IS THIS COMPUTER INFECTED? HOW CAN I TELL?
1 - Computer is running unusually slow or your internet connection seems to be significantly slower than normal or drops the connection intermittently.
2 - Getting pop-ups with advertising while you are browsing the web, and sometimes even if you don't have a web browser open.
3 - Your web browser constantly redirects you to sites that look like spam or advertising, while common and legitimate search portals like Google or Bing are replaced with malicious search portals.
4 - While browsing, the browser behaves oddly, such as words on web pages suddenly turning into links for advertising.
5 - Friends report getting strange emails from the you that you don't remember sending.
6 - Computer becomes unusable or you can't access your programs, or your icons get replaced with junk you didn't even install.
