The problem is not Avast anymore, I know that because it has being installed. But Avast made that problem when I installed it, so whatever happened during this process I need to fix it. AVG and Mcafee should not have anything to do with this since I had both running at the same time before with no problems
An understandable, yet incorrect take on this issue.
Avast didn't make the problem. You did by having more than one AV installed. The installation of Avast maybe brought it to a head, but something like this was always going to happen, sooner or later.
- Save the full installer file of whatever AV you want to use on your hard drive.
- Download the uninstall/removal tools mentioned earlier in the thread, for McAfee and AVG.
- Go offline. Disconnect completely.
- Uninstall both AV's (one at a time) from the control panel.
- Run each uninstaller in turn.
- Run a new install of the AV of your choice, follow the various prompts.
- Check the Windows (or any other) firewall is turned on.
- Reconnect to the net.
- Update your AV.
- If AVG (I'm guessing that's the one you're going to install) refuses to update, go to the AVG forums, search for that problem (there will be literally thousands of search results) and apply one of the suggested fixes. The normal fix is to wait until the servers aren't overloaded.
I might be doing AVG a dis-service; up until recently, slow/ no updates was a common ssue, since the release of AVG 8. Maybe things have improved a bit, don't really know.
