I have a virus that pops up and asks for password, will not load windows won't let me go to boot menu or bios. Is there a way this can be fixed?

See if it will let you boot to safe mode with networking then run SDFix. Restart your computer After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually; Instead of Windows loading as normal, a menu with options should appear; Select safe mode with networking, then press "Enter". Choose your usual account. Download SDFix.exe and save it to your Desktop. Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with SDFix or remove some of its embedded files which may cause "unpredictable results". Click on This Link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask. Remember to re-enable the protection again afterwards before connecting to the Internet. 1.Double click SDFix.exe and choose Install to extract it to its own folder on the Desktop. Please then reboot your computer in Safe Mode by doing the following : Restart your computer After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually; Instead of Windows loading as normal, a menu with options should appear; Select the first option, to run Windows in Safe Mode, then press "Enter". Choose your usual account. 2. Open the c:\SDFix folder and double click RunThis.cmd to start the script. Type Y to begin the script. It will remove the Trojan Services then make some repairs to the registry and prompt you to press any key to Reboot. Press any Key and it will restart the PC. 3. Your system will take longer that normal to restart as the fixtool will be running and removing files. When the desktop loads the Fixtool will complete the removal and display Finished, then press any key to end the script and load your desktop icons. 4. Finally open the SDFix folder on your desktop and copy and paste the contents of the results file Report.txt

Sorry, but at what point does the password box pop up and request your details? Are you able to reach the standard loading screen? If not, do as stated above and enter Safe Mode. The SDFix.exe program should do the trick but follow the instructions exactly - word for word! It won't work if you have anti-virus programs interfering with the fix. Good luck =) http://www.pcfixreview.com
