Just want to check if anyone else experienced something similar. Early this morning I updated the avast software and after that my computer was more or less unusable. It made my network connection go down, it slowed everything down so it took ages to start programs up and some would just sit there and do nothing after I got them running. Had to do a system restore to get everything working again which also took ages to do. Uninstalled avast and installed it again with the latest installation file and now things seem to work just fine.
