Helkerm attack???? 2 questions.?

i went online and this window from my virus protection just popped up, out of the blue. I expected something like "scan completed" but it said my computer has had a helkerm attack!! Are those viruses bad?! Or are they like mid range or low in category?

2. I tried to exit the window, first I tried just exing out, but it didnt work, then I tried task messenger, it didnt work then I x'ed out of that and it said window is locked by computer and/or OWNER. windows has had a problem and needs to close. Then it said when it started back up,2354676343424678899563456345 ERROR%26gt;355

Was it the attack or a virus?!
