Hi Bill,
An upgrade won't increase removal capability on an already infected computer. The free and paid versions of Ad-Aware have the same removal ability.
The Ad-Aware Plus and Pro versions advantage is the realtime protection feature to avoid infections in the first place.
It sounds like you have encountered a virus or trojan that has downloaded some assorted malware to your computer which may take a combined effort of Antivirus tools and other specialized removal steps in addition to the Ad-Aware program you have been using.
Let's get your computer cleaned up first and then you can decide if you want to upgrade to Ad-Aware Plus or Pro because it might not even download or install right on an infected PC
I like to start with a look at these logs please:
1. Your Adaware Scan log
As Logs are stored in :
C:\Documents and Settings\USERNAME\Application Data\Lavasoft\Ad-aware\Logs\.
An easy way to get there is to
click Start,
click Run
And type in and press ENTER:
%appdata% then click Lavasoft
then Ad-Aware
and then Logs.
scroll down to find the latest one that you have
(by date & time)and open it right Click select all
copy and then paste the contents of it here.
