|I had the same error code. I fond I still had AVG PC Tuneup installed. I uninstalled PC Tuneup with Revo Uninstaller. I could not use Revo Uninstaller to uninstall AVG because it was not installed so I used the AVG remover file http://www.avg.com/ww-en/download-t... I then rebooted. After rebooting I ran "Everything Search Program" to search for "avg" & erase any files left on my hard drive. Then I used Regseeker to search for "avg" in the registry & deleted any registry entry for "avg".|
I rebooted again & AVG installed fine.
I find AVG causes my system to run slow on my 500MB ram HP Pavilion, but turning off ID Protection & Resident Shield solved that problem. I right clicked on the components & chose ignore component state so a flag was not showing on the tray icon. Nice that you can turn these components off.
Threatfire was still loading in my startup so I uninstalled it. I also uninstalled Windows Defender. All anti-virus programs should be un-installed so there is no conflict with AVG which can slow down your PC. I use Spybot because it is the best at reporting & disabling startup entries & a good second opinion adware remover, but make sure all tweaks & teatimer are not enabled. Also do not immunize with Spybot. If you have immunized, un-imunize by clicking on undo in the immunize set-up.
I only use Revo Uninstaller for all un-installs along with Everything Search & Regseeker to completely un-install all programs & clean the registry. Works great.
Search Everything is a fantastic file finder. Finds any file on your hard drive instantly as you type without indexing. You can use wildcards, boolean logic, sort by name or folder. If you enter nothing it lists every file on you hard drive instantly.
