MANIFEST Files are they viruses/spyware or adware ?

​ well i was wondering for anyone who can tell me .....ive been using the troublshooting guide from the previous problems i had with my computer ...containing the stop blue screen message : STOP 0x00000050 .....after awhile .....i was in the system32\drivers folder to find any spyware files.... i suspect i found 2 .sys files (files containing no information of file version , desc , copyright , company name , or product name . ) and changed the name to malware1.old to 2.old etc......but i knew theres "more that meets the eye" . so i checked other files in that folder not containing the .sys file type and found these files : ​

​ ​

​ eapci2m.ecw ​

​ ativmc20.cod ​

​ cxthsfs2.cty ​

​ netwlan5.img ​

​ ​

​ these files doesnt consist of any type of information of file version , description , company name copyright , or product name . Now Wouldnt it make sense for a company to tab in all there information on any of there files ?? ​

​ ​

​ same goes for the system32 folder , while searching through the folder to find any files consisting of muspd.exe files (spyware file) ...i found other files such as : ​

​ ​

​ yuk or yum 7adsfas1.ico ​

​ virus hunter yeah1.ico ​

​ moviesorangecirc1.ico ​

​ kas pink123.ico ​

​ ​

​ i thought these files i thought were abnormal , by just looking at the image of the file ...i also checked on hidden files previously followed by the trouble shotting guide for the system32/drivers folder , and guess what , i did find hidden files attributes as RHAC and MANIFEST type file consisting file sizes of 1kb, such of these files consist of the names : ​

​ ​

​ cdplayer.exe.manifest ​

​ logonui.exe.manifest ​

​ ncpa.cpl.manifest ​

​ nwc.cpl.manifest ​

​ sapi.cpl.manifest ​

​ windowslogon.manifest ​

​ wuaucpl.cpl.manifest ​

​ ​

​ ...now would any of these files that describe themselves as MAINFEST type files be normal ?? same goes for the previous files i have mentioned..... i wanna fix this problem as Soon as possible , so i would make sure that i would never have that 0x0000050 STOP blue screen message again . ​

​ Thank You for understanding. ​
