You prolly have this problem unless youve already had an encounter with this crap. Anyway its like many lil viruses all taking their turn on your comp. it can really bog you down and in prolonged exposure take out your whole system. to solve this search for either Spybot search and destroy on google or Adaware6. I used to have adaware 5 but it went obsolete and it took several months for 6 to come out. Spybot works great JUST KEEP IT UPDATED!!!! and a word of caution if you have 500+ errors when you run it expect having to format your computer. or you can leave it on your system and let any schmoe look at what your doing.
