According to researchers at AppRiver who, on June 15, 2011, released the security company's Threat Landscape Report for June 2011, PC virus along with other malware activity grew during May 2011, intermittently reaching the highest level of over 10m samples daily.

The report outlines that Internet fraudsters exploited prominent news events for delivering fresh malware samples whilst online criminals kept attacking large organizations during May 2011.

Further, soon as Osama bin Laden was killed, there appeared several malevolent websites posing as providing videos and pictures of the Navy SEAL maneuver. But in reality they pulled down malicious software without drawing the user's notice. Such software associated with bin Laden's death inundated Facebook and the inboxes of Internet users, states AppRiver.

The company also states that remnants of malicious software associated with the Royal Wedding continued to surge when May 2011 started.

Moreover, there was a twofold increase during the 5th month in a row in the total number of email-borne virus messages. During May 2011, over 102m such messages were isolated, a rise of 23% since April same year.

Also according to the report, during May 2011, Russia ranked No.1 as the origin of spam mails, with the U.S, Brazil and India following.

The spam mails unleashed several scams to garner victims. These comprised those promising Patch Tuesday fixes that were actually a fake as they loaded the Zeus Trojan. Additionally, false notifications from FBI surged, delivering the Bredolab Trojan, AppRiver outlined in its report.

Unfortunately, during May 2011, there was as well the fresh malware toolkit namely Weylan-Yutani Bot released publicly. The toolkit is exclusive in that it can create scripts with which both Mac and PC systems can be infected.

AppRiver added that although malware designed for Mac had been into existence since sometime, it had still, till the present, been obtainable in the form of a toolkit. Thetechherald.com reported this on June 17, 2011.

Additionally, the report states that the above toolkit can be bought in exchange of 1,000 credits WebMoney that's equivalent to approximately USD1065, while its creators have assured of including Linux and iPad scripts shortly.
