Regcure has found over 3000 problems so far, and it's still going
Do I actually have that many reg problems? My boot time is less than 15 seconds going into Ubuntu, and ~30 seconds for Vista, and it says that's the major effect these bad reg entries have
E: Holy mother of pineapples Batman, over 4000 problems at the moment
E2: 5000, what the hell?
E3: Woot, 6000, come on 7!
E4: We have 7 Will it make it to 8,000?
E5: Of course it will Is this thing ever going to end
E6: Umm, guys, it's at 16,000 and has no intention of stopping...Is this thing wiping my entire registry or something
E7: 20,000...Wahay!
E8: Approaching 30,000...I didn't think the registry even had this many files :S
Screw this, it's at 40,000. To hell with it, I'm getting a proper registry cleaner
Using RegSeeker now, much easier on the eye, told me it was scanning all my HDDs, and now it's scanning the registry, with a delightful little progress bar. And at 40%, it has 974 entries, almost all of which are "unused" file extensions
On top of that, it has a nice shiny "Backup" button which was sorely missing from Regcure...
To OP, I would spend the time finding out what is wrong with AVG. If its fooked something more serious might be up with your system. If you are on pista try a system roll back to before you removed AVG if possible.
