For the past few days I’ve been trying to update the app via Google Play, and every time the download goes to 54% then suddenly starts installing, and after a moment I get a message that says “Error: Package file is invalid.” Then Antivirus & Security crashes.
Exactly the same problem. I tried to uninstall avast to fix the problem. Now, I find myself without it because I can’t reinstall it. The Package is Invalid issue…
Same here, HTC Desire S with Android 2.3.5. Uninstalled because I hoped a clean install would fix the error but the new install fails with the same message.
FWIW, update on Lenovo Yoga 10 with Android 4.2.2 was successful so maybe it’s related to the Android version?
I’m having the same problem. I’m not going to uninstall anything given the experiences reported above. Waiting eagerly for Avast! to come up with a fix!
Samsung Galaxy Note GT-N7000 (International Note 1) Running Android 2.3.6 (Gingerbread), Avast! Mobile Security & Antivirus 4.0.7875 definitions 150313-00, paid at €14,99 per year, so do expect action here soon by Avast!
Hi everyone,
please be patient. We have fixed version now and some users already received update via Google Play. Other will follow within a few days… I’m very sorry about inconvenience.
