infection aux trojans

[b]bonsoir,

j'ai des ralentissements graves de mon pc.

mon anti virus a détecté deux trojans :
- trojan.win32.dialer.eg
- win32 trojandownloader.zlob

je n'ai pas beaucoup de connaissances en informatique et je ne sais pas comment m'en débarrasser.

je vous remercie de bien vouloir m'aider.
