Historically, there have been concerns about security vulnerabilities. Rootkits and malware could theoretically utilize hypervisor capabilities to hide themselves deep inside the system, making them nearly undetectable (a "Hyperjacking" attack). Within the isolated, virtualized sandbox of her CPU,

For a standard desktop user browsing the web? You might see a negligible impact (sometimes a theoretical 1-2% overhead due to slightly larger CPU page tables).
