Final answer:
Using spyware-detection applications may not always catch all spyware due to constantly evolving spyware methods. They can generate false positives, incorrectly flagging benign software as harmful, and they might slow down your computer during scans.
Step-by-step explanation:
Disadvantage of Using Spyware-Detection Applications
One disadvantage of using a spyware-detection application to remove spyware from your computer is that it may not be able to detect all forms of spyware. This is because spyware creators constantly evolve their methods to avoid detection. Another potential disadvantage is that spyware-detection programs can sometimes generate false positives, mistakenly identifying legitimate software as malicious. This can lead to the unintentional removal of important programs or files. Additionally, some spyware-detection tools may have a significant impact on system resources, causing the computer to run slower when these tools are scanning for or removing spyware.
