Read time 6 minutes

Deploying legitimate antivirus programs enhances the performance of your machine, protects your system from external threats and allows you to take actions such as delete/quarantine viruses. Every antivirus program has its set of algorithms to work; some allow specific programs to make changes to your system while others treat the same as potential threats.

Antivirus programs also have a certain impact on desktop-based applications like MS Outlook. It has been reported by most of Outlook users that they face issues while operating Outlook on an antivirus protected machine. As we know, a PST file is loaded each time you launch Outlook and it’s quite possible that the antivirus software that is currently running on your machine restricts Outlook from loading the PST file. Moreover, if your PST file is virus infected and the antivirus installed is not powerful enough to remove viruses from the file, then your PST becomes inaccessible.

A user may encounter one of the following error messages if their antivirus blocks Outlook.

“Your Anti-Virus software has blocked the file you were trying to open”

“Outlook PST is in use and cannot be accessed”

Apart from these, there are several other issues that antivirus programs create.
