not w32 compatable

[KG]

I suddenly lost my virus program...Nod32....and couldn't get it to startup
again. Removed it completely and installed Avast as a trial and now I get
"not w32 compatable" message and if I try and open any part of it via
explorer it just freezes and will not turn off via the Cnrt/Alt/Del command.
Everything turns to custard and I have to reboot.
Suggested That I had the w32 bagle worm but got a program called
'fxbeagle.exe' down and ran that and it said it was not there.
So now using the computer with no virus protection....any help please. This
"not a w32 compatable" message seem to be the problem

That error message is not correct...it is " not a valid w32 application"
sorry about that

I've seen this when the download is from a "questionable" web site or the
download was with problems. Try downloading it again.

NOTE: Avast offers a "free" 14 month license for their Home version of their
software. You can request an activation key via their web site. However, this
is for personal use.
