Slow AV Scans – Why are my anti-virus scans so slow?
If you have noticed that your AV scans are running slower than normal, most likely,
the culprit is disk fragmentation (where files are broken up and scattered across
your hard drive). Disk fragmentation can have a severe impact on the speed and performance
of anti-virus and anti-spyware scan speeds.
The basic principle is that the greater the degree of fragmentation, the worse your computer will perform.
This holds true for anti-virus applications just as it would for any user interaction with a fragmented computer.
With virus attacks rippling through the Internet, the importance of fast virus scan
capabilities should go without saying.
Yet, if your PC is riddled with fragmentation, your AV scans will take significantly
longer to run, leaving you more susceptible to new virus attacks as they emerge.
If a defrag is not run regularly, your PC will build up a significant level of fragmentation.
This constant accumulation of fragmentation causes slow AV scans that get progressively slower over time.

What factors impact the speed of AV scans?
Many factors will have an impact on the speed of a complete anti-virus scan of your
hard drive. The way the scanner works, the total number of files that need to be
scanned, the size of the files, and the fragmentation level of the disk all have
a direct impact on the length of the AV scan process.

An anti-virus software will have to scan all the fragments of files which increases the time
required to do your AV scans.
The easiest way to increase the speed of your AV scans is to eliminate the fragmented
files on your PC. This can be accomplished through defrag (to handle existing fragmentation)
and prevention (to stop future fragmentation before it happens).
Diskeeper® performance software offers a simple solution that is designed
to do just this, automatically and seamlessly in the background.
Typical performance loss for AV scans without Diskeeper is about 28%.
"Diskeeper shaves off 10 minutes from a 40–minute
scan of about a TB."
As the capacity to quickly respond to new anti-virus attacks grows, so does the
importance of having a solution that allows for fast anti-virus scans. The overall
security of your PC data relies heavily on your anti-virus software’s ability to
quickly and efficiently do its job.
Diskeeper does more than just defrag (put your scattered files back together) your
PC. Diskeeper takes performance to the next level by preventing the majority of
the fragmentation that would otherwise cause increasingly slower AV scans, application
launch speeds, file access, boot-up, backup and more.
Try Diskeeper for yourself and see how much faster your AV scans and overall PC
speed and performance becomes.
