Vista Problem after Rootkit Virus kill

I was running Vista 32 with service pack 2 installed. After destroying a particularly vicious Rootkit Virus, I discovered I could not log onto the internet. Clearly the DNS and DHCP registries had been alterred. I did not have a restore point prior to virus install or removal. This rootkit lodged itself in lavasoft adaware, mozilla, explorer, and was redirecting all google enquiries and probably trying to export my private data. I had lost control of internet settings.

While hindsight is always perfect, I should not have asked advanced system care (which first discovered the virus) to remove it. I guess its like having an unqualified dentist remove a stubborn tooth. Only part of the virus was removed and it took essential parts of the OS with it.

I ended up using my Apple computer to try and research the question and download various virus removal programs...TDSS, Combofix, aswMBR, RKunhooker, av free, and several others.

A clean install of the OS was intimidating and very time consuming for reinstallation of programs.....an install that preserved user settings and programs would have been ideal, however:

1. Service Pack 1 did not include such a feature,

2. Service Pack 2 even if it did, was not on my disc and the creation of a slipstream version incorporating Service Pack 2 features was intimidating.

I acquired Windows 7 for an upgrade in the hope that I would have an OS that would allow an install preserving user settings and fix the registry entries that were not allowing me to access internet.

When I tried to install of course the partitions on hard drive were too small to allow the upgrade to occur. A lot of people have had this problem. I resorted to Partition Wizard Pro to merge my C partition with D to create enough space for the upgrade. Why couldn't Microsoft have included such a program with Windows 7 upgrade? Im sure it would have saved a lot of people a lot of time and money.

Why wouldn't Microsoft, with the release of Service Pack 2 for Vista not have facilitated the creation of a dvd to upgrade the capacity of legitimate users of Vista to boot using it?

Ah....Microsoft. I think all their engineers should spend some time learning the Mac OS.... it might encourage them to look at their system, customers and product development in a different way

Welcome
Although, I am not one of the malware experts, I have seen them say many times that with a rootkit the best remedy is to format and reinstall. There is no way to know if all the rootkit is gone.
You can buy an upgrade version of Seven for about $125.00
Or call the the supplier of your original Vista and for cost, about $25.00, you can get a replacement DVD, if you have the key number.
You can also try a factory reinstall, if your computer has a restoration partition.
If it were mine, I would not try to solve without a format and reinstall, regardless of what is written about the subject.
Many of our experts agree.
