Dubai: Virus attacks have increased to a certain extent that officials in Dubai have warned computer users to be alert and vigilant.

"Don't connect to wireless network and your computer doesn't have programme, it's possible to get virus or worm e-mail," the Dubai Police tweeted on Sunday.

Nick Black, technical manager, Trend Micro, told Gulf News that lot of activities are taking place and the attacks are not targeted at specific networks.

He said that for the last few days, a virus from China has been floating around and is targeting users in India and China. Since many Indian companies are based in Dubai, they need to be extra careful, he said.
