Quickbooks Pro 2000 is acting funny after a "virus" attack. I use quotes because it wasn't a virus per se but one of those things that takes over your browsers. QBP2K is old but it does what I need.
Background:
XP Home w/o SP2. (IT pro friends advised against putting it on at this time.) I am on DSL, with a router/firewall and also use Tiny Personal Firewall to control connections in and out of the system.
I downloaded an mp3 via Kazaa Lite Revolution and played it while partly downloaded and my IE went nuts opening windows with ads etc. Firefox affected to a lesser extent. It was changing home pages and redirecting to ad pages.
I have run McAffee AntiVirus, Ad-Aware, installed and ran Microsoft AntiSpyware Beta, Stinger, Spybot Search & Destroy. All found various things which I deleted. I have run Hijack This and monitored Task Mgr and Software Uninstall, and studied those things that looked suspicious and deleted those that research said were malware. I have done what I can searching and removing registry keys.
The system seems normal now.
But not Quickbooks. It takes forever to open and when I click on certain functions like create or display an invoice there is a long pause and then I get an error dialog box titled "Server Busy" and says "This action cannot be completed because the other program is busy. Choose 'Switch To' to activate the busy program and correct the problem." There are then buttons for "Switch To" "Retry" and a grayed-out "Cancel" button. Hitting Retry simply brings the dialog box back. Clicking on Switch To is akin to hitting the Windows start button. Eventually I can get past this with enough tries and invoice subsystem seems normal. Closing Quickbooks also creates the same situation. I think most other functions are normal.
I was thinking maybe something simply got corrupted in the software but then again why would it even run at all? I started to reinstall it but stopped when it seemed that the installation process itself was having the same sluggishness even at the earliest stages which made me think it's more of a system problem.
But I can't find anything else wrong with the system. No mystery processes running soaking up machine time that I can see. I don't mind reinstalling QB but I hope I don't have to wipe the disk and reload Windows and everything else.
Any ideas?
