Simple Interface does not appear when starting Avast, cannot scan

I went away from Avast about 6 months ago as I was having problems, have been using AVG since then but am now returning to the fold. However I cannot actually get the Simple Interface to show on the screen. The short splash screen runs showing memory test etc, then a blank screen with the command line in the task more showing “simple interface”. Just the normal desktop. Any ideas? The update programs work but I cannot start a manual scan.

Operating system? Any other security programs running? Was avg completely removed?

This may just be a corrupted install. A uninstall/reinstall may be needed. You could try a repair via add/remove programs.

What problem where you having before?

Is there anything in the avast log viewer, (right click the avast icon), Error or Warning sections, related to or about the time this happens ?

Thanks for responding, the OS is XP with SP2 and there were no errors in the log, but the suggestion of a complete uninstall/reinstall seems to have worked. I have the right screen now.

No problem welcome back to avast!

Glad the your problem is now resolved.
