5. A Sudden Lack of Storage Space

While not all computer viruses exhibit this behavior, the ones that due tend to multiply rapidly. This directly leads to a decrease in storage space as the malicious files take up more and more room on your machine.

Occasionally, a virus infection will have the secondary effect of deleting or moving your files in a seemingly random manner. Other types of infections (such as ransomware) are far more organized in their efforts.
