Server issues.

hey guys i am currently working on a 08 SBS machine…
this is the exchange server for a company, i rolled out Avast! using the ADMN last week, net client to the machines and Net server to the server.

this has caused a few issues.
after first reboot for the server Store.exe never started and the Microsoft exchange information store service is failing to start also…
on instruction i removed Avast! net server, this solved my problems.
but without anti virus i updated the exchange to SP2 then reinstalled Avast net server. (i read on a forum this helps)
Still this has not helped i got into the office this morning and the exchange was down.
any help would be greatly appreciated.

I had issues with out IMAP / SMTP mail – disabling ‘Web Mail’ fixed it.
