I’m interested is there any way that someone can be sure that have “clean” Avast (without being modified by virus)? I asked that because I don’t know why sometimes Zone Alarm ask me to permit Avast files to go the Internet but I already gave permission for that. Is that happen after updating or why it happen? Microsoft has one file called File Checksum Integrity Verifier to check if the file is original. Can Avast be checked, too? I downloaded Home edition from avast.com and I register it. Is there some file checksum number that show that avast files are original?
Well known problem of Zone Alarm and the file avast.setup used for updating…
It’s a temporary file used to update. Zone Alarm is detecting it as changing but it only ‘changes’ when a new version of avast is present.
If you search the board for a little more information you’ll get it…
Thanks for answering. I saw earlier posts. However, Zone Alarm asked to permit again other Avast files, too, not just avast.setup for example programs for web scanner, email scanner…Is that suspicious? Can it be because IP address for connecting may be different (also avast destination site). Beside Avast I use AVG and I didn’t get virus alert.
Are there some available checksum numbers for avast files. I made a a checksum test with MS fciv.exe.
If there is a program update on your system, not.
Otherwise, it could be a ZA trouble more than suspicious…
Maybe for the avast.setup but not for the others.
Do you use two antivirus in the same system at the same time? Both with residents active?
Yes, I use Avast and AVG at the same time. However, now I closed the AVG Control Center so I guess that it means that it closed the resident AVG scanning, too. Why is it a problem? I know that some AV combination can make a problem but I didn’t have with these two AV. Is it enough that I use only Avast?
Avast features self-checking of its EXE files. All avast EXE files are digitally signed and the signature is verified whenever the file is executed.
If you want, you can test it - try modifying an EXE file from the avast folder (e.g. ashQuick.exe) and executing it (or maybe not :)).
And yes, it’s perfectly normal that all these modules “change” on program update. So your firewall will keep bugging you after each (programmatic - but fortunately not virus DB only) update.

I think it’s not enough. You should disable the providers and not only closing the Control Center, but maybe I’m wrong. I’m not an expert on AVG.
