hi, My windows firewall turned off by itself last night, so I switched it back on again and ran my AVG. I found 110 win 32/crypor virus's and removed 106. This left 4 on the processor that it could not remove. I have now installed Avast and it is scanning at this moment. How do I switch off AVG, as I understand that only one antivirus is recommended. Or must I unistall AVG completely?
