Final answer:
To prevent false positives for virus detections in a temporary folder, exclude the folder from antivirus scans. Other measures like renaming or moving the folder are less likely to address the issue of the antivirus software mistakenly identifying legitimate files as threats.
Step-by-step explanation:
If you have a temporary folder that periodically triggers false positives for virus detections when installing apps, the best course of action would be to exclude the folder from antivirus scans (Option A). This will prevent the antivirus software from scanning the folder and mistakenly flagging files as threats. Renaming the folder, deleting it, or moving it to a different drive (Options B, C, and D) may not necessarily solve the issue as the false positives are caused by the antivirus software mistakenly identifying legitimate files as malicious, and the same issue could recur even after taking those actions.
