May be it is good to do defrag of disk?
This will speed up disk reading and minimizing time for avast to scan files on start.
Mr.Babis, I am computer technician by profession and I do fix computers for living. Defragmenting of disks is so crucial, that there is no chance to forget to do it...
I repeat, once avast! is uninstalled, everything goes back to normal...
EDIT: Absolutely nothing is wrong with booting untill ashServ.exe kicks in...
So, right now starting of Windows after logging in, takes around one minute... and it was always just few seconds...
