Computer Virus Symptoms
Some computer viruses alert you to their presence by putting an unexpected message on your screen. Others are more subtle.
Things To Watch For:
Programs take longer to start or run more slowly than usual.
Disk access seems excessive for simple tasks.
Access lights turn on for non-referenced devices.
Unexplained decreases in the amount of available memory or system resources.
Programs or files mysteriously disappear.
Sudden reduction in disk space.
Your antivirus program indicates a virus is present.
An antivirus program cannot be installed on the computer or is disabled and cannot be restarted.
Executable files change size and unexplained hidden files appear.
There is a double extension on an attachment that you recently opened, such as .jpg .vbs or .gif .exe.
Keep your virus detection software updated! Virus patterns change all the time
