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,

Is there anyone that can tell me where I can purchase a really good,safe and reliable registry cleaner for windows XP? I’ve been searching all day and according to McAffee Site Advisor, most of them were bogus or either reviews on most of them were bad or not worth the money. I am looking in the range from .00 – .00. If anyone can help me I sure would appreciate it. Thanks so much!!

I just opened up windows XP after installing a clean copy and the key for my @ symbol and my " symbol are switched around. Is this the American layout? I live in the UK and I would like my " key to be on my ‘2’ button. Thanks!
