Thread: Downgrading to xp

My Lenovo 3000H Series PC configuration is an Intel Pentium Dual Core (1.86GHz), 160 GB HDD and 1 GB RAM. I use Vista Home Basic. Even though I have Quick Heal Anti virus Plus 2009 (SP1) installed with latest updates, Windows Security Centre shows me a message saying "Windows did not find an anti-virus software on this computer". How do I correct this?
I also wanted to ask you if I can install Windows XP (Professional or Home Edition) on this computer since it came pre-installed with Windows Vista Home Basic.

There might be some kind of interfacing glitch between the anti-virus and Windows. One way to get rid of the error is to manually set, Windows to ignore the antivirus alert. Go to the Security . Center from the Windows Control Panel. Click on Check Settings for the anti-virus component and click on I have no anti virus that I'll monitor myself. Yes you can install Windows XP in a dualboot configuration on top of your existing Vista Home Basic installation. You might need to prepare a partition for the installation though.
