Does Adware resemble any kind of malicious virus?

Is Ads by Testpid harmful? Is it a virus? Can it corrupt my PC? These are common questions that many web users raise, once they face the wall of ads on their screen. Fortunately, we have some relieving news about the nature of this Adware. Despite its potential annoying behavior, such software does not contain virus-like scripts and is generally not capable of causing serious harm. Real malware (such as Trojans, Ransomware, Spyware and other nasty viruses) typically has extremely dangerous abilities such as system and data corruption, file encryption, deletion of files, theft of credentials and many more dreadful features. Adware, on the other hand, has not been related to criminal activities like the ones mentioned above so far. At its worst, this software may irritate you and decrease the quality of your web browsing, but it will not corrupt or delete anything on your machine.

Still, should you keep Ads by Testpid or have it removed?

Despite not been classified as malicious, many security experts include Adware in their list of potentially unwanted programs. The reason is, pieces like Ads by Testpid, if not harmful on their own, may still indirectly expose your system to certain security threats. In a web space full of malware, you should be very careful regarding what kind of content you interact with. Unfortunately, many criminals use popping ads, fake banners and links to spread their infections, so if you keep a software that constantly floods your screen with popping boxes, blinking links, tabs and redirecting messages, it is a matter of time to accidentally click on a potential Ransomware or a Trojan horse transmitter. With this in mind, it is generally advisable to uninstall the adware and remove its ads as a purely preventive measure. Moreover, if you do so, you will surely save yourself from unexpected browsing session interruptions, sluggishness, and unresponsiveness of the affected browser, as it will not be loaded with intrusive commercial messages anymore.
