Avira Support Forum

Hi guys,

I am an new member of this forum, but i spent some time reading posts that could be connected with my issue. Well, i am sorry if this issue already has been reported by some other member.

Problem is, that since june i could not perform full system scan. It started several times, since i made scheduled scan every sunday at noon, even i started it manualy, but it runs for about 20 minutes and then ends unexpectedly, without any error message. I also tried to run manual scan of hard drives and then i got this message:

avscan.exe - Application Error

The instruction at 0x011ddf27 referenced memory at 0x00000000. The memory could not be read. With Ok taster for closing the error window and scan progress window.

Is possible that i have a virus or some other kind of malware, since i finished system scan with Spybot S&D and Malwarebytes and they did not find any spyware or trojan horse, or that is an Avira Personal error?

Thanks in advance for your help!

Hi Lambda1,

Please try to disable Spybot Tea-Timer.

Hi Lambda1,

Please try to disable Spybot Tea-Timer.

Sorry, but TeaTimer is not active, since it uses a lot of computer resources. Windows 7 Defender is also deactivated, as recomended. Only active antivirus and antispyware software is Avira AntiVir Personal. Should i post here a log file or something? Maybe it will help in solving this problem...

Hi,

Please post here the HJT log. Instruction is here. Also, please make sure that the Avira is fully upated and verify the following: open Avira -> Configuration -> tick Expert mode -> Scanner and make sure that the "Follow symbolic links" is not selected.

I've got the same problem! I can't perform full system scan. This is the error:


avscan.exe - Application Error

The instruction at 0x0a52dca referenced memory at 0x00000000. The memory could not be read. With Ok taster for closing the error window and scan progress window.

What should I do?
I look forward to your reply!

I don't know if this is thread is still open, but I have the same problem with Avira 13 Free: "The instruction at 0x011ab112 referenced memory at 0x00000000. The memory could not be read." (yesterday the address wasn't 0x00000000, but I didn't write it down).

I don't know if it's related, but when I try to manually update says: "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item."

I'm on a Windows 7 pro 64. I don't have Microsoft Security Essentials installed. I do have the Comodo Firewall and Malwarebyte's Anti-Malware (only for manual scans, otherwise disabled). I closed the Comodo Firewall and tried again, with no change.
