Sneiderman was accused of hindering the apprehension of a criminal, concealment of material facts, four counts of making false statements, and seven counts of perjury, totaling 13 charges.
She was found not guilty on three counts of perjury and one charge of making a false statement.
A DeKalb County, Ga., jury returned the verdict Monday afternoon after nearly 11 hours of deliberation.
The 37-year-old widow and mother of two denied any attempt to cover up her alleged affair with her former boss, Hemy Neuman.
Neuman is serving a life sentence for the November 2010 murder of Sneiderman's husband, Rusty Sneiderman, who was shot outside a daycare center.
Each charge carries a maximum sentence of five to 10 years in prison, and sentencing is scheduled for 9 a.m. Tuesday.
