Avast just auto-updated itself to 2214. Emails still blocked, and now I can't manually virus-scan files via the context menu either (Avast window is blank). Have had this software for years without any issues, but lately there have been... maybe time to look for other software?
If your context scan is blank, that means your avast install is corrupt.
You need to perform a clean install:
Note: It's important you used the stub online installer from the one I linked.. NOT the offline one.
Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn't)
1.Download your version of avast! and the avastclear tool:
Avast Free AntivirusAvast Pro AntivirusAvast Internet SecurityAvast PremierDownload
Avast Clear Tool2. Uninstall Avast by control panel [If you don't have Avast in control Panel go to #3]
3. Uninstall in safe mode using Avastclear. [Running Avastclear is normal mode will give a prompt to go into Safe Mode]
Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle.. if so, uninstall it and reboot.
5. Install the version you downloaded.
6. Reboot.
Free: If you have the Free version, register the product for free for a year from the avast! UI.
Paid: If you have a paid license, insert the license key/activation code after the reboot at stage 6.
If you have any questions, please don't hesitate to ask. It's better to ask than make a mistake and start over again with the process.
