My windows xp sp2 computer has been crashing every couple of days during the past couple weeks. The screen blacks out suddenly and restarts. Today I checked my AVG free, which happily reported everything is clean and clear, but I checked the logs and they tell a different story. The last successful scan 2 weeks ago reports the following:
Inline hook ntoskrnl.exe _abnormal_termination+0x20B -> 0x804E2ED7
Subsequent full and rootkit scans yield no results and only report scanning a few thousand objects instead of the hundreds of thousands of objects reported in each scan prior to the one which found the inline hook.

An MBAM scan only found and deleted a temporary file (PUP.Optional.Amonetize.A).

However, besides the rare restarts, I have yet to notice any other effects, so I may be overreacting. I greatly appreciate the professional advice and thank you for your services.

Hello Wereducky
To find what's wrong we should get a deeper look. Please follow this Preparation Guide, do steps 6,7 and 8 and post in a new topic.
Let me know if all went well.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

You're welcome!

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 3 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
