TORONTO, November 18, 1998 -- Seventy per cent of all antivirus software sold by resellers in Canada during September 1998 was Symantec Corporation’s (Nasdaq: SMYC) Norton Antivirus, according to just released marketshare data from AC Nielsen Company of Canada Limited.

"This demonstrates that Canadians prefer Symantec’s new Norton Antivirus 5.0 for Windows far more than any competitive product," says Symantec Corporation’s Canadian general manager Chris Monnette. "This is a strong indication of our customers' belief in our previously-announced antivirus partnerships with IBM and Intel," he adds.

The same data also shows that for the first nine months of 1998, Symantec represented 46 per cent of all antivirus units sold through resellers. This is up from 41 per cent compared with the same period in 1997. Symantec’s nearest competitor has only 38 per cent of the same market in Canada.

In the Windows-based fax software category, Symantec’s WinFax Pro 9.0 scored virtually 100 per cent of the market for the first nine months of 1998; in the Windows remote control category, Symantec had 90 per cent marketshare according to AC Nielsen’s data.

"The marketshare numbers speak volumes. Canadian consumers have shown they believe in our products and that Symantec’s repatriation of its Canadian office last year is proving to be a big hit with customers and our reseller and distribution partners," adds Monnette.
