Recently I was infected with a trojan that was redirecting my web searches. I came here to get some assistance in having it removed, and we got rid of most of it.

But I think there is a trace of it left.

At first I noticed my windows firewall was shut off after a reboot. And I would turn it back on manually and it would be fine for a few days.

But now my PC is locking up at restart, just after my programs load. If I restart the PC manually a few times it will load up without locking up.

I have not installed any type of new programs recently so I think this is Infection Related.


I tried to do a system restore in safe mode but after I did that the PC was still Locking up after reboot.


I think the infection may be hiding in System Restore so I tried to turn it off and a message popped up that said windows could not release it and that I needed to restart.


Iam gonna try to clear the system restore. Right now iam running Anti malware Bytes full scan.

I have ran Kaspersky AV , Spy Sweeper, Ad Aware and Spy Bot


Anyone have any ideas ?

Please post the Malwarebytes log.

Ok, I just ran the SDfix in safemode.

It removed a couple of entries and now iam seeing a different behavior on my PC.

When I restart and load up windows my programs will load up but the PC locks up for about 1 min after they all load. Then it Free's up sometimes and I can open programs start menu ect like normal.

Before it was staying locked up after reboot.


Ive just now restarted my PC about 15 times watching how it is behaving. Rarely it will load up and not have any lock up / freeze problems.


But the majority of the time its freezing up for about a min then freeing up. :thumbsup:

A delay during startup can be caused by a mapped network drive that is no longer available.

Ok I ran the Cleaner and the Scanner in Safe Mode. The Scanner removed 2 entries. Then I restarted the PC, it did not Lock up :thumbsup:


So I just restarted about 3 times and each time it started up with no lockups.


Problem Seems to be resolved.

Thanks for your Assistance :flowers:
