hi, buddies, what about the threatfire, drivesentry, geswall (freeware), spyware terminator and ssm (system safety monitor) because I read good opinions abouth them? I meant in order to furnish extra protections to the avast av scanner due to lack of heuristics scan at the moment ( avast 5.0 will have proactive protection).they have stated they protect very well te pc against threats and malwares and they supply what a regular antivirus doesn't make. are they a good combination with avast and superantispyware? could you give to us your hints and experience about hardening it? I mean something with low resources not to get your pc a tortoise to harden it. best regards.
