Hi ! Thanks for the help...My problem started with not being able to defragment my computer, then finding out that i have a trojan Fakealert that keeps coming back even after using my spyware security, and when i restart the computer trojan is back again....to not being able to install ur anti-malware ( finally found out that everytime i download the program it would be a ewf file instead of exe) thats why it wont install....but finally, i got to install the program and ran it and found 20 items infected! i deleted them and now my defragmenter is running !!!!! My question is tho......i followed ur instructions and disabled TDSSserv.sys in my device manager before i installed anti-malware....now that its working, should i enable it again? or just leave it disbaled? I notice that theres a yellow exclamation point beside it and it says something not installed or its not working properly....is that normal? or should i do something else? thanks!
