Hello bjovee,
Running Windows XP and upgraded from previous version when it expired. Followed tech support instructions (after a failed install following provided instructions with download) to remove all previous install with AVG remove tool. Then installed 2011. After install and while checking e-mail received "avgemc.exe malware" message - seems this is an AVG program being reported as malware. So I moved to vault.
Instructions/support notes are sparse and AVG support non-existent (email only and no response after 2 days). Would not recommend this company to anyone.
Really tired of companies with 'outsourced' (i.e,, minimal, non-helpful support with difficult accent to understand).
