Dubai, Apr 2 (IANS): A computer virus from China has been targeting users in India as well as in China, and as many Indian companies are based in Dubai in the United Arab Emirates (UAE), they need to be "extra careful", an expert has said.

Virus attacks on computers have increased to such an extent that officials in Dubai have warned computer users to be alert and vigilant, the Gulf News reported.

"Don't connect to wireless network and your computer doesn't have programme, it's possible to get virus or worm e-mail," Dubai Police wrote on micro-blogging website Twitter.

Nick Black, technical manager of Trend Micro, a computer security company, told Gulf News that the attacks were not targeted at specific networks.

He said that in 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.
