FWIW, the incompatibility exists between PD11/12 and Avast 6.0.1203 in XP SP3, Vista SP2, AND Windows7 SP1 (I’ve tried them all with various OS and hardware configs.)
No problem at all with previous version of Avast program.
Hi folks,
I suspect the problems with PerfectDisk are the same as those a number of us are facing with Retrospect 6.x / 7.x and Ghost 12 - I’d encourage those of you seeing this to try something like what I did, described here:
http://forum.avast.com/index.php?topic=81135.msg666107#msg666107
…to see if you can confirm what’s going on - if it’s one problem that’s breaking all of these products, one hopes it will be more likely to catch the development team’s attention…

All the latest news for PerfectDisk (PD) related issues - there’re two known problems:
a) boot-time defrag isn’t working (error 32): this is caused by firewall component (AIS only), we issued several file system requests which cause PD to fail defrag initialization. They have to fix it in their software, but we found a workaround for our users.
b) XP machines are slow with PD, app startup takes several minutes: the problem was in file-system shield (Free/Pro/IS)
[b]Those who use avast build 1203 they can patch avast! right now (only for advanced users) - don’t wait for next program update:

Is this just going to fix PD issues, or will this address other similar faults e.g. with Norton Ghost?
it seems so (according to description of the problem in the first post: http://forum.avast.com/index.php?topic=81135.msg663273#msg663273)
i updated that web page, thanks for info
This patch has ABSOLUTELY no effect for me on XP, Vista, or Windows7.
No versions of the patched files existed on any my machines prior to applying the patch.
The ‘revised’ patch did the trick.
All is right with the world.
I tried to install the patch, but avast fails to start afterwards.
The system event log reads:
`Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7000Description:
The avast! Standard Shield Support service failed to start due to the following error:
The specified driver is invalid. `
I had to revert back to the old drivers in safe mode 
I’ve got avast 6.0.1203 professional.
@Herrminator, yesterday I updated patches, it should work now.
I’ll have to go now. I will test in the night, when I’m back.
Thanks for your quick replies 
!
Finally, I found the time to test the patches.
Everything seems to work fine now!
Thank you!
Thanks for the feedback…!
After adding a new MS “Wheel mouse Optical 1.1a” to my system along with Intellipoint drivers I rebooted. As the system booted up I noticed it was taking longer than usual and the hard drive really seemed to be working harder than it should have. Oddly enough my first reaction was to check for excessive fragmentation using PerfectDisk 11. I attempted to start PD11, and the grinding from the hard drive started again, and then entire system became sluggish and less responsive. A good 5 minutes or more later, PD11 finally started up, but responsiveness still seemed a bit off.
I’ve been sitting here uninstalling the intellipoint software and trying the system without it…removing and reinstalling PD11, reinstalling the intellipoint drivers…nothing seeming to help the problem. Then, I’m not sure why, I decided to disable Avast shields and see what happens. BOOM, PD11 pops right up in no time. No horrible strained grinding from the hard drive, no delay.
So the mouse and it’s drivers had nothing to do with the scenario, they just happened to be things that I knew for sure changed just before I noticed the drastic performance drop. What I think happened is the system had updated to the latest Avast program version, but had not yet been restarted until after adding the mouse. With the latest Avast now loaded, startup was slow because PD11 loads its services and agents and what not at boot time.
Having found the apparent conflict (between Avast and PD11), I did a google search and found this forum that seems to confirm my suspicion that Avast and PD11 are not longer playing nicely together. I thought I should comment since it seems that people are still trying to narrow it down to what versions and what OS this is an issue on.
Windows XP Pro 32 bit, SP3 (Up to date)
Perfect Disk 11 (build 185)
Avast Free AV 6.0.1203 (Definitions 110809-1)
If forced to make a choice between the two at this point, naturally I’d be more concerned about malware infections than fragmentation. On the other hand, if the AV software is going to render my system slow, unresponsive, and unreliable under certain conditions, the extent of which is still unknown, then the AV software is causing just about as much grief as as some malware might.
I think my solution is going to be to keep Avast disabled until a new program version is released. I might even revert back to AVG in the meantime so I don’t feel totally unprotected. I’m a big Avast fan and not so much an AVG fan as of late, so I really hope that this problem gets the attention is deserves so I and many others can get back to using it along with whatever other software they might like to use.
Not needed, apply the second patch: http://public.avast.com/~kurtin/patches/
