Well, I was writing when Pavel (from Avast Team) answered. Good he did
. I'm leaving what I already wrote anyway (after all, I took the time to write it
).
*** start of useless post ***
Since Avast Team is intensively working in Avast 7 beta, It may take some time to until this is answered in some way.
Maybe some Win2k user will have the possibility to answer
.
In the mean time, maybe you should try to attach some screenshot.
Alternatively, may I ask, which other security tools you have (or used to have) installed? Specially (but not only), which other antivirus you had before avast? Have you uninstalled it? Have you removed the respective potential remnants using the specific removal utility for that security tool?
You could also try to run
http://www.avast.com/uninstall-utility under
Windows Safe Mode, for each and every version of avast you ever had installed or updated to. Than download again ANEW avast Free (or Pro Trial or AIS Trial) from the official web site only and try again the install. BTW, the downloads from avast should contain a valid digital signature (certificate) if it is downloaded correctly.
Please report back.
