I am running Windows Vista on my laptop and when performing a full scan using a fully updated Malwarebytes, the scan consistently hangs after about an hour while scanning the same file each time (D:\SwSetup\Audio\V32\WaveRTv.ini). I can complete a quick scan, but the full scan will not complete.

WaveRTv.ini is part of Hewlett-Packard's Conexant High Definition Audio Driver package.

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 for suspicious behavior or a combination of both.
  • Options to scan for spyware, adware, riskware and potentially unwanted or unsafe 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.
  • Type of operating system installed on the computer.
  • 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, .tmp, .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.
To speed up your scans, clean out the temporary files or use ATF Cleaner first, temporarily disable any other real-time protection tools, close all open programs, do not use the computer during the scan and then make sure you only do a Quick Scan. Malwarebytes Anti-Malware is designed to remove malware as effectively with a Quick Scan as it will with a Full Scan which takes much longer to complete. Both do full heuristics, memory, load points and multiple other malware checks. The Quick Scan looks at the most prevalent places for active malware so scanning every single file on the drive isn't always necessary. The Full Scan only has the ability to catch more traces in rare circumstances.

Note: When doing a Full scan, 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 scanning (difficult to read) or they may even be ignored (not scanned). This resistance may also result in some scanners to stall (hang) on these particular types of files. Certain files in the System Volume Information Folder like the Tracking.log which is created by the Distributed Link Tracking Service to store maintenance information have also been reported as a source causing some scanners to hang.

Thanks.

My AVG also hangs on the D:\SwSetup\Audio\V32\ folder, however. Is there any way to remedy this in order to allow any of my anti-virus programs to complete their scans?

If the scan still seems slow or hangs, then try performing the scan in "safe mode".
