I had the Advanced System Care on here for a bit along with the free edition of AVG a couple of years back and never had any real problems. But the mesh even in compatibiliy mode of all the programs conbined isn't good.
This is one reason I went with a newer program(VIPRE Internet Security 2012 presently on) someone recommended and found it covers more then several combined! The ASC program wasn't even on the retail 7 but had been on Vista along with AVG at the time and later while running the 7 beta builds.
If the log from the scan was seen before you used the recovery option it wouldn't matter now since AVG was pointing at a corrupted file. If still seeing the same the recovery may not have been as full leaving the driver
file needing replacement if other problems are appearing.
Between a run of the System File Checker using the sfc /scannow command at the Start>Run command line while having the 7 disk in the drive and even booting live for the Repair tools to run the Startup repair tool may see the file replaced for you if you are running into start up problems.
