Caller didn't leave message. Other web sites with complaints on caller, state caller pretends your computer has something wrong with it. Others get a call from this number stating they're the IRS & they're going to sue them.

How lame.

1. A computer company does not call you up.
2. IRS would not only call, but they would send you a certified letter of the problem so they actually have confirmation you received the info they're trying to tell you.
