Some problem with uploads

greetings,

i ma trouble uploading files to 4shared.com if i enable web shield. the upload either will stop on beginning or doesnt start all. if i stop the web shield serivce, the uploads are running good. so far this only happens to 4shared.com uploads. any solution ?

I have no problem uploading files to RapidShare or 4shared.

What is your firewall ?
Are you getting any errors, if so what ?

No firewall. Rapidshare are oke. the only problem is with 4shared.com. there are no errors. but the upload wont start or will stop after few kb uploaded.

Just that WebShield (avast) does not scan upload traffic, so, it’s not avast at upload.
Maybe something (data) is downloaded, but, again, avast shouldn’t block, just scan.
Are you using Windows XP or Vista? Isn’t it firewall blocking the upload? Are you logged into an administrator account?

Well that would tend to confirm it isn’t the web shield, otherwise you wouldn’t be able to upload to rapidshare either (but as Tech says the web shield doesn’t scan outbound uploads. So there is something that is conflicting, what that is, is the 64 thousand dollar question.

What other security software do you have ?

You most certainly need a firewall as a part of your security setup even if you have a router/hardware firewall.

Are you trying to upload the same file into both servers?
Isn’t it an access denied (not enough rights) problem?

It’s a known issue with WebShield! WebShield at least sometimes causes 0 bytes to be sent for file uploads.

What know issue, it is unknown to me, care to expand ?

The only time a 0byte file has been returned to my knowledge is trying to upload a file to virustotal, etc. whilst it is in the chest (a protected area) and even then the web shield doesn’t scan uploads. Otherwise it would have alarmed on the file I have just uploaded to virustotal within the last 10 minutes.

Im using Winxp SP2. No firewall. I have no other security software . Only avast running. Im on the admin account.

This problem only occurs when webshield are running, If terminated, then upload are smooth .

The problem is the inconsistent results works at one upload site and not the other, if it were truly only a problem with the web shield it wouldn’t work for all uploads. Not to mention as has been previously said avast’s web shield doesn’t scan uploads.

I have just signed up for a free account at 4shared and uploaded a file with no problems. I used firefox, my default browser with the web shield enabled.

4shared test upload image.

I have also been able to download it. So it appears to be working fine for me.

Activate logging in WebShield:

  1. Edit \data\avast4.ini file
  2. Find the section [WebScanner]
  3. Add the line:
    EnableLogging=1
  4. Restart Web Shield in XP (terminate and start again) or whole PC in case of Win98
  5. Browse (trying to access some webpages and upload the files)

The log file are \data\log\ashwebsv.log and ashwebsv.ws.
They would be accessible when WebShield is terminated again.
Post them here or send by mail to rypacek (at) asw.cz
After that, disable the logging to avoid a big log file.
