Virus????????????????????????

do this , turn of pc , wait , switch back on and as soon as you do start tapping F8 at the top off your keyboard , you will see a few options , click SAFE MODE , Then download Malwarebytes anti-malware and run a full scan (still in safe mode) then remove all infections , run your anti virus (all still in safe mode) if you do not have an anti virus then download AVG and run a scan , after that reboot your computer as normal and thats it removed , also download SUPERAntiSpyware free edition for the future (they are all freeware) , oh it will take a while for the scans to run but be patient as it will clean it and speed up your pc
