After running the Ad-Aware SE Personal Scan, All Modes, with the Definitions Up-To Date, the Results indicated that there were NO Critical Objects! BUT when I ran the Computer Associates Web-Site Pest Patrol Scanner it Indicated that my Computer is Infected with the EstAlive PEST- Alias- AdWare.Win32.IEHlpr.e [Kasperksy], Trojan.SmartAllYes [Symantec]! Why did this happen & what should I do?
