FAQ: Why does my anti virus software detect that the Viewer is malicious and a security risk?

The virus alert is a false positive.

Safeguard Viewer deploys system hooks during installation so that it can monitor use of the print screen key and processes running (to prevent third party screen grabbers and printing to certain print drivers) and the anti-virus application takes this to be suspicious behavior.  In addition, we use various methods to protect the SafeguardViewer.exe file from being hacked and these measures can also trigger false positives.

Users may have to disable their anti-virus software before installing the Viewer software.


Make sure that you always download the Viewer from the LockLizard web site and not a third party site because some sites offer a supposedly cracked viewer that does actually contain a virus.
