Hi,
I've recently updated to the lastest version of avast, 6.0.1203 / 110709-01. I'm now having problems playing left 4 dead 2. Every so often (after no more than a few seconds, the game freezes. Disabling avast seems to fix the problem.
Am considering downgrading to the previous program version as a short term workaround.
Please investigate.
Thanks.

Plus when you press E (use) PC beginning to slow, and drops to 10 fps!

I have just tried mine and it works fine, however It was not installed (i had to install it, due to re format a month ago) so either try delete local files then re install it. Or maybe add the exe + steam over lay to exclusions.
I have had a couple of slowdowns on other games due to the auto safe zone stopping the part of a program after it has launched (so you cannot see the window, either alt tab and run normally. Or turn auto safe zone off.
-
seems to be no more problems

what did you do to fix antrox?

absolutely nothing, no settings, no install or remove

left 4 dead 2 is a streaming program.
Occasionally streaming programs generate false positives.
That is my guess at what happened here.
A false positive generated by one the streams.

That what its explain all... Wondering why those things does make avast! to appear to act like this ? Is it because of the business that made the game or its generally based on microsoft that the OS is made like that ?
Just curious sorry but i want to know why...
-
I don't know the reason for this. I do know that Avira users have experienced the same FP problem with Steaming Programs.
If I were to guess I would say that the False Positives generated in Streaming Programs are due to the how the program handles "Event Processing". Whether the software in question has integrated CEP or not. That would be my take on it, though it is more of guess than anything else. :) so please don't quote me on this. ;D

Ok its wasnt needed but thank i wont quote you dont worry.

I'm still having this problem. After Avast's program updated the other day, trying to launch Left4Dead 2 would present me with a screen saying "Completing Installation... 1%" - despite the fact I've had the game installed for over a year and a half.
After hanging on that screen for several minutes, it would eventually error out with "incomplete installation". Looking up the problem on Steam's knowledge base, they mentioned McAfee caused conflicts, so I selected to turn Avast's shields off for ten minutes and the "Incomplete Installation" problem went away.
Ten minutes later, when Avast turned itself back on, I was in the middle of a Left4Dead match with my friends and suffered horrible bouts of stuttering - the game would often lock up for minutes at a time. Alt-tab, turn Avast off, stuttering vanishes.
The problem is, doing this requires leaving my entire system insecure. On top of that, me and my friends play LOTS of Left4Dead, and it's a fairly big group of friends at that, so when the call goes out that we're playing, it's often a game of musical chairs as to who gets in. Taking that extra moment to disable Avast every time I get an invite has already cost me my spot more than once since this started happening.
So either I turn Avast off forever (and then what's the point in having it installed at all?) or... well, I guess there is no other option, is there?
-
Or you could roll back to the previous version as I did, see filehippo.com. As long as you keep the definitions updated, but don't update the program itself I would imagine you should be fairly safe.
Failing that I tried disabling avast entirely and using MSE instead, but decided there was less risk in simply rolling back one version of avast.
-
Interesting, i never had any problems with L4D1 or L4D2 when using avast!.
-
Me either, until now! And actually L4D1 is still fine.
-
slow down in L4D2 is back today! 100% Avast fault, because help turn off all screens. I didnt understand
-
I'm having the exact same performance issues, but with Civilization 5. Starting the game takes much longer than normal, loading a saved game takes upwards of 15 minutes (versus about 1 min. before), and the game hangs for 30 seconds at a time. If I disable Avast everything runs smoothly. This only started happening when I moved to Avast 6.
-
Since updating to Avast 6.0.1203, the only way I can play Left 4 Dead 2 is if I turn my Avast protection off. Prior to this update, Left 4 Dead 2 was working fine.
Upon launching Left 4 Dead 2, I would get stuck at a "Completing installation... 1%" message until an "Incomplete Installation (#)" error would appear. The only way I could get passed the installation % message and launch the game was to disable Avast. Since the initial disabling of Avast, I no longer receive the "Completing installation... 1%" message or the "Incomplete Installation (#)" error.
While Playing With Avast On, Left 4 Dead 2 would immediately freeze upon load of a game mode and sound would get stuck in an infinite loop.
While Playing With Avast Off, Left 4 Dead 2 would run fine.
Although turning Avast off is an option, I really would prefer to have my Avast protection on while playing the game.
There are other people who also have this problem. Here is a link.

Can someone please try to fix this problem?
Thanks in advance.
OS:
Windows XP SP3

It's not only for Left For Dead 2.
I have this issue for all my games on Steam.
I have to deactivate Avast to "complete the installation" (like sandbox' post) or to play a multiplayer game (like DawnOfWar Retribution). There are no errors, no popup to warn me about that : games are just freeze.
A temporary solution would be to cancel the installation of the update and come back to another, but this option is not implemented by Avast. (an idea to develop?)
Need a quick fix!
OS: winXP service pack 3

Yes, this update messed up my online gaming through Steam. I disabled Avast from the menu for 10 minutes during the game and it started working and after 10 minutes when Avast powered up the game stopped working. I'm switching to another program since this update was broken.
-
I'm having the same problem with Left 4 Dead 2 freezing when I try to pick up something and going into sound loop while frozen. When avast is turned off it runs fine. Like most users here I rather not turn it off. What can be done to fix this while having avast on and without rolling back after this update?

Hi
The trick is finding which part of Avast! is the trouble. Do this by disabling specific shields one at a time, rather than just disabling all protection. If Steam uses http (not sure how Steam works), I would start with the Web Shield. Just remember to re-enable them when you are finished.
-
Does anyone know how to locate previous version(6.0.1125) for rollback install ?
I looked on filehippo but only saw latest version. I saw some other places after searching(http://dsaloka.blogspot.com/2011/05/avast-internet-security-601125-2011.html ) but I am suspicious that these are cracked versions.
I don't like option of disabling virus protection I paid for so I can play games I paid for...
-

Better you try my above suggestion, but if it comes to that, Filehippo does have the back versions, they are along the right sidebar.
-
I found the same link at (http://www.filehippo.com/download_avast_antivirus/ ) but need to install
the Internet Security version that includes Firewall and Anti-spam. Will my license key enable Firewall and Anti-Spam if I download the version at the link ?
-
Oh, inserting the key into free versions upgrades them to paid, if I remember correctly. But it might also upgrade you to latest version.
No one has suggested reinstalling yet, so I suggest that in addition to what I mentioned earlier. There are plenty of people here with the problem, but a couple popped in and said they had no problems at all, so if this happened to all of you after a program update, perhaps something went amiss with your update process. Try reinstalling Avast!.
-
These four Avast shields appear to be causing the problem:
1. File System Shield
2. Mail Shield
3. P2P Shield
4. IM Shield
For the game to be playable, you cannot have any of these shields enabled. If any of these shields are enabled, the game will freeze and get caught in an infinite sound loop.
It doesn't matter what the heuristics settings of each shield are set to either. Even if you lower the heuristics settings of the shields, the game will remain unplayable.
-
I've got the same performance issue with version 6, now i'm rolling back to 5.0 hoping everything will be fine, please solve this problem as it happens to a lot of users
-
I am getting the same problem... i nearly gave up trying to update l4d2 coz it would always fail... untill i came across a forum about Avast 6 stopping L4d2 from updating...
then found out you have to disable Avast or in game if you press "TAB" or "E" the game would freeze!
Please Avast sort this out as i dont feel safe playing L4D2 with Avast off! :-\
-
I have same problem...
-
I hope the Avast! team can iron this out with steam/valve soon. It's quite an inconvenience and threat as well when you want to play your game. OS: Windows XP SP3
-
Just to add some confusion to the pile, my L4D2 runs fine, without any such pausing, including when "using" with the E key. Hooray for the problem being harder to track down.
I'm using Windows 7 x64.

I'm using Windows 7 x64.
Thank you for being one of the few who actually left some relevant information.

I am also on windows 7 64 bit with no issues, if it helps.
-
Windows XP Home SP3, and I have the problem.
-
Well, so far, out of the very slim majority (not nearly enough for anything definitive) that posted their OS, XP is affected, 7 is not.
If you already posted here and are still monitoring this, posting your OS certainly helps narrow thing down.
You don't necessarily have to make a new post, you can just edit your original one to include the info.
-
mine spec is windows xp 32bit (sp3)
previously i used version 6 which cause the freezing issue with lfd2
now i went back to ver5 (the last ver 5) the problem seems gone, the game still lags at some point for a little while but totally palyble(not sure if that caused by avast as well)
-
so,any idea how to fix this?
-
Also running XP SP3. I had to roll back to old version I had backed-up as file hippo did not Internet Security version. I can still get get latest virus updates so I can wait this out. I recall this happening once before and it was addressed in a few days. This was back when Left for Dead 2 was new.
Are there are debug flags or ways to log what Avast is seeing to help figure this one out ?
-
I'm yet another L4D2 player running Windows XP (SP3) 32-bit, and this issue has gotten me extremely frustrated. I really love Avast, and the last thing I want to do is disable it to play the game, because it just seems far too risky. I've tried every other fix for this problem, and so far, nothing has worked.
I sincerely hope that Avast/Steam gets this problem figured out - hell, I BEG you: It's irritating beyond words, and I really don't want to have to give up on Avast entirely...
-
Perhaps this is not a solution either, and is somewhat potentially risky, but has anyone tried adding the Left 4 Dead 2 game folders to avast!'s File System Shield Exclusions list? (See attached image.)
The computer will still be protected against threats, it just won't be directly scanning any Left 4 Dead 2 files or folders. If a threat did happen to come along, it would still most likely be picked up by another avast! Real-Time Shield. Again, as previously stated, I must stress that this is a little bit risky.
There has been mention of more Real-Time Shields than just the avast! File System Shield causing problems, so maybe this won't work. However, I reckon it's worth a try.
-
I have tried adding Left4Dead 2's folders to the exclusion list, and the problem still persists.
-
Has the latest Steam Left for Dead 2 Update made any difference ? (I rolled back to previous version I had backed up). I think they just added Dead Air version but sometimes they add in little tweaks.
Also, does playing in offline mode make any difference ? I noticed that I only get stuttering when I interact with object such as grabbing a weapon or opening a door.
-
The latest update to L4D2 (for me anyways) hasn't fixed/changed the problem for me personally, and the stuttering happens in offline mode as well. I've updated my drivers and such, and tried pretty much every solution out there.
It's really frustrating when you have a computer able to perform well, and something out of your control is messing up your game. I'm going to try including the L4D2 folders in the shield exclusions, but I'm not getting my hopes up at this point.
It seems like the stuttering happens mostly at hordes and event triggers.
-
Hi, I pay for Avast and it stops me playing Left 4 Dead 2 while maintaining the latest security.
I'm on WinXP SP3.
With Avast version 6.0.1000 Left 4 Dead 2 installs and plays fine.
When I update the program I get the install problems mentioned above and the game play stuttering mentioned above.

Just a thought here, does l4d2 use any other folders beside the default install one ? Like for saved games ? I had incredible stuttering when playing Bad Company 2 when i first joined a server, it turns out the game keeps changing some files in the "my documents\bfbc2" folder and after i added that folder to avast! exclusions, no more stutters. Not sure how l4d2 works but perhaps it is also creating or modifying files during gameplay and avast! is constantly scanning those in the background.
-
Left4Dead 2 has no such thing as "save games". You play an entire campaign in one sitting or you quit and restart from the last map you were on (but given that an entire L4D2 campaign can be finished in 45-60 minutes, it's not a big deal).
Nothing else to my knowledge is stored outside of the Left4Dead 2 install folder. All custom maps and whatnot goes in there and not to a folder somewhere else on the HDD.
-
Like i said i don't know how l4d2 works, it was worth a shot. I reported this thread to the mods though, i hope they will look into this issue.
-
Had the same issue (win xp sp3 x86). Game work fine if I turn off 3 shields: "System file shield", "P2P shield" and "IM shield". Other shields can run and game work fine. + I don't need to turn off all my shields but this problem is annoying.
-
I tried adding all the game folders to the exclusions, and no dice. I had changed a lot of settings to reduce the stuttering, but suddenly this morning, it's become worse than ever! I do hope this situation gets resolved, because avast! is the preferred AV of choice for a lot of gamers, including myself, and I refuse to ever use a different AV program (nothing else compares!).
-
hello, I have the same trouble with the last AVAST 6.0.1203
All Steam APP won't works perfectly.
It's necessary to stop the File scan in Avast to play with Portal 2 or Left4Dead 2
I have a lot of acces in my Raid 0 HDD on win XP Sp3 X86
-
I guess I'm just going to roll back to Avast 5 until this situation is fixed. I really hope they have someone working on this...
-
Well I am using Win 7 and lol today I just installed L4D1...
When I started playing the way the game was being displayed was strange...
The graphic was not playing smoothly etc...
Do you guys think it is related to avast?
Well don't blame me for not disabling the avast shields and try again because I uninstalled the game immediately after seeing such a bad display of that game...
-
Since rolling back to avast 5, I have literally had absolutely no problems with my games. They run as smoothly as ever now, so it's absolutely the latest avast that was causing the problems.
I really hope they are fixing this, as I don't like opening up my comp to any vulnerabilities, including not having the option to block out whatever websites I enter in to block.
Please tell me the solution is forthcoming!

I registered on these forums specifically to post in this thread checking to see if there was anything in these forums about this issue (the incomplete installation (55) issue). I'm experiencing it with Deus Ex: Human Revolution, which just unlocked this morning, which is to say that it tried to unlock, but Avast somehow blocked it without any of its scanners showing anything suspicious. It sat on 1% for several seconds before declaring an incomplete installation (55).
I ended up disabling avast, which allowed it to unlock, and then it unlocked (I didn't try disabling avast while I was playing, so I don't know if it would have run faster without it). About a half hour ago, I closed the game, and it tried to install a patch (Avast was active). It downloaded it, but failed to install, with the same problem as before. Since the patch didn't work I've tried to make it work without disabling avast, but without much luck. I've had to disable the file shield, P2P shield, and IM shield, and trying to let steam patch it without disabling the file shield was impossible, even with an exclusion on the steam folder (H:\Program Files\Steam\*) in the file shield's expert settings -> exclusions (with r/w/x all checked). However I noted using AnVir task manager that Steam appeared to be running a DLL file which was not named with a .dll extension (~26.tmp) from my Documents and Settings\[username]\Local Settings\Temp folder. It exports one function, _runfunc@20, and imports a lot of functions, which doesn't give me any idea what it's about. Putting an exclusion on that file specifically wouldn't be possible if it's recreated whenever steam is run (why are they doing that, anyways?), and an exclusion on the temp folder would be downright dangerous.
Another thing. Approximately 80% of the games I've gotten from Steam in the past several months (including from the Humble Indie Bundle 3, quite a few) were thrown by Avast into the autosandbox automatically, until I went looking for the setting to make it stop doing that automatically, and I've seen some annoying false positives which were never addressed before too (such as seeing a program which came with HP computers and was a vital part of the automatic system restore software, be classified by Avast as a 'potentially unwanted program', and as such automatically getting thrown into the virus chest).
P.S. I'm using Windows XP Home SP3 and Avast 6.0.1203.
-
I have two systems I play games on, one which will be retired from game duty soon running Windows XP 32-bit and a new one running Windows 7 64-bit.
L4D2 is unplayable while Avast shields are active on Windows XP-32 but works normally on Windows 7-64.

Thanks DavidR for the help.
Thanks Avast for addressing the problem.
-
You're welcome.
Thanks for the feedback.
-
That problem might be resolved soon for all users after that release come live.
I got steam games too and i dont play too much so i wait before to upgrade my steam lol.
Im happy that avast! resolved it.
-
Yep more users will then be able to use avast :)
Well next time I'll try to get Left 4 Dead 2 and test it if it is working properly...
-
I guess avast! is the most used antivirus in steam so im glad they fixed it fast. ;D
-
Still having this issue. Hoping the beta goes live soon.
-
Guys/girls, it's fixed! Just update your avast within the avast program itself, no beta needed. Thanks avast team. Game plays so much smoother now too.
-
thx for fix! ;) now games working good again! :D

......I've been using Avast with Steam for years. It's only been in the last few months that Steam started having issues with Avast.
......I know Avast had a program update sometime in the last few weeks. But I was still having the same problem even after the update.
The first problem that I encountered was this:
......Steam would start but the game that I selected would not start. I found out that the game was updating but there was nothing to indicate that that was what was happening. The usual update box and progress bar did not pop up, but I could see the update progress on the steam page.
......At this point I only had to turn off Avast real-time shields until the update was over and then the game would start and run normally.
But eventually the problem got worse.
......Left 4 Dead 2 wouldn't start or would load very slowly. Once in-game the screen would lock up for 10-30 seconds at a time at similar intervals.
......Killing Floor loaded very slowly, and glitched with poor frame rates and intermittent slow downs.
I swept my machine for viruses and root-kits.
I checked my video card and RAM for errors.
I reinstalled steam and my steam games.
I completely uninstalled and reinstalled Avast.
I tried shutting down one Avast shield and then another and so on.
I added the steam folder to the File shield exclusions as I noted below.
I set the heuristics settings in all shields to the lowest settings.
Nothing worked. I had to shut down all Avast real-time shields to play without the lock-ups.
......I was still having the same problems after the update but I decided to try again since there was an update. I went thru the shields again and put exclusions in wherever I could and it seems to have worked.
......I have listed my Avast settings and exclusions below. I hope it helps.
......If you're wondering about a setting that I have not noted here, it's set to default on my machine.
......I have not tried these exclusions one at a time or in any other combination to see if only one or two will do the trick.
