Greetings. In the past 2 days I tried to run a full system scan on avast and right about at 3-4% I get a blue screen and my computer reboots. Is there any way to solve this and find out what’s causing it?
any other security programs installed…like more then one antivirus?
Nope, just avast.
attach OTL diagnostic log, then maybe essexboy can see the problem. http://forum.avast.com/index.php?topic=53253.0
The OTL and Extras texts as you asked.
First thing to do will be to remove the adware… What file is Avast scanning when it blue screens ?
Please download AdwCleaner by Xplode onto your desktop.
[*]Close all open programs and internet browsers.
[*]Double click on AdwCleaner.exe to run the tool.
[*]Click on Scan.
[*]After the scan is complete click on “Clean”
[*]Confirm each time with Ok.
[*]Your computer will be rebooted automatically. A text file will open after the restart.
[*]Please post the content of that logfile with your next answer.
[*]You can find the logfile at C:\AdwCleaner[S1].txt as well.
I didn’t notice which file it was but I can run it again and try to find which it is. I also run aswMBR. Here is the log. I will also download adwCleaner and post the log asap.
This is the log from the adwcleaner.
Could you run a scan please and see if it fails again
Alright will do.
Well I tried to run a full scan but I got a blue screen again, though this time the scan was on for a longer period of time. Also when the system rebooted, a check popped up. “Checking file system on C. One of your disks needs to be checked for consistency.” After it was done the system rebooted again, and it started normally.
I wonder if Avast was trying to access a corrupted area of the disc. Did you notice the file or folder that Avast was scanning at the time ?
I tried but the files that were scanned were changing really fast and I couldn’t get the one that caused the blue screen.
Panos93, did you re-run the scan after the Normal boot and after the disk check/repair ?
After the repair was done did you see if it had fixed items ?
I recall there is actual file (*.log or *.txt) located either on the “root” drive or the “Windows” folder that contain the info of what occured during the execution of the CHKDSK command before bootup…however, this may be for XP O/S. Newer O/S there may be no log on the disk but rather in the Wininit Event in the Application Event Viewer. A thread on it: http://www.sevenforums.com/general-discussion/96932-location-chkdsk-log-file-after-scan.html
Essexboy, run a CHKDSK from command prompt and see if clear ?
Nope, I haven’t tried to scan the system again, but I could if you wish.
Essexboy should be back awake in several hours…let him answer.
In the mean time…try to find the CHKDSK log that was created…either on the HDD or Event Viewer.
Best link to describe where to look: http://www.sevenforums.com/general-discussion/96932-location-chkdsk-log-file-after-scan.html
Post the log…
You can also within Windows do a CHKDSK…you can run without a repair (read-only mode) to just see results.
Go to Run Command (CMD)
Type chkdsk (Type “/” and the drive which you want to check with it, Example: chkdsk /C)
Wait for it to finish and post results
These are the results when my system rebooted and did the check. Do I need to do CHKDSK within windows aswell?
Go ahead and run it in Windows now in Read-Only mode and post.
It’ll give Essexboy a before & after…hopefully the “after” is “found no problems”. 
Well I run it, but the thing is it’s on greek and I m not sure you are gonna get something out of it.
Tried to translate in the best way I could.
