update fails & shows general error

Hi there , im not sure how useful this will be , im just sharing my own experience today . i started off by having the annoying avg needs you to restart to finish updating issue , which i attempted to fix by uninstalling and then going to reinstall . unfortunately the attempt to reinstall kept failing , and after exhausting answers in this forum and the old one , i decided to try reinstalling avast , to secure my computer . well when i tried to reinstall avast , it had a hissy fit and said i didnt have base filtering engine running . so i had a look for that problem , ended up at sevenforums at this thread http://www.sevenforums.com/system-security/206716-how-turn-base-filtering-engine.html , and on it found this link to a widget http://download.bleepingcomputer.com/sUBs/MiniFixes/RestoreBFE.exe which said it had restarted the engine . i then retried installing the trial version of avg , ( one of the version i had tried to get going ) the reinstall failed as it said it didnt have admin priveleges , so i re ran it telling it to run as administrator ,and the install finally worked . now to the best of my knowledge the only things i had deleted or played with today was the update files for avg which one of the tips on the avg forums said to delete and try and get the update to fix itself , but for whatever reason , that so far seems to have got avg back up and running , however , if the guys putting out the latest updates cant come up with some fixes , it will put ordinary users offside if there isnt easy fixes to issues . so far about this one issue , i can only see this 1 question , on the older site there were lots . so has it generally been fixed or is it still being followed up ?
