Problem with Bios and AVAST ???

Avast Free Antivirus / Premium Security

Hello @all :slight_smile:

I found a little problem with Avast.

Last month i update my Bios Version from 1.50 to 1.60 to 1.70.

So i go to the site where i became my new Bios and download it. Ok so far so good. Then i scan with Avast the zip and all is ok.

Then i try to install the Bios but it fails. Ok i think the download was wrong so i download the Bios for another 4 times scan it and every time the install failed.

After that i try it a last time from the same site but this time i dont scan it with Avast and the result was that the installation passed.

Is Avast something changing / written by scanning ???

Here is the site if you need to try :slight_smile:

No it shouldn’t…
Are you using the Home version of avast? It couldn’t ‘repair’ an infected (or false positive) executable file automatically.

Yes im using the Home version. There is nothing to repair because Avast tells me that the file is Clean. ;D

Hi polonus

Thanks for the information, but now remaind the question open why the downloaded zip files after scanning can’t be installed but without scanning it goes. Hmmmmm

Not sure how avast! could damage a file just by scanning it? There’s probably something else going on eg. the files you are downloading don’t somehow get downloaded in one piece …

Hello M2

I download every file in one piece there aren’t problems by download.

Hi polonus :slight_smile:

Thanks but i think if i forgot the password then i must format the HD partition because i use True Crypt. 8) And to remember all my passwords Forums, Bank, E-Mail and so on i use the KeePass. All Opensource and maybe better then the Bios Password (i think) ::slight_smile: 8) ;D

I have got an issue more or less like this and there were behaviors (can’t prove that is Avast) indicate an update of the file.

My zipper program is Winrar. When I double-click a file inside an archive (in case a video), winrar extracts the selected file to the temp folder (the avast icon begins to spin), media player plays it, and at the end I close Media player and after I close Winrar. Well, before I close Winrar, it shows me a message like:the was modified. Do you want to re-add it to Winrar? I didn’t like this happening and always responded NO. But it looks like there is the possibility: File modifications.

BlackSheik showed one. I showed other. Beside any speculations, I think it is a good idea ask to the avast architects this unproved, but plausible possibility.

No, avast! really shouldn’t modify the scanned file (actually, it opens the file in read-only mode, so it shouldn’t be possible at all).
I’d suggest to compare the files to see the differences, if there are any. (so, for example, if WinRAR announces that the file was modified, don’t close the dialog, go to the TEMP folder, find the mentioned file, copy it somewhere else, extract it from the original archive to a different location and compare these two files - e.g. using the FC /b command.
