Morning!
So here's the deal for thos eusing MSE. Download a large file, say an nVidia driver (say from here: http://us.download.nvidia.com/Windows/270.61/270.61-desktop-win7-winvista-64bit-english-whql.exe) and see if your MSE is doing the same thing my MSE (and the MSE on the HTPC and spare laptop) doing as shown in the video below (best watched in 1080p).

The DL corrupts, MSE interrupts the DL and the DL fails.
Disabling MSE's resident file monitor cures the problem.

So why is MSE doing this and not other AV? And why does it only seem to affect IE(8/9) and Firefox and not Chrome? I tested it in all 3 browsers many times and Chrome seems to not have the issue.

Running FF as Administrator doesn't cure the problem either.

This is the latest stable MSE and it's the first time I have encountered this problem as well although maybe it was always there and I just never noticed it...
 
just tested it with the file you said and it downloaded fine with IE9
MSE didnt do anything

update
also just tested it in FF4 and again no problems

I've also had this problem in the past, but it was intermittent for me.

I've given up on MSE. I used to install it on friends PCs I used to fix but it always used to spaz out with various problems, always on fresh XP sp3 installs.

Maybe it's a combination of things then? My connection is 30Mb and it starts off at above 3MB/sec anyway so maybe because of this speed MSE gets confused? What connection are you guys on?

I an replicate the issue on 2 different PCs, one of which is wireless as well btw. I seem to recall it only occurring after being upgraded to 30Mb as was on 20Mb before with no issue with downloads via the browser while MSE is active.

Hmmm

I dont know if its relivent, but if you got the latest VM Superhub with 20->30mb upgrade there is a firmware bug that will corrupt files if you turn the inbuilt firewall off.

Click to expand...

:eek:


That might just explain the whole thing then because i have disabled the firewall and all services on it bar the DHCP as I'm only using it as a modem (have my Netgear WNDR3700 as the router).

Although it doesn't explain why it's perfectly fine when disabling MSE resident scanenr though.

It could be an older MSE program engine perhaps, I note that MSE was installed on all machines at the same time and it appears MSE does not update the program when it updates definitions so my program will be old if newer ones are out - Can't check until I get home though.

Either way I don't like the superhub anyway, why they could not just dish out a bloody modem.....

Aye I was just thinking, I will tether my phone's 3G and test when I et back, at least that will confirm if it's connection related or solely MSE related!
 
It has to be in relation with the version of MSE I have too though because otherwise there'd be no reason why it works perfectly when MSE's file scanning shield is turned off!
 
I don't have any high hopes for it though as I think it's something....something something ;)
 
I used to have that problem with Kaspersky. I resolved it be adding the offending program to the exclusions list ie itunes wouldn't download ios, added to exclusions and it was fine.

I now use MSE 2 with no problems at all. Using virgin 50mb for info.
 
Thing is, adding Firefox to the excluded list would mean the resident scanner doesn't scan web content which might be a bit risky for sites with potentially infected ads and stuff (which has happened before to people!)

I see VM have a firmware update out for the Superhub so will try this as well.

Well, at least I have a few things to try!
 
I've just seen the thread about the firewall off = borked downloads. They seem to think it's IE8 only and not in FF4 so maybe that's a separate issue. Although that won't be my issue I just realised because my router is in the hub's DMZ so the firewall being on or off would have no bearing on the data being communicated via the WAN<>LAN!

This is interestingly troublesome, and I like it!
