[Arquivado] PC reiniciando sozinho e possível infecção

Olá. Recentemente estou com um problema no PC que ele anda reiniciando sozinho e, hoje, o google chrome parou de funcionar e o antivirus Microsoft Security Essentials sumiu. Então instalei um Avira que tinha há algum tempo no PC. O estranho foi quando estava instalado, apareceu uma tela pequena, como se tivesse algo sido movido. Fui no executar > msconfig e, estava escrito lá Internet Explorer e o local Startup (como mostrado na imagem). Desde então, quando o pC reinicia, o Chrome para de funcionar, como se tivesse sido desinstalado. As vezes o explorer.exe some também.

Quando o PC liga, o Internet Explorer inicia sozinho. Tentei desativar essa entrada do Internet Explorer e, aparece uma mensagem dizendo que não pode ser alterada, falando algo relacionado a administrador, mas eu uso Windows XP e está normal.
