I have Dell PC running Windows 7 Ultimate usually I used to play games on it. Couple of days ago it got infected by malware and when I web browser, suspicious websites opens up (Crypto) and some times it open 18 + websites on my PC. In addition I also experience performance issues sometime freezing and crashing while playing old games. I need suggestions regarding how to clean my Windows or I should reinstall it?
What is the exact 7-character "service tag" number on your Dell?
Does it still have all of its original hardware, or has some hardware been added to it or upgraded?
Do you have Windows 7 install media for it, and does it include Service Pack 1?
