Recentley I had problems with enabling SPYWAREBLASTER . I had a tricky Trojan horse also, which may have influenced this. All I want is that SPYWAREBLASTER works. It says whatever , but the thing is I actually got it up and running, untill I rebooted my computer. then it all went to hell. I have been working on getting rid of a TROJAN HORSE which is creating havoc on my computer. It is a sneaky horse and possibly renames itself. I am using AVG free edition, plus SPYBOT S@D, plus FREE INTERNET ERASOR .I have requested advice from JAVACOOL and got nothing. ZILTCH. I cannot be the only one that has this problem. "error code 4 please consult author." I don't think getting drunk will solve the problem, but ......what can I do?
