Anyone with an Android phone in their pocket might be wise to check and see if any recently downloaded apps are causing performance issues and slowing things down.It has been confirmed by the experts at Check Point that a large-scale Android adware campaign has been targeting users worldwide, and becoming a victim could prove highly irritating.Although this latest bug doesn't steal personal data or bank details, it can silently drain resources and disrupt normal phone use.

What makes things more worrying is that some were available via Google's official Play Store.That's why so many people have ended up downloading them.It's thought that one even reached the number two position in Google Play’s “Top Free Tools” category.Those unfortunate enough to have installed them have since complained of problems such as persistent pop-up ads, vanishing app icons when attempting to uninstall, and devices becoming slower or less responsive.
