Computer Start-up is Slower Than Normal
Most users can tell when their computer is starting slower than normal because they know how long it normally takes for their computer to complete the start-up process. If computer users notice that their computer is taken twice as long or even longer to start-up, a virus might be the source of the problem.
Multiple Advertisement Popup Windows
When computer users are overwhelmed with advertisement popup windows that continuously appear no matter how many times the users close the popup windows, the most likely source for the problem is a virus or related issue such as spyware or malware.
Cannot Connect To The Internet
If computer users are unable to connect to the Internet or their connection is constantly lost, many times the problem can be linked to a computer virus. In addition, the odds of an Internet connection problem being related to a virus increases significantly when the source of the problem cannot be traced to a gateway, ISP, or modem issue.
For most computer users, the fight against computer viruses is a never-ending fight. However, if infected, knowing the signs of a virus can help users increase the chance of saving their computers from a computer virus.
