I run Norton 360 and Ad-Aware paid version plus free version MalwareBytes, Spybot and Microsoft Security Essential. Microsoft Essentials takes quite a bit of time to do a complete full scan on your computer along with MalwareBytes and Ad-Adware. To my surprise, Microsoft Security Essential was the only one that caught the W32/Alureon.A Trojan virus and quarantined it. For a free download to remove this Trojan, go to "Just download.com" and type in "W32/Alureion Trojan Removal Tool.1.0" in the search box and scroll down to this tool. Down load it and let it scan you computer. It will find it and remove it. Hope this might be of some help.

Were your freeware programs updated to the up to the minute releases prior to scanning?

We have a removal guide for this infection: How to remove Google Redirects or the TDSS, TDL3, Alureon rootkit using TDSSKiller

BTW, the speed and ability to complete an anti-virus or anti-malware scan depends on a variety of factors.
  • The program itself and how its scanning engine is designed to scan: using a signature database vs heuristic scanning or a combination of both.
  • Options to scan for spyware, adware, riskware and potentially unwanted programs (PUPS).
  • Options to scan memory, boot sectors, registry and alternate data streams (ADS).
  • Type of scan performed: Deep, Quick or Custom scanning.
  • What action has to be performed when malware is detected.
  • A computer's hard drive size.
  • Disk used capacity (number of files to include temporary files) that have to be scanned.
  • Types of files (.exe, .dll, .sys, .cab, archived, compressed, packed, email, etc) that are scanned.
  • Whether external drives are included in the scan.
  • Competition for and utilization of system resources by the scanner.
  • Other running processes and programs in the background.
  • Interference from malware.
  • Interference from the user.
-- Note: Using two security scanning engines at the same time can cause each to interfere with the other, cause systems hangs, false detections, unreliable results and other unpredictable behavior.

To speed up your scans, uninstall unnecessary programs, clean out the temporary files or use ATF Cleaner first, temporarily disable any other real-time protection tools, close all open programs and do not use the computer during the scan. If the scan still seems slow or hangs, then try performing the scan in "safe mode".

Note: It is not unusual for an anti-virus or anti-malware scanner to be suspicious of some compressed, archived, .cab and packed files because they have difficulty reading what is inside them. These kind of files often trigger alerts by security software using heuristic detection because they are resistant to scanning (difficult to read). This resistance may also result in some scanners to stall (hang) on these particular types of files or just ignore (skip) them. Certain files in the System Volume Information Folder like the Tracking.log (created by the Distributed Link Tracking Service to store maintenance information) have also been reported as a source causing some scanners to hang.

Yes, I ran each product by itself. I wonder if this might be a false virus. It appears that this virus was in a hard drive that crashed and lost its sector. I was able to hook it up to another hard drive and down load all the information to the newer drive. I also bought a new hard drive and installed that also. I have two. I also bought a WD external backup hard drive and download the information from the newer drive and installed it into my latest hard drive. After I found the virus with Microsoft's anti-virus and scanned my new drive and also found it there. I must have just passed this virus from one drive to another without scanning first. Stupid me. I'm not sure where to start here since I've been told that one software program cannot protect from all threats. Norton 360 is my primary anti-virus protector. Am I messing up here? That's for the replies.

Running TDSSKiller should confirm whether or not your machine is still infected.
