I would like to ask two quesitons: I have eset nod32 antivirus version 3 since two years on my PC. 1) Does nod32 antivirus protect my PC for antispyware or do I have to buy a special software for it (p.e. superantispyware)? 2) Since a few months I noted a high cpu usage when system is idle. Can it be eset nod32? Does nod32 system operations when my system is idle?
