Malil was charged late Monday with attempted murder with special circumstances of premeditation, causing great bodily injury and using a deadly weapon, said Deputy District Attorney Steven Carver.
Malil was scheduled to be arraigned Wednesday in Vista, north of San Diego, said Paul Levikow, a spokesman for the San Diego County District Attorney's office. He faces a maximum sentence of life in prison if convicted on all counts.
Authorities confirmed the victim's identity as Kendra Beebe. According to her Facebook page, she is a 35-year-old mother of two who works as an insurance broker in Carlsbad, a coastal suburb.
She was listed in critical condition Monday, according to the San Diego Sheriff's Department. Spokeswoman Jan Caldwell said Tuesday she had no update on Beebe's condition.
"Malil and the victim had apparently been in a dating relationship which recently ended," the Sheriff's Department said in a statement.
Malil's agent, Mark Measure of Abrams Artist Agency, declined to comment.
Malil, who lives in the Los Angeles suburb of Sherman Oaks, had taken the train to the San Diego area to meet his attorney, who had joined the actor's family and friends in persuading him to turn himself in, deputies said.
Deputies found the victim Sunday night while responding to reports of screams for help and breaking glass in San Marcos, about 15 miles east of Oceanside.
Malil appeared in the Budweiser "What are you doing?" commercial that aired during the 2001 Super Bowl, a spinoff of the "Whassup?" spots from the year before. He also played a co-worker, Haziz, to comedian Steve Carell's title character in "The 40-Year-Old Virgin," and has appeared in dozens of TV shows including "NYPD Blue" and "Scrubs."
