As i have many just now repurchased Trend Micro Pro and at the same time bought a computer from a local computer repair shop becuase it had windows xp x64 on it i thought it was well worth it since so many problems vista has, but any one have any idea what antivirus software will work, everytime i try to install my software or different versions of it to see wich work i keep on getting a message to read my installation documentation and what i am installing is a 64bit installer file
anything else that might work,

im just looking for cleaners to protect me from all sorts of stuff i would rather free stuff but if its heaps good i would like to know
i have trend micro and avast and cccleaner i did have AVG but i think thats is a waste all it does is just donwload updates and never finds stuff best free virus cleaner is avast trend micro is ok but it hasent piked up any viruses yet which is a bit sus ??? and i heard norton when it runs out puts viruses on your computer ???
