Being relatively new to computers, my knowlege of them is rather limited, so hopefully someone can shed some light on my problem, recently my computer crashed, and Microsoft notified me immediately stating that the problem was a driver conflict with windows XP, the only things I have installed recently have been a new printer, a program called Kazaa, and the Avast4 antivirus program, I have unistalled Kazaa and the new printer, but the problem is still there although not as bad, after around 5 hours of running, my screensavers stop working, and all the icons on my desktop, together with any print disappear, has anybody else experienced this with Avast4? I am reluctant to delete it, as it has saved me from a virus already, and seems to be working fine, updating itself daily etc. I would appeciate any advice that may solve my dilema. Regards.
