Windows 7: BSOD and Run-Time error '6': Overflow when antivirus scanning

31 Dec 2011   #1

Windows 7 Enterprise 32-bit SP1
BSOD and Run-Time error '6': Overflow when antivirus scanning

My mom gave me an old laptop of hers, it's a Gateway M285-E running Windows 7 32-bit. At first I noticed that explorer wasn't working right, for instance, the entire C drive seems to be empty (except for two files) and some explorer windows are coming up without any words (see first screenshot), task manager included. I tried to Run AVG anti-virus scan, but it froze the computer everytime, so I uninstalled and not have avast! free on it. When scaning, the run0time error pops up each time sometime in the middle of the scan. A friend recommended Malwarebytes, so I tried to use that, but the same error pops up and sometimes I get BSOD after only having started the computer. Below are some screenshots of the problems, and atatched is my Windows_NT6_BSOD_jcgriff2 file. As can be seen in a screenshot, I could not get a system health report, the same error happens everytime I try even after restarting the computer.
If any other information is needed I will be happy to supply it.

Win 8 Release candidate 8400

There are several problems here that my partner and I are going to help you work through. I would suggest up front if you can do a clean re-install of win 7 it would be faster and easier.

That having been said, in your specs you have SP-1 in the crashes you dont.

Your OS version in the crashes is listed as "enterprise", which is not the best version to be running at home. Has that OS been modified in any manner?

As m partner is saying there are at least three separate malware apps running simultaneously. Thats never a good idea. Follow her directions for the removal of them.

> You still show AVG in the DMP files.
It is often a contributing cause of BSOD'S .
Please remove and replace your AVG with Microsoft Security Essentials AT LEAST TO TEST

Download tools and utilities | AVG Worldwide

> Same with Avast > another contributing cause of BSOD'S .

Remove via

> Download & install

Microsoft Security Essentials - Free Antivirus for Windows

> Please download the free version of Malwarebytes.
Update it immediately.
Do a full system scan
Let us know the results at the end.

Malwarebytes : Download free malware, virus and spyware tools to get your computer back in shape!

> Your crashes were caused by memory exception (probably due to the multiple Anti Virus you are running).

Please run these two tests to verify your memory and find which driver is causing the problem.

If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+

2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Windows 7 Enterprise 32-bit SP1

The computer that needs help does not have SP-1 as far as I know, and it's running Window's Seven Professional. I can't do a clean re-install because my mom (who gave me the computer) threw away her disk after using it. Just wanted to let you know that in-case it would change anything. Thank you very much for the help, I'll let you know how the rest goes when I've completed it.

Windows 7 Enterprise 32-bit SP1

I had trouble with the avast removal tool so I'm not sure if it worked right or not. I think it did, since I can't find avast on the computer anymore, but the action center is asking me if i want to turn Avast back on, so maybe it is still there and just not on?

While trying to install microsoft security esentials, I received a notice that An error has prevented the installation. Error code 0x80070643. I tried restarting several times, but the same thing happened.

Attachment 190998

Also, I'm not sure how to install Malwarebytes because the setup window is useless (only available options are minimize and close)

Your options are at best limited. If there is a legit license for win 7 on that machine you can download a win 7 image and burn it to DVD>
