Anti-virus & Security software blocks ProSelect
UPDATED January 2017 - AVG2016 reported issue (see below)
Periodically we get reports of Anti-Virus/Security software causing issues by incorrectly thinking that ProSelect contains a virus. This can stop you from installing ProSelect, prevent ProSelect from running or, at worst, remove ProSelect from your computer! The first one is easy to spot because you usually get a message but often the latter ones just leave you wondering what's going on with no message unless you open the anti-virus software and look at its reports.
Since most Anti-Virus/Security software automatically updates itself, you can be happily using ProSelect one day, then the next day it just stops working because your anti-virus software now suddenly thinks ProSelect is a risk.
IMPORTANT: Provided you have downloaded and installed ProSelect from the TimeExposure website, the software is protected by a signed digital certificate and is not infected.
How can this happen?
One of the ways that Anti-virus/Security software looks for a virus is by searching for a particular "pattern" of data in a file that matches with that found in known virus software. There is always that possibility that other legitimate software (such as ProSelect) can contain the same pattern. Once notified, the anti-virus software developer will usually add an automatic exclusion for the legitimate software.
Checking if your Anti-Virus/Security Suite software is causing the problem
If ProSelect suddenly won't startup then try either
(a) Temporarily turning off or disabling your Anti-virus/Security software and see if ProSelect works again.
