Thank you for the response, and sorry for my late one.
Regarding your first suggestion, I'm not 100% sure what you mean by hiding far. I'm guessing you mean let it sit in toolbar and bring it back? The program lags from the first moment, and only unlags if I reinstall. I tried letting it sit in the background. It neither increases or decreases the lag.
The second option does not apply. I neither have network drives or a launch history as I deleted it all when I wiped the folder clean on the reinstall.
I'm testing another possible reason now. I managed to unlag FARR. I closed \online armor 4.5, which seemed to unlag it. Opening it again did not seem to lag FARR. Strangely enough, I run this set up on another laptop and have no problems. I'll report back after replicating the results a few times.
Edit: As it turns out, something was weird with Online Armor. I think the permissions were somehow screwed up despite my giving FARR trusted privileges. I'm guessing OA severely delayed FARR's response to my commands. In any case, I'm glad it's working fine again, and I hope if anyone ever has a problem this thread comes up, and they test their HIPS program. A complete removal and reinstall fixed the issue.
Thanks for your help Mouser, and anyone else that read the thread trying to find a solution.
