Deleted files I shouldn't have...help please

My wifes computer was having problems and a virus. I ran spybot search and destroy, and deleted some files I guess I shoudn't have.

I started trying to install AVG and it wouldn't let me.

I downloaded all the tools in the read me here on the forum and saved to a cd to place on her computer (which I did save them on her computer)

It won't let me install with the error that keeps coming up saying:"The windows installer service could not be accessed. This can occur if the windows Installer is not correctly installed. Contact your support personnel for assistance".

I have tried to go in and set it to manual, automatic with no success. I tried to download from the microsoft site with no success.

When I had tried to install the AVG the other night it kept telling me This couldnt be done in Safe Mode, and I wasn't in safe mode.

I know I have screwed up, any help is greatly appreciated

I started a post under malware and Tim tried to help me, and said maybe I can get some OS help so that I may continue with the cleanup tools.

Thank you,
Brent

 

what brand computer is this? what os? do have an instillation disc? you prob need to reinstall the os, easier than trying to fix it perhaps.

 

sorry, I forgot to add that.

It's an HP
Running Vista Home Basic - 6.0.6002 srvc pack 2 build 6002

No We dont have OS disc. It didnt come with one, and I didnt buy one.
I have tried system restore and everything to no avail

There is a partition with a recovery on it, but can't figure out how to get it to run, since system restore or anything will work.

i have an hp with w7 & if you click start all programs then recovery manager & follow the options to restore your hp back to factory settings.

 

It says this program will NOT reinstall drivers or the windows Vista OS.....:confused

 

wow. either the virus really has you by the b*lls or you really deleted some files lol. since you don't have a os disc can't access the D partition, call HP <YIKES!!>

 

all it says thats on there are programs that came on computer when new......It doesnt reinstall OS or drivers.....

I think I deleted some kinda reg files when I ran the spybot search and destroy...I dunno

 

i think when you first turn the pc on & the blue hp screen appears you have to tap F11 and boot from recovery console. i don't really know. call HP tech support!

 

oops.. try this one :-D
