I had avast! running on my previous Ubuntu machine, but due to an error (not caused by avast!), I had to reset it and reinstall Ubuntu alongside Windows 7. I then shutdown my machine. The next day when I tried to open avast!, it loaded on the dock for 5 seconds and then all of the sudden it stopped loading. When I checked my installed programs list, it wasn't there. I have tried rebooting my machine, and I have tried to reinstall avast! but I keep getting the same result. Does anybody know how I could fix this issue?
