BleepingComputer.com: Replacing certificates and removing any that may be harmful

I posted a few days ago about some problems. My post was move to the malware section. That issue has been resolved, but they asked me to re-post the certificate question here.

I deleted all of my certificates, thinking that one was corrupted somehow. I now do not think this is the case. My previous company used Fortinet and just merged with another company. I believe many of the strange occurrences were due to their new and different Fortinet settings. But now i need to replace my certificates.

Thanks

From what I see...each certificate will have to be "replaced" individually, by whatever process led to it being issued in the first place.
