Just wanted to say what a great piece of software Prevx is . My friend somehow (im guessing something XXX rated ) was infected with a rootkit. The PC would not boot into normal mode, so I went into safe mode and downloaded prevx 3.0 Free version. Went in manually and deleted everything that it found. Worked like a charm . All other apps I tried would delete certain files, but they would always come back. Prevx found the main culprit and got me back into normal mode. KEEP UP THE GOOD WORK!!!
