Windows Installer Corruption after Trojan Resolution

Hello,

I recently went through a successful remediation of an internet virus/trojan that infected our computer. See here: http://forums.whatthetech.com/w32_agent_pz…496#entry482496

Since the remediation, I am now unable to remove some programs via Add/Remove Programs; specifically Microsoft Live (terrible software).

I am also unable to launch an existing Excel file directly but instead have to open New Office Document, chose Blank Workbook, allow Excel to load and then open a document through the file - open menus.

I also noticed that it failed to upgrade Office 2003 to SP3.

This all started after I contracted the virus which was days after XP upgraded to SP3.

Here are some screenshots of the errors I receive.

I also can't load Microsoft Outlook in my wife's profile, it gives an Avast plug in error and Outlook goes Not Responding every time.

Please help, I really don't want to reload the entire computer from scratch.

See here for uninstalling One care. It has instructions for manual uninstall if needed: http://forums.microsoft.com/WindowsOneCare…06&SiteID=2

For Excel, what is the deault action shown (hilighted) when you right click on a xls file? On mine it's Open. Also, if you look at the Filetypes tab in Folder Options, what program is associated with it? Should be Microsoft Excel.

For Windows Installer, try installing the Windows Installer 3.1 Redistributable (v2)

For the Avast problem, uninstall and reinstall it.

Hey, Thanks for the response. This thread can be closed, I decided to invest the day reloading my machine. It's all good now.

Probably the fastest and surest way to get it all working again for sure. Thanks for letting us know.
