A number of problems have recently developed with my Sony Vaio laptop:

1. 'svchost' exceptions which occur after logging on;

2. URL redirection to shopping sites;

3. AVG 9.0 update failures;

3. Malwarebytes forced shutdown.

I posted the details onto the AVG forum as it seemed to be related to upgrading from AVG 8.5 to AVG 9.0 Anti-Virus Free Edition:

However, I have tried all the suggested fixes but, unfortunately, none has worked.

The symptoms seem very similar to those posted by Kenickie on this BB:

Infection that shuts down Malwarebytes, Proving very difficult to remove!

I would be very grateful for any assistance in tracking this one down - presumably it could also be logging keystrokes.

Just for information, it turns out there were a number of trojan infections (18) which seem to have been cleaned successfully by Malwarebytes.

After gleaning information from other posts, essentially the steps which worked for me were:

1. Disconnected from the internet and removed AVG 9.0 completely;

2. Rebooted;

3. Ran a scan with Malwarebytes (removing AVG 9.0 enabled it to run for more than a few seconds) and used it to fix a number of Trojans which seem to have been residing in: msacm32.drv and wuasirvy.dll (C:\windows)
There were also infected dlls in the Macromedia user download area.

4. Reconnected to the internet and updated Malwarebytes and ran a full scan again which was clear.

Hope this helps anyone else experiencing similar symptoms. A reply on the AVG forum suggests running the Malwarebytes scan in safe mode.
