The answer is adware, as the symptoms of popup advertisements appearing without a browser and a fake system process like 'svch0st.exe' consuming 95% CPU are classic indicators of this malware type. Adware is designed to generate revenue by displaying intrusive ads, and it often disguises itself by using misspelled names of legitimate Windows processes—such as replacing the 'o' in 'svchost.exe' with a zero—to evade casual detection. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your ability to differentiate adware from other malware like trojans or spyware, with a common trap being to misidentify the high CPU usage as a virus or resource leak. Remember that adware’s primary goal is ad delivery, not data theft or system damage, so removal requires a dedicated anti-malware tool rather than simple process termination. A helpful memory tip: if it’s popping up ads and faking a system name, think “Ad-ware, not a-ware of its disguise.”

Correct answer & explanation
✓
Adware
Adware displays unwanted advertisements and often masquerades as legitimate processes. The misspelled 'svch0st.exe' mimics a Windows system process, a common adware tactic. This malware type is best removed using a dedicated anti-malware tool.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Ransomware
Why it's wrong here
Ransomware encrypts files and demands payment, but does not typically cause pop-up ads or mimic system processes.
✓

✗
Rootkit
Why it's wrong here
Rootkits hide deep in the OS to conceal other malware, but they do not directly cause pop-up ads.
✗
Spyware
Why it's wrong here
Spyware steals data silently; while it may slow a system, it rarely generates pop-up ads.

Variation 1. A customer reports that their Windows 10 computer is running very slowly, and they see frequent pop-up ads even when no browser is open. They also notice a new toolbar in their browser that they did not install. What type of malware is most likely causing these symptoms?
easy
A.Ransomware
✓ B.Adware
C.Virus
D.Worm
Why B: Adware displays unwanted advertisements and often installs browser toolbars, slowing down the system. Unlike a virus or worm, adware does not self-replicate, and ransomware would demand payment rather than show ads.
