今天我经常收到好多“信使服务”，内容为“STOP！WINDOWS REQUIRES IMMEDIATE ATTENTION。WINDOES HAS FOUND 47 CRIICAL SYSTEM ERRORS！
TO FIX THE ERRORE PLEASE DO THE FOLLOWING ：
1。DOWNLOAD REISTRY REPAIR FROM：HTTP：//WWW。REGPROSCAN。COM
2。INSTALL REGISTRY REPAIR
3。RUN REGISTRY REPAIR
4。REBOOT OUR COMPUTER
FAILURE TO ACT NOW MAY LEAD TO DATA LOSS AND CORRUPTION！
请问这是不是病毒？？？？
类似的“信使服务”很多，请问是不是多是病毒啊？？？
