Granted, my computer's getting old, but it's not that old (about four to five years now--should be switching to a Mac after this semester).
I am using Malware Bytes Anti-Malware, avast!, Spyware Guard, and Spyware Blaster (I stopped using Ad-Adware because it was really bloaty and made my computer run super slow, especially with this new anniversary edition they came out with). If it means anything, the school has a firewall (though I am not sure what kind) and uses Cisco Clean Access Agent. I use no other anti-virus programs.
Start up and shut down times is what is being affected, for the most part. It's not super slow, but it's not as fast as I've seen it go either.
P.S. Sorry for the late reply. Haven't checked on this forum recently. Apparently, I can't subscribe to topics and get them through e-mail. =/
