We have a few customers running Vipre Anti-Virus, and we discovered this week a conflict between SiPass security system and Vipre. When we went to launch the security application the shortcut no longer pointed to the executable. The actual exe was missing.
It turned out that Vipre quarantined it. When the program got whitelisted the exe showed back up like nothing happened; however, we were now getting a an error saying there was potential virus.
Under the windows security settings everything was set for Vipre to be the Anti-virus and Windows defender was turned off. The issue was resolved after a reboot.
Let us know if this helped you…
