I got a new client with 1 server 2003 and 6 workstations. I went to evaluate the systems and the workstations had an antispyware called: SuperAntispyware install on each one, I updated the Antispyware and start scanning the systems and to my surprise the program detected on each computer close to 1,000(Adware, spyware and several Trojans), needed a lot of the Microsoft updates, in 2 computers could not even update the Antivirus. I try to clean one of the computers and after cleaning it would not take me to the LOG ON SCREEN(was just looping for 15 minutes) so what I did was to go to the Last known good configuration and I was able to log on again.
Question: What would be your approach to this situation as I was thinking cleaning and removing the virus and spyware but on doing this I know that some programs will not work properly and some infected files will disappear. I need to have an idea to what is best for my client and show him the different options.
Please advise me guys.
