My Computer Seems To Be Running Really Slow And I'm Worried I Might Have A Virus Or Something On My Computer. I Keep Getting Little Pop Ups Every Now And Again Too But My Current Virus Checker Does Not Pick Anything Up. I've Heard Of 'Hijack This' But I'm Unsure As To What It Is And How To Work It?
Go through your hard disk and delete programs that you don't need, or games that you don't play. Run defragmentation and try again. It may be that you only have a slow connection, or tat your computer has too much dross to search through before finding all that it needs to work properly and quickly.
