I have a valid Windows XP software with key. I have HP Scanjet4070 photosmart scanner and HP Photosmart 8158 printer. I also a valid antivirus and internet securty suit (Cyberdefender) with activation code. I regularly use broadband internet connection through DSL I regularly, almost daily update my antivirus and internet security suit. I do not turn on Windows updates nor do I download windows security updates. The system functions without any hitch for a few weeks, say 6 or 8 weeks. All the spywares and virus are regularly detected and removed. In spite of doing so some of the windows exe files gets corrupted. This has happened 5-8 times during the last 18 months. Everytime I have to call the engineer to format the HDD and reload all the programmes. I have 512 MB RAM and 60 GB HDD and have HP Vectra model that was purchased in Jan 2001. If, after loading fresh/new Windows XP should I go for Windows updates and also install updates for my printer as well as scanner drivers? What should be done to overcome this regular problem? Kindly give suitable advice.
