "Safe Mode with Networking" and press Enter. 4. Please open Internet Explorer and visit http://safety.live.com 5.
