Can't log on to windows after initial scan

Hi
I have Windows XP and I had the XP Antivirus malware on my computer and downloaded Avast home edition to get rid of it. It went through a scan which recommended a pre-boot scan due to the many ways the malware enbedded itself. I rebooted the system and it seemed that Avast recognized many areas where spyware and malware had embedded itself including amdin rights, etc. The system check went a long time and when I came back the system was at the logon page. When I cliked on my icon it seems like it wants to connect and then it goes through the shut down procedures. It tried to sign on in the same way in Safe Mode both with my name and Administrator and experienced the same thing. I can’t even log on to my system to deal with the issue. How can I resolve this?

Same thing for me. Same day… If you find a solution - please notify. I don’t want to reinstall XP since I have lots of critical information on the disc. HP Laptop.

If you haven’t already got this software (freeware), download, install, update and run it, preferably in safe mode and report the findings (it should product a log file).

Can’t run nor install any software - I can’t log in to Windows XP at all or do anything at the start/log in page. Can’t start in safe mode or log in as administrator. I’m stuck at the log in page. When clicking at a previous account it’s after 1-2 seconds saying. Logging out. (back to start screen)

This happened in the first scan after restart - before the log in. (Blue screen)

As a first time user I got a message - virus - trojan found. The virus was in system folder. But what normal user should choose “do nothing” to a trojan warning. I choosed delete. That might be wrong but now it’s to late.

Next time I get a trojan warning - should I keep the trojan to be "safe? Why use Avast?

same issue - Another user that needed to reinstall XP after trojan warning.

I don’t know if a repair install of windows (I have never had to do this) might manage to get you through this or not. It is effectively an over install, it shouldn’t effect other data files, but there is always a risk (just ensure you don’t have it format the partition).

When you boot you would have to interrupt the boot, clicking the delete or escape keys to enter the BIOS and set the first boot device to your Optical drive and second to your HDD. Then put your Windows CD in and reboot, that should recognise you have windows installed and you should have an option to repair.

If this is successful you would have to apply any service packs and security updates to ensure your OS is up to date.

I had same problem this morning. What i do is using System Restore to recover the user profile for login. Tomorrow i plan to do into Safe Mode, indo System Restore then do the scanning.again.
