This is not an ME problem. Your friend is crazy to have no Anti-virus software. Has he since added it? I just had my computer "cleaned" out. If he's on KaZaA, and even on the Internet, he may be getting swamped with AdWare and virus attacks. I had Spybot added, in addition to Hijackthis.zip, and on top of the Norton Anti-virus software. Best of luck to your friend's future computer health in the absense of anti-virus software. Getting Norton or something like it is the bare minimum advice I'd give.
I brought over my friends computer to remove is many viruses. After using AVG6,NAV,AD-Aware,Trojan Remover etc; I finally got a clean bill of health.It has remained clean since(He had no Antivirus protection on the system) I now hook up the computer to my network and i am able to get on line but cannot sustain connectivity once i exit the Internet. I cannot get back on without going through the long process of entering control panel,network,etc or sometimes i have to fool around with internet options, and even then i may sometimes get"server cannot be found" Most times a restart will help. Once i get on line i can surf freely, but should i close my IE Window, then the trouble begins. The system runs smoothly otherwise. I also got rid of the "Dust EXE" problem. Anyone care to give some help. System is 2.4GHZ, 128MB AMD DURON with WinME. Viruses and software that i removed are 19 Worm & Trojan, plus Kaaza & SBC-DSL.
