Boot critical file is corrupt
The problems started yesterday when my computer went to blue screen and automatically shut down and restarted. This happened twice, then I did an AVG scan in Safe Mode. It placed several infections and a few malwares into the virus vault. However, it "did not test" dozens of files because they were "locked". There were Boot directeries that were listed among the locked files.
I restarted in Normal Mode, and got a message that Windows found a malicious file and "partially removed" it. When I clicked on the message to find details about the file, this webpage popped up: Encyclopedia entry: TrojanOS/Alureon.A - Learn more about malware - Microsoft Malware Protection Center
So the infection was TrojanOS/Alureon.A (edited to add: the smiley face appears where : D [without the space] is in the trojan filename)
About an hour later, the computer crashed and restarted again, then again a few minutes later. I did another scan and no malicious files were found.
When I turned the computer on 20 minutes ago, I got a screen telling me that the computer was unable to start, and Windows was searching for solutions. It apparently worked because I'm using the computer now. However, when I clicked to see the details of what happened, I saw this: "Boot critical file c:\windows\system32\kdcom.dll is corrupt".
So I don't know if it fixed the file or if it's still corrupt. I'm concerned my computer will have trouble rebooting. Thanks for any help in advance. What do I need to do to fix this problem?
Should I download Windows Defender Offline? If so, would I need to uninstall AVG to get it to work properly?
