I have this problem that i would of post it as a reply to another post here, but it was too old, and i was told to do a new topic. This first occurred today, when i was checking bios, if there´s something wrong in the adjustments. I found that there was new drive, "WAMSUNG", in the bootdisk priority list. I was checking BIOS cause my computer has turned amazingly slow on games, even though i have just bought a new motherboard (AsRock K7vt4A+), more memory (2x512 ddr400MHz), new cpu, (AMD SEMPRON 2600+) and new graphics card (GeForce 6600GT. They all worked just fine for some time, specially after i installed a new driver for graphics card (forceware 81.85). But now, for few days, theres been a serious problem with ability to run games etc... So I have started to suspect that there´s a virus or somekind other malicious program doing this. That WAMSUNG (as it first appeared in BIOS) sounds like a human created "evil joke" you know. Especially just a moment ago, when I rebooted my machine, there came a announcement that a new device is found: "SEMWUNG$ CD-VOM WC 148F". Really, it sounds like a bad joke or something. That CD-VOM (!?) can be found in my device management too. Maybe it´s time to install Norton Antivirus 2005 back, and see if it can do something.. Seen That, Been There, Wrecked That..
