installed avast pro 4.8 demo it won’t go on win vista. cant delete using controle panel-remove\change " there was an error during instalation".at start up it scan the memory <open up the skin and thats it. when trying to start it usint windows starter it sayes “unknown error-program can not activate resident part (Standard Shield provider not found)” what to do and how to remove ths antivirus off my comp?
Well a failed install could be down to having another AV installed (a common cause of a failed install), as avast works well in Vista to my knowledge.
Have or did you another AV installed in this system, if so what was it and how did you get rid of it ?
Download the avast! Uninstall Utility, find it here and save it to your HDD.
-
Now uninstall (using add remove programs, if you can’t do that start from the next step), reboot.
-
run the avast! Uninstall Utility, reboot. If step 1 failed (yours did) it may be necessary to run this from safe mode, once complete reboot into normal mode.
2a If you still want to try avast and had another AV installed now would be the time to uninstall it and reboot.
- install the latest version, reboot.
