I recently have started having a problem with Avira free anti virus. I have had it on my pc for many months with no problems, then all of a sudden it has started to freeze up during scans. I tried uninstalling and reinstalling it with the same results. I ran Malewarebytes and it finds no problems, I even installed a fresh copy and did not update it , thinking that maybe it was an update problem since it worked for months just fine, but still the same results..it hangs up. It may even be a a certain file. Anyway was just wondering if this was a common problem of if someone else has had this problem.

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.
  • 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.
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. 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.
