I have seen this topic posted here and there a few months back, but I’ve not seen any true resolution anywhere. Like many others, I experience gradual performance degradation of my Vista system when running Avast 5.0.x (currently x=545), in particular, when using the Behavior Shield. A reboot clears things up for a while, hours or even a few days, but eventually things begin to slow back down. It is most noticeable when browsing the Web (IE or Firefox) – if I disable that particular shield, performance improves drastically and instantly.
I’ve tried many reboots, deleting Avast and reinstalling fresh, etc. Ever since I’ve upgraded to version 5.0, this problem always eventually comes back. I’d prefer to have the protection of the Behavior Shield, but for now, I keep it disabled.
Experiencing the exact same here - Behavior Shield causes high degradation over time. CPU Usage goes up quite drastically, almost 100% sometimes.
Process Explorer shows “System” consuming more than 75% CPU with Behavior Shield turned on, and about 1-2% with Behavior Shield turned off, and this even without any Network Connection or Internet browsing.
Please can someone look into this, or advise if there is any clash/incorrect setting causing this. I would really prefer not to disable this Behavior Shield since I do not have any other similar security software enabled.
System Details:
Avast! Free Antivirus
Program Version: 5.0.545
Virus definitions: 100524-1
Windows XP Professional SP3
Laptop - Dell Inspiron E1705
I have the same problem with the exception that ALL explorer windows show a 5 - 15 second delay when trying to open. If I disable only behavior shield with all other shields running, all back to normal.
we found an issue that can be related to the any av5 slowdown. This slowdown may lead after few days to avast! crash too. We hope it will be fixed soon.
sorry for inconvenience.

I found this post after becoming frustrated enough to look for a solution to the problem. I’m developing a web application on my local machine using a WAMP stack and since AVAST upgrade from the “blue icon” to the “orange icon” (Sorry, i don’t keep track of version numbers anymore, but it’s version 5.xx something ), my pages started taking 500ms-1000ms longer to load! Firefox also takes much longer to start. I was reluctant to upgrade to the “new look” AVAST, but I was forced due to my registration expiring. I eventually tried to disable AVAST for a while to see what happens, and the effect was immediate and DRASTIC. I then fiddled with the configuration to see if I could isolate the problem and sure enough found that the Behavior Shield was too blame. Disabling Behavior Shield fixes my problem instantly. So, I would imagine there’s still some bugs to fix in the new version and hope too see something soon (Specially if you have millions of users!) An advisory on what to do about the problem and whether it’s safe to disable this feature would also be welcome. (Ok, so I checked… it’s ver. 5.0.545 )
So, which is it? Behavior Shield or Screensaver? And will it be fixed soon?
I noticed slowdowns on my system too (3.4ghz P4, 2gb RAM, 80gb 7200rpm 8mb hard drive, XP Home SP3/IE8 with all updates) after the computer had been up & running all day. A reboot would solve the immediate problem. Will Alwil solve the larger problem? Soon? -kd5-
Since I found this thread on Page 2 with no subsequent replies, I have to assume that no one of any import has either read this or cares to acknowledge this legitimate concern, or can give us any idea whether or not this issue will be addressed any time soon?
I really don’t want to cripple Avast, I would probably be more inclined to go back to v4.8 until all the bugs get worked out of v5. -kd5-
I guess now you need to know that your kduncan5 (at) hotmail.com is available to all spammers and scammers.

First, I don’t care who harvests that email address because I don’t use it anymore, haven’t been there in YEARS!
Second, I’ll say whatever I want to say in my signature! ‘Getting old ain’t for sissys’ refers to all the aches & pains you’ll accumulate when you get MY AGE, not what you have chosen to read into it! Besides, if you’d bothered to look above my last post, you would see that I’ve already outlined the pertinent aspects of my computer!
Third, why should what country I live in matter to anyone besides someone who chooses to make such a big deal out of it for no good reason as you have chosen to do?
So, I ask again: How does your post help ANYTHING???
I have asked a question. Obviously you’re not capable of answering that question so why did you even bother to post in response to it? Just because you have 4929 posts here and I only have 21, do you think that gives you the right to crap on my post? -kd5-
