TOOL BARS!!!!
Get rid of TOOL BARS, most are just tracking machines that track everything you do on the internet, and some are very malicious, and do nothing but slow down your connection speed and take up CPU cycles, yes some can have nice little buttons that make it easier to find stuff, but for the most part just create these buttons yourself as a desk top icon, you will not believe how much better your computer will run.
I un-install every one that sneaks in.
Also I use Trend Micro Internet security pro, have never had a problem and I can password out all of my computers to stop Peer to peer network sharing, and other sites that are a good way to get malicious code from.
Also it doesn't download updates while your using the machine, and waits till a set time (you can set) after the last use before it will, and if it detects you using the machine again it halts the download until your done. it has a much more user friendly control settings, but the only thing I don't care for is the way the LOGS are, it doesn't really say what it found so you can look it up.
just remember even the best anti-virus/malware program cant do its job unless you exercise safe computing,
