I've tried using Sysclean but there wasn't any virus found. is it normal for the sysclean log to show that ... e.g., Could not set file for reading on "C:\Windows\Prefetch\....." access is denied.
or "an error occured while scanning file... access is denied."?

and also, i'd like to further add on that on May 22nd [i know the date 'cause avg test result logs it], when I brought up task manager, I saw a.exe running. I checked my firewall log, it was trying to connect to an irc server. the traffic was blocked by my fw. suspicious about that, I went to download avg to scan my comp. sure enough, avg found a "trojan horse IRC/backdoor.sdbot.rox". & avg deleted that sdbot.
just thought i should mention that.



& I clicked on "fix" for hijackthis[referring to previous posts].
even though I've "fixed" those entries, explorer.exe is still trying to connect to antrexhost.


& meh, now my fw has an error... whenever i start up my comp, it says

Sygate Agent Firewall has encountered a problem and needs to close. We are sorry for the inconvenience
szAppName : Smc.exe szAppVer : 5.6.0.2808 szModName : trident.dll
szModVer : 5.5.0.0 offset : 0007394a

I havent tried logging to the net with my desktop since then.

looks like I need to get a new freeware fw now....
