I have the same problem but it "infected" powershell.exe I am using the Free version
I just tried to download and run Amazon LumberYard. AVG stuck the file in the virus chest and said it was infected with idp.alexa.51 - definately a false positive.
Did someone 'unfix' this
Anthony, let's have a look into this together.
Do you have the latest version of AVG AntiVirus Free/AVG Internet Security installed on your device? To find: Open AVG Internet Security > Menu > About.
Keep us updated to proceed further.
AVG claims just now to have detected the idp.alexa.51 virus in a 5-line batch file that I WROTE MYSELF!!! I'm pretty sure I didn't accidentally write a virus. I'm not clever enough.
Hello Alex,
We regret for the inconvenience caused. We are sorry for the delay in responding. What exact type of files you are unable to restore? Based on type of AVG's detection, only executable files should be removed and no data is removed. We also suggest contacting 'Sage' support to get assistance to backup/restore the data. Thank you.
I have also had this problem. Currently attending school for Info Sec and have downloaded several tools which aren't dangerous and come from a valid source, primarily Wireshark and ProcessExplorer.
Have just bought a cheap digital microscope. Drivers are dated 2004. On install of drivers AVG is showing this threat - it is not clear to me whether this is a valid threat or a false positive on old drivers.
Hi Alan
Your colleague Karthikeyan answered my second question with her comment: “This issue will be resolved automatically in next update.”
As for my first question though, I looked at the article you linked Flo to don't think it answers my question (it's to do with, I think, how to submit a programme file to AVG for them to test whether it really is a FALSE positive?)
What I was hoping to know was a more general fact:
Is it generally possible, or impossible, for an .exe file that has been on a computer for years, and is in use daily, to become compromised by some sort of malicious code that’s been picked up recently – in other words, can a newly introduced virus or malware on occasions somehow RE-WRITE an existing .exe file, to embed something malicious inside it?
Can you help me understand this? Thanks.
Same thing happened for windows 10 Pro 64bit
I was installing Western Digital 'WD Discovery'
got error:
C:\users\brand\AppData\Local\Temp\BD1E.tmp.exe
Threat name : IDP.ALEXA.51
Ok I have the same problem. AVG has falsely IDed several components of my Sage accountancy software. Ive followed your instructions here, i.e updated to the latest 21/07 update, and Ive tried to restore the quarantined files. Two restored fine, but two have failed, giving the errors "Removal item in wrong state" and "The object identifier does not represent a valid object".
I can now start Sage but the components that have failed to restore are responsible for serving the data so I cant access our company accounts. There is a backup but its several days out of date and will mean a LOT of work to make it current.
What do I do? As you can imagine this is rather mission critical.
Hello,
I saw this bug was opened on July 2016
Even after so much of time, I am getting the same issue. And I am 100% sure that its false positive. I am an application developer. I got this warning in an application which is developed by myself only. I am very sure that I have not used anything which will make antivirus think that I am hacking.
There is one more thing, I was not getting this warning earlier and suddenly it started showing the error. I have done nothing much just changed some variables. Which should not trigger this, I am sure.
Can you please justify this random behaviour? Will all my customers, who have AVG antivirus installed, will get this threat? If it is so, It will be a huge problem for me.
Hello Emre,
This looks like a false detection by AVG.
May I know whether you are using the free or paid version of AVG Antivirus?
If it is the paid version, get connected with our technical chat support using this https://support.avg.com/support_tech_chat link to get further assistance.
If it is the free version, please create your own post on this community which will help us to provide further assistance.
Thank you.
Hello,
I registered solely to report, that I have a similair issue.
Starting today, AVG reports noumerous exe files of programms I have on my PC since a long time.
Your reply means that I can rest assured and it's not likely, that I have several infections in exe files of well known programms, such as genuine software by logitech for my mouse etc?
However, I was not able to restore all of the false positives and a mail app, downloaded from the microsoft app store was destroyed by AVG and can not be restored, uninstalled or re-installed by AVG or the store app.
AVG is screwing up my work PC.
Please solve this issue, or I have to leave ship
Well, I spoke too soon 
I'm having the same problem. I open Outlook 2010, Grammarly crashes, Outlook and then I get the same IDP.ALEXA.51 threat detected. I have created exception and AVG still show the same screen over and over and I can't use my Outlook. I really need this to work!!!

best.
Emre
Hello Karthikeyan
Thank you so much for such a very quick response.
I'm glad it's 'just' a problem with AVG and not a real problem with my computer!
Thank you for your help regarding how to avoid further trouble.

We're sorry to know that, Anthony.
This seems to be possibly a false positive. In this regard, we suggest you to submit a false positive request by visiting this link (https://www.avg.com/en-us/false-positive-file-form).
Before proceeding with that, update AVG once & then restart your computer to check if the issue persists.
To update : Click on refresh icon beside Virus definitions that is available in the homepage of AVG Internet Security.
