I had AdAware SE, HiJackThis, Spybot S&D, CW Shredder, AboutBuster, and the free AVG virus software, and I thought I was 'clean', but I tried running a trial version of Spyware Doctor and it found 499 infections!! Is that for real? The trial version killed 400+ but said I had to buy the software to kill the remaining 70+ infections. What gives, and should I buy it? Attached is the log file it spit out.
