[2008-04-27 @ 14:21 EST] <Ultima> This was a simple false-positive that has since been fixed by the ALWIL team.
Solution: Update your avast! virus signature/definition database.

No, µTorrent as downloaded from http://www.utorrent.com/download.php does not contain any viruses. If your antivirus software insists on it, then either its virus signature database contains incorrect/bad signatures, its heuristics engine is red-flagging any executable packed with UPX, or your computer is actually infected already, and some other virus is infecting any new executable you download. Assuming it's a virus signature and/or heuristics problem (they're the more likely causes), you might want to email the avast! people and complain about the problem.
I just downloaded both linked executables from the (official) µTorrent download page and scanned them using (the very well regarded) NOD32 -- nothing.

These hashes match with the hashes of the files as they have been for few weeks/months now since they were first uploaded.
And uh, quick note: it's antivirus, not antivir. "AntiVir" is the name of an actual antivirus software (that's also free).

Win32:Poison-DU
i have been using avast for more than year now and it never given me this issue on your torrent before.
and since using your 1.7.7 stable version since it came out, i did not had any issues with avast as well.
but all of sudden right now it is giving me this error.
and i have send the info to the avast team as well abt it

Thanks 
They probably released a bad/mistaken virus signature update today. Hopefully, the more people complain, the faster they'll fix the problem.

i hope so, since using norton and few others i found avast much better than any just like utorrent is best from others i have used previously
Offline
yea i just woke up to an avast update and a virus warning not too long ago. it sounds like avast screwed something up.
Offline
but strangely i downloaded the beta version 1.8 and it isnt giving me any more errors????
but i liked the 1.7.7 version more than the beta

I've got the same problem. Been using utorrent stable version for about two weeks, suddenly this afternoon, when it's been on all afternoon I get
27/04/2008 17:23:19 SYSTEM 1528 Sign of "Win32:Poison-DU [Trj]" has been found in "C:\Program Files\uTorrent\uTorrent.exe" file.
27/04/2008 17:23:53 SYSTEM 1528 Sign of "Win32:Poison-DU [Trj]" has been found in "C:\Program Files\uTorrent\uTorrent.exe" file.
So I let it delete the file - made sure utorrent was completely gone from my machine, went to download it again and got
27/04/2008 17:50:13 SYSTEM 1528 Sign of "Win32:Poison-DU [Trj]" has been found in "http://download.utorrent.com/1.7.7/utorrent.exe" file.
Having read the above, I then downloaded 1.8 beta and no problems.
Weird.

yes if you using avast i think the new virus update have some issues.
also download the beta version as they is no problem with it so far.
but do complaint to avast if you are using avast otherwise state your antivirus please
Offline
It's almost definitely an avast! issue only. Several users have come by the IRC channel to ask us about it as well.
Offline
ultima can you also contact avast and clear this issue with them.
i was sad and upset when i saw the virus warning
Offline
Every cloud has a silver lining. I quite like 1.8 and I wouldn't have tried it otherwise!

hey guys i was using Utorrent ver 1.7.7 and is a very good torrent software...but all of the sudden i got a trojan alert frm my Avast anti virus.....so I deleted the Utorrent and tried to download the Utorrent but again i got the same alert which was not there till today afternoon....is this bcos anti virus definations.......can someone help regarding this...
Offline
It appears it's a false positive.
Download beta 1.8 and you won't get the same message. That's what I did.
Offline
Phew! I just got the AVAST message two mins ago. Glad it's a false alarm!

Hi, I have the same problem here. To solve it while Avast people fix the error, I did the following:
Step 1
Right-click the avast! a-ball icon
Click Program settings
Click Exclusions
Click Add
Add the file, in this case c:\ProgramFiles\uTorrent\*
Click Ok
Step 2
Double-click the small avast a-ball icon next to the clock, Double -click on the standard shield icon, Click on Advanced, Click Add, and add the location of the files here too. It may be like this: c:\ProgramFiles\uTorrent.
Step 3
Double-click the small avast a-ball icon next to the clock, Double-click the Web Shield Icon, Click Exclusions, Add the URL or Web Address: http://www.utorrent.com. Click OK
That's all.

Downloaded 1.8 seems cool
Offline
Simplest solution to the problem... download the utorrent Beta 1.8, works without a hitch, and no pesky false virus alerts...
Offline
http://forum.avast.com/index.php?topic= … #msg294716
Seems like it *might* have been fixed in another signature update already.
Offline
I confirm the post of Ultima : i got the same problem and i've just downloaded the new updates from avast and removed µtorrent from my quarantine, and now everything is working just fine...
Offline
ok gr8 than i can go back to 1.7.7
didnt like the new look though 
and the grin line are too light
Offline
I like 1.8. Doesn't seem such a resource hogger either.
Offline
Hey, more people trying out 1.8, that's never bad 
Yes please please report this to Avast... I was searching for a contact form and only found support@avast.com
Did 080427-1 fix this? http://www.avast.com/eng/update_avast_4_vps.html
Edit: I think the average RAM savings between 1.8 and 1.7.7 is ~ 10%... which doesn't mean much until you load thousands of torrents http://forum.utorrent.com/viewtopic.php … 74#p289574
Offline
I don't download or upload thousands - I don't have a good enough internet connection for that - but a few times recently the other version has been running and my fans have kicked in and when I check Task Manager it's running over 50%. With 1.8 running, task manager goes no higher than 23% and then only occasionally. So that's good

The high CPU usage doesn't sound like normal behavior to me... If you want to try troubleshooting that, post in a new thread with the following pieces of information:
a) get HijackThis from trendsecure.com, run it, view the log, and post the contents in the new thread
b) get Process Explorer from sysinternals.com, run it, Ctrl+D (to show the lower DLL pane), select the µTorrent process from the list, Ctrl+S (and save the list somewhere you'll find easily -- like the Desktop), then post the contents of the saved process list in the .txt file in the new thread
Additionally, in check Start > Run > devmgmt.msc, check your primary and secondary IDE ATA/ATAPI controllers' properties to see if any of the connected devices' current transfer modes are in PIO. Post all of this in the new thread.
