I recently had a malware infection. A trojan, Avast network shield block it from reaching its destination url but could not find and remove it. I had to install various other scanners to find it and kill it. I have since removed those items so I am back to 1 av.
Since then the tray icon for avast has not started up with the pc. The main service has but not the avastui.exe. This is only an annoyance but I’d like to try to fix it.
I’m running the latest version on a fully updated windows vista laptop.
Goto Control panel and select avast! antivirus. Click Uninstall/Change and select repair. Let the installer run unhindered. Reboot and see if it is fixed.
