I recently found that a lot of my day to day applications are loosing their icon. They are running fine but before that a cmd windows opens with c:\windows\system32\netupdate.exe (221 kb). ( I attached a screenshot)
Comodo antivirus checked the file but not virus found.
I also submitted the file netupdate.exe to you guys…
Hope this helps.
Using Windows XP SP3

Thank you very much for the update.
Have a nice day,
Should I also send a file that links with the malware? ( the ones without icon that sends me to netupdate.exe as in the screenshot)
I have this files all over my hard drive (initially uninfected applications). If needed I’ll search for one and send it to you.
Thank you very much,
Yes, you can also send that file (or files) and we’ll check it.
O.k. I will send you the files tomorrow in the morning.
These files keeps spreading in my computer as we speak so it would be great to stop or desinfect them somehow.
If it helps, there are some files that was not accessed but still looks infected.
Thank you very much,
i have doubts that your pc will ever be clean whatever antivirus you will use. as you said, uncountable things are modified, so maybe even a operating system reinstall wouldnt be enough to fix everything. who knows what changes have been done.
I have the same doubts, but in hope of a cleaner future for me and others I will upload some of the files.
In case some good luck strikes me, and those files can be disinfected after this, then I’ll buy the ■■■■
I Uploaded 3 Random files in the link you provided and below:
Happy to see that Comodo AV deleted Netupdate.exe but found 0 threads in all the files I mentioned and uploaded.
In case any other action is needed from my side, please reply.
Thank you for your support,
just for an example, use on demand “anti-malwarebytes free edition”. only as the “second opinion”. you will be surprised, but i am sure, it will find something.
even after that, the pc may not be clean. even if you have used all available antivirus programs, even the paid ones
The infected files are now removed, and system works fine.
Thank you very much for your support,
After the updates was changed to detect this virus, I got some new mp3 and jpeg files with the same infection.
These files are new and I think is just a false positive.
Can you please check?
Uploading the files through Comodo Antivirus Database | Submit Files for Malware Analysis
The jpg file looks uninfected in virustotal:
We are going to have a look at it and will get back to you after investigation.
Thanks and Regards,
I just received an email from you guys saying they could not find any virus with comodo and the current update (5613) on those files. And indeed, now when I scanned it’s not showing any detections.
The virus was detected when I copied those files on my computer ( and I clicked Ignore)
I see that the AV was last updated 30 minutes ago, was this false detection removed in the meantime or it was just something from my side?
Anyway, it seems to be ok now.
