The report found that the number of virus attacks on personal computers reached 1 billion in the first half of the year, a 30% increase compared with the previous six months from July to December 2016. Statistics from Tencent's anti-virus laboratory from 2014 to 2017 showed that the number of malware programs continued to increase. Shenzhen topped the list of locations with the most virus attacks, followed by Chengdu and Guangzhou, according to the report, which added that cities and regions with higher internet popularity might face higher risks of virus attacks.
