Hello!
Cant boot into my XP this morning…
When i try to boot into safemode it stops on aswRvrt.sys.
I read some posts about it and here is FRST.txt what I made, but I dont use “OTLPENet.exe”, I use my own LiveCD.
Now I am afraid what it can happen on all our company computers… Because it is second time then I get with this problem… Last time I reinstall OS, because it was my home computer, but if it starts happen with business versions of avast, I cant reinstall all company computers… :-\
Since you are using a business edition, did you deploy avast to the client through the console ?
Thanks for quick replay 
No we install avast clients locally, but use console created package…
Initially we will try a system restore
Download the attached Fixlist.txt to the same location (USB) as FRST
Start FRST and press fix
On completion try a normal boot
About hour ago I try again “Last known good configuration”, and in this time it works… In morning that dont work… But I afraid what that will happen again then I restart PC, then i will try your method with that fixit.txt, thanks so far!
