Since installing the new KAV 2010, version 188.8.131.523 my computers are running slower than with KAV 2009. One computer had Internet Explorer problems such as web sites freezing up if I could get them to load at all. Outlook Express is very slow. I went into the registry and found some KAV 2009 folders and deleted them. That seemed to stop the web site freezing up and made everything run faster. It also worked on my second computer. KAV does not do a very good uninstall when upgrading from the 2009 to the 2010. KAV 2009 must conflict with the newer 2010. I would still like to see better performance from the 2010 in the future. Anyone else with similar problems using KAV 2010?
