I don't remember who or where I got the idea to turn off the antivirus.
It is easy enough to do but I worry that if I should get a phone virus I may just allow it to propagate to the PC.
I do not recommend this. I know they say that "some" security software can interfere, but putting your machine and phone at risk seems to me worse. Therefore I would leave it on.
After you uninstall AVG with their uninstaller tool, remember to
reboot your machine.
Then do an uninstall and clean install of Avast:
1. Save a copy of newest version of Avast (5.0.677) for the version you need and save it to your HDD:
Free –

http://www.avast.com/pro-antivirus#tab4AIS –
http://files.avast.com/iavs5x/setup_ais.exe2. Download the Avast Uninstall Utility, aswClear5.exe
http://www.avast.com/uninstall-utility and save it to your HDD (it has uninstall tools for both 4.0 and 5.0).
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into
Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool.
6.
Reboot.
7. Install the newest version of Avast and
reboot.
8. Get Internet access and register your copy or add the license key for Free, Pro, or AIS.

If you still have problems, you may need to think about ZA FW. We have had users with conflicts with this and there are alternatives.
I would also suggest that you do not sync within the first 15 minutes of starting your machine since Avast may be pushing an update to your machine, and perhaps this may cause a conflict. But post back and let us know how things work and we'll take it one step at a time. Thank you.
