Firefox freezing when completing a download

Which is what I put down to Eset scanning the file as it doesn't do it without Eset installed/enabled

Whats up and how do I fix it?

cheers

 

thanks

have changed and will post back if any more issues

 

if you have Vista be sure to install SP2

 

I have been having this issue for a while. Had it in Vista and now in Windows 7. I have browser.download.manager.scanWhenDone set to false. Windows 7 x64 is up to date and running the latest version of NOD 32 64 bit version. Even for small files, it freezes for a long period of time and erkn.exe is using 25-50% of the cpu.

 

Yes. I tried it in the latest version of Google Chrome 3. When the download percentage reached 100%, the download manager froze and ekrn.exe process jumped to 25%.

 

when you download something from your browser, it goes into a temp file until the download is done, then the file is created.The anti-virus is doing it's job, by scanning the temp file before it's created.the delay should only be a few seconds, depending on the file size, sometimes longer but it's still normal what your seeing here.

 

Could you give us an example of a url of such a file so that we could try to replicate it with the very same file?

 

It happens on this file in both Firefox and Google Chrome.

http://sourceforge.net/projects/unetbootin/files/UNetbootin/372/unetbootin-windows-372.exe/download

 

I'm using IE8, Windows 7 x64 RTM, and ESET EAVBE 4.0.437.

That file took a massive 47 seconds to scan, during which ekrn.exe shot up to 50% and my laptop cooling fan went into hyperdrive mode.

And it's only 4MB

Definitely something in this file that ekrn.exe doesn't like.

This is a large upx-packed file with 32,17% compression ratio. It takes time to emulate such large files with advanced heuristics. If already unpacked, it's scanned in 1 sec. As for this particular file, we'll add it to the whitelist so that it's scanned quickly.

 

I guess you guys have runtime packers and advanced heuristics checked for real-time file system protection ? it tells you there can be a performance hit while having these checked, try to download it without those checked in the real-time advanced threatsense section.

 

They are off for real-time but on for Web access protection. I guess I can disable them and see if it improves. Thanks.

 

How many files are on ESET's whitelist?

 

I have no clue.

 

I bet it's over 9000!

 

Wow, so you think that ESET has had over 9000 FPs so far

 

Nah, I was just trotting out the 'Over 9000!' internet meme. I've seen the whitelist mentioned a few times and was curious about the numbers, that's all.
