hi C1t,

Ever download a prior version of avast! as a trial version in the past and allow the trial license to expire? Use of cracked copies can do that too.

You can get the official versions of avast! from here: http://www.avast.com/download-software

Use aswclear.exe to remove any prior versions of avast! left-over from prior use: http://www.avast.com/en-us/uninstall-utility Reboot after use of aswclear.exe.
