Hey guys, thanks for all of the good information. I will try your recommendations and report back.
A few other things......
First, why is AVG out of favor with people here? I have had decent luck with it over the years, especially for something free. Call me cheap, but I am VERY
partial to free stuff
Also, I do agree with the remarks that fresh installs are better. That is what I usually do myself with my own computers. However, in this case, this is my friend's computer, and he wants to keep his applications and settings. So if I can get his system disinfected then he will try that for a while. But it would not surprise me if we eventually do end up going with a new install at some point.
Regarding a possible reinstallation for him.......... I have gotten to the point where I usually buy dell systems for myself, in part, because the windows reinstallation disks are so easy to come by. However, this laptop is an MSI product. I do not have an MSI specific Windows installation disk.
I do have a Dell reinstallation disk. Can I use that to reinstall Windows on his laptop? He does
have an authentic Windows 7 license key. And thank the lord, it is still legible.
