It is better to scan xp computer with an anti virus sw. If u have u may try this. But the sw is legal copy then it works well.
If u don’t have right now, then download MWAV 12.0 (its free and believe me it works 100%), only one antivirus sw that comes freely and works very well.
Just double_click the MWAV icon and it removes all spyware / virus ….. before doing that goto safe mode without networking be pressing F8 at the time of booting.
Hope it helps u!
Malware programs are very clever and have the ability to modify and bypas most antimalware installed into your computer system. The best you can do is to puchase a full license antivirus and antimalware software like Norton Antivirus and AdAware Antimalware.
