Sometimes an anti-virus program may block one of our applications, either during install, or after updates and one of the most common anti-virus apps that causes this issue is Avast.
However, in most cases unless the installer has been infected by a virus already on your computer, usually this is a false positive. According to our research, Avast has a long history of raising false positives
when scanning applications for viruses.
One reason for this is that their definition updates are completely automated, which means sometimes, they get it wrong. For instance one of these automated updates to Avast in 2013 false tagged hundreds of apps as infected, that were not actually infected with viruses.
Another possible cause is that Avast may simply detect the fact that the data mining type of program makes a lot of requests to scrape the data for you. Some malicious programs also make a lot of requests, but in our case, these are just the scraper functions searching and collecting information for you.
Resolving Avast's False Positives
To resolve this, you will need to change Avast's settings to tell it that the application you are installing is not malicious and should be allowed to run on your computer and access the internet.
We run Kaspersky Internet Security on all of our development workstations that touch our software release builds, including the one where the applications are built to protect you from viruses slipping into the release builds we send out.We also scan and install the release builds on Kaspersky protected computers before release to make sure they are clean.
