As there is no known Android virus, why uninstall that today? (do they have Avast for android?)
Also, I'd seen that when a video file is corrupt. Be sure to remove all the files from the card and start with a fresh format. Then add half the files. If it works the file it locked up on is on the other half.
My partner has a Samsung Galaxy Tab GT P1010. She switched it on earlier and it went into the normal media scan which scans both the internal memory and the SD card for media files. For some reason, the media scan is not scanning the SD card, and remains at 0%. She left it to run for several hours to see if this would fix the problem and it hasn't helped.
We have done the following:
1) We have reset the tablet several times with a hour between the power on and the power off.
2) We have removed the SD card and started the device - which allowed the tablet to scan the internal memory and start up as normal.
3) I did some research and found a post on another website which suggested installing Avast antivirus which has been run with and without the SD card installed and it only found 1 Trojan which has been removed, and unfortunately this has not resolved the issue.
My partner has told me that she has installed a new game today, but we are not sure that this would be the issue. So can anyone provide me with any advice on what to try? next as my partner likes the new game that she has installed and doesn't really want to loose it if she doesn't have to.
