when i load explorer i get windows installer trying to install HPIZplus450?

I had this same problem; all of a sudden, one day every time I brought up an IE browser window, this pesky HPIZplus450 would try and install itself, and if I didn't cancel it right away, I had to sit there and click off box after box of errors before I finally could cancel it. This would usually happen 2 or 3 times before I could turn it off.

I went to www.Dogpile.com and tried to research it, and found somewhere that said it had something to do with the Hewlett-Packard Image Zone software, and since my equipment is all made by HP, I decided to contact them.

I went to www.hp.com and chose 'Contact HP', wrote them a letter to which they responded 'go to Start-Run' and type 'msconfig' and on the 'Startup' tab go and un-choose the box next to HP Image Zone. When I did this, the Windows XP operating system gave me an error each time I rebooted the machine, and it didn't quit trying to install HPIZplus450. HP wrote me a follow-up letter asking if their suggestion had fixed the problem and when I explained what had happened, they said to choose to restore the original configuration, an option given each time the machine re-boots, and then go to the Control Panel and choose Add/Remove programs. I 'Removed' the HP Image Zone program, and that finally took care of it.

I apologize for the lengthy explanation, but I wanted you to understand the entire process, so that it might better assist you in correcting your problem. Best of luck to you.

Might be a virus?

Try running Anti Virus, Spyware removal, and adware remover. May help your problem.

Programs to use: AVG Anti Virus, Spyboy Search and Destroy, Ad Aware, and Ewido.

Also try going to a webpage, clicking tools, delete files, delete cookies and delete history.

Make sure your Homepage under the general tab is the same as it was before. If it isnt set it to www.yahoo.com.
