Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

Adware-Wyyo is a Trojan adware that creates pop-up advertisements for the purposes of marketing other malware as malicious as itself, or even worse. Besides undesirable marketing, it will invade Internet Explorer and may cause general instability in your system. Any signs of Adware-Wyyo on a computer should be responded to by deleting Adware-Wyyo either manually or through the assistance of security software.

The Start of Adware-Wyyo
Adware-Wyyo first appeared around 2009, with the greatest number of infections centered in China and the United States. Its primary means of infection is currently poorly documented, but is likely to be through infection of .exe files, which are then spread throughout the Internet in various ways, such as P2P programs and malicious website code.
The Outer Workings of Adware-Wyyo's
Adware-Wyyo may not always come alone. Adware-Wyyo may be bundled with infections such as rogue anti-spyware programs. This combination is especially potent because Adware-Wyyo, as adware, is likely to advertise for these rogue programs that throw up an outer pretense of being useful system-maintenance tools. Don't mistake these rogue programs for the real thing!
The primary sign of Adware-Wyyo or similar adware consists of a deluge of pop-ups, which may persist even with your browser closed, or if you're using an unusual browser. Other common attacks consist hijacking your browser forcibly through an Internet Explorer plug-in, altering your browser's settings (particularly your designated home page), and a heavy reduction in the speed of your system's performance. Adware-Wyyo has also been reported to deal out far nastier problems as well, almost as lethal afterthoughts. Other characteristics:
- Adware-Wyyo may download and run malware automatically, without your consent or knowledge
- Adware-Wyyo may also serve as spyware by recording the browsing habits and other information of the user and then sending that information to criminals.
- Adware-Wyyo will create an entry in your registry to cause Adware-Wyyo to start every time Windows is started under ordinary conditions.
- Adware-Wyyo will register a DLL file, which may be used to make your computer vulnerable and deliver or run malware besides Adware-Wyyo.
