How do you find all the nice virus place's?

Mettaur - First, you need to obtain the WWW-ID by completing the "Help with Rehab" job.

Then go to ACDC 1 and open the locked door(it's purple and marked with a skull). Check one of the corners, and you will encounter Mettaur, Mettaur2, and Mettaur3. If you win, there will be a cutscene where Megaman catches them.

Bunny - Make sure you have 50 BugFrags. There should be a job marked, "Please Adopt a Virus". The navi will ask you for the BugFrags and she will give you the Bunny Virus.

Spikey - Go to Hades Isle and jack into one of the gargoyle statues. It is in that area. You will be faced with Spikey, Spikey2, and Spikey3. If you win, there will be another cutscene.

Swordy - Go to Undernet 1. When you enter go forward and turn left at the second left turn. They are located in the corner. You will be faced with Swordy, Swordy2, and Swordy3. If you win, you know what will happen.

Jelly - Go to Beach 2. Travel down the path, and take a left at the first intersection. Follow the path to the end and face the Jelly viruses.

Mushy - Take the CyberMetro to SciLab. Navigate that area until you see a little stand with nobody behind it. Go behind that stand and look in the right corner to encounter the virus.

Momogra - Go to ZooComp4. Look at the end of the main path where you fought BeastMan.

KillrEye - Go to ACDC school and jack into the principal's computer. Go to the first row of desks and move all the way up and to the right. You should see some sort of cyber chalkboard. The virus is in this area.

Scuttlst & Scuttlst 2 - These are more complicated. Scuttlst is located in Secret 1 in the left corner. Scuttlst 2 is located in Secret 3. Travel on the compressed path, and follow the main path(Do not turn unless you have no other way to go). Keep going until you uncompress. You should encounter the viruses.

After you capture the viruses, go to the Virus Lab in SciLab to retrieve your viruschips. They also count as standard battle chips.
