I'm losing the battle my brothers and sisters. It seems like something new breaks down on KL each and every day.

two more Trojans popped up on my machine. It is becoming aware and spreading fast. Smart buggers out smarted me but the battle wages on...

I'm exhausted and tired and sick of the 21st century.

    Simple scan might not get rid of trojans. It has already infected ur system folder so ull need to either do a thorough scan or manually rid of the infection. If all else fails, reformat.

    Some trojans and viruses are really tricky to get rid of. You have to attack them differently, depending on how they are attacking your system. Some will stay resident in memory upon bootup and "phone home" once a network connection is detected to re-enable whatever was disabled via the antivirus program. Some will mutate in resident memory and trick the antivirus program without heuristics capability to detect them.

    I had to fix a friend's computer that prevented bootup completely. She paid an arm and a leg for people to come to fix it but they couldn't because the message on bootup would lead you to believe it was a hardware issue, when in reality, after some investigative work, it was a software issue, mainly a trojan. It resided in the browser cache location and piggybacked on the browser upon network connection to open up any urls and execute any code it deemed necessary for its survival, including preventing a complete bootup.

    So I took out the hard drive and brought it to another computer and made sure not to execute anything on the infected drive. I ran a deep scan and the virus scanner was able to pinpoint the location. The advantage of "sandboxing" the infected drive is that you don't have it running in memory and compromising your scans. Once I pinpointed the location, I proceeded to delete all the junk. Once I replaced the infected computer with a cleaned up drive, it booted perfectly.

    It's a tricky business getting rid of viruses and trojans. And if all else fails, Tidus is right, just reformat the hard drive. Unless it is a bios virus or a virus that attacks the MBR of the hard drives, then a reformat will work.

    One of the Trojan came from Ages of Empire 3 and the other one piggy backed off a N64 emulator. I was in some mood for Ocarina of Time and paid the price for it. The system is clean for now. I went deep into the root directory and manually cleared it out.

    No need for any of that now since I've just spent a good part of the afternoon/evening cleaning up my computer. I am good for now.

    Tomorrow, I will buy myself a six pack and I'm going to ice that in the freezer like a freshly caught Salmon. A non-bombastic celebration for my small victory.
