First Profitable Quarter Following 13 Consecutive Quarters of Growth

MOUNTAIN VIEW, Calif. – November 1, 2006 – Commtouch® (NASDAQ: CTCH), the leading OEM provider of real time anti-spam, Zero-Hour™ virus protection and IP Reputation technology, today announced its third quarter results for the period ending September 30, 2006.

Highlights for the quarter ending September 30, 2006:

• Revenues: $1,866,000, an increase of 78% compared to revenues of $1,048,000 in the third quarter of 2005, and a 10% increase compared to revenues of $1,698,000 in the second quarter of 2006.

• GAAP Net Income: $149,000, achieved after 13 consecutive quarters of double-digit growth. This is compared to net loss of $855,000 in the same quarter in 2005, and compared to net loss of $114,000 in the second quarter of 2006.

• Non-GAAP Net Income: $315,000, compared to a Non–GAAP loss of $412,000 in the same quarter in 2005, and an increase of 518% compared to a Non-GAAP net income of $51,000 in the second quarter of 2006 (Refer to the “Use of Non-GAAP Measures” section and accompanying financial table for reconciliation of GAAP financial information to Non-GAAP).

• Deferred Revenues (long term and short term): $2,588,000, an increase of approximately 4% compared to deferred revenues of $2,483,000 as of June 30, 2006.

• Cash and marketable securities: an increase of approximately $862,000, to approximately $9,059,000, due to the company being cash positive for the fourth consecutive quarter and receipt of proceeds from warrant and option exercises (approximately $639,000).

• The company signed nine OEM licensing agreements during the third quarter, bringing the company’s global OEM partner count to fifty at the close of the quarter.

Commtouch CEO Gideon Mantel said: “The problem of SPAM and email-borne viruses has significantly increased over the last six months, causing increasing damage to the entire Internet community. Since traditional solutions have lacked the capability to compete against the new threats, the demand for our solution has increased over time, demonstrated in the record number of new OEM deals signed this past quarter. I am very proud that we have reached a major milestone in attaining profitability in the third quarter of 2006. We are confident in our ability to continue to grow the company while keeping high profit margins.”

Use of Non-GAAP Measures

This press release includes financial measures for net income (loss), basic and diluted earnings per share that exclude stock-based compensation expense and are therefore not calculated in accordance with generally accepted accounting principles (GAAP). Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance that enhances management's and investors' ability to evaluate the company's net income or net loss and earnings or loss per share and to compare it with historical net income or net loss and earnings or loss per share, including for the period prior to the adoption of FAS 123R by the company effective January 1, 2006.

The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. Management uses both GAAP and non-GAAP measures when evaluating the business internally and therefore felt it important to make these non-GAAP adjustments available to investors.
