Am not a computer expert myself but have been able to parse threads and do the needful to keep my pc working and effective, until this time.. .
The relevant history..
Win 8.1 Factory fitted (No Backup CD/DVD ever made) :-(
LENOVO G50-30 80G0
64 Bit, Anti Virus used Avast (Now uninstalled).
Other Programs installed:
Adblock plus
Also regular runs of the following:
1. Msert.exe (only to clean the malware that got in a week ago.)
2. Microsoft Anti Malware (only to clean the malware that got in a week ago.)
3. Spybot (Regular All the time)
4. Roguekiler (Adlice) only to clean the malware that got in a week ago.
5. NoScript (only to prevent the BROWSER HIJACKING from the rdsrv.com malware that got in a week ago)
Got infected with the rdsrv.com browser hijack a week ago. Downloaded various anti-malware, but couldn't get the problem out of the rootkits without causing problems. Thankfully did a restore and started again.
Realised the Avast Anti-virus I had downloaded had also invalidated the Windows Defender.
Windows Defender Would NOT Run
Security System WOULD NOT run (Despite the services.msc showing the system security in a started state.
The Boot sequence would not change because the “Your Security settings do not allow that” (even though I am the only (and the Admin) user.
Unininstalled AVAST, and by following web forums, did a sfc/scannow
Got some corrupted files (without description)
did some Dism /... Online /.. (Can't remember the whole syntex)
Windows defender finally turned on. I ran a thorough scan (after update). All good.
The Anti Virus that I downloaded (Comodo) from Downloads.com would not be recognised and could not run.
NOW, the system is stuck in a startup loop. Without a recovery DVD, can’t think what to do.
