I was online the other day and my antivirus and firewall came up like 100x rapid fire with a bunch of stuff, I tried blocking and deleting them all and it still comes up every now and then.. and in my processes when I hit ctrl alt del, theres something called "mssearchnet.exe" and if I hit end process it comes back, and whatever kavsvc.exe is it's running at like 70-99 on the CPU part where the double digit # is. I have windows XP, it's making my computer sluggish, and also my internet. What can I do? I've used a scan and it can't delete them.
