My internet connection has gotten much slower over the past few months. I have deleted all the temporary internet files, but that didn't help much. I've heard that programs end up on your computer after a while and you're not aware of them. I'd like to scan for any spyware programs, but don't have a program to do so. There are a bunch of them out there, but I don't know which ones are good. I'd like to get one that's either cheap or free, but does a good job. Any suggestions on programs or procedures that will restore the speed?
