The symptom? The virus has cause monitor to be blur and blank for a while and then after that, AVG anti virus program has gone and cannot use any anti virus to scan for viruses. I was surprise because when I check the computer, the AVG anti virus program that I've installed previously was gone. I've check the folder for AVG, and it's still there, but no executable program in the folder. In "Restricted by Bro Act" virus case, it prevent me from installing any anti virus, and also prevent me from opening any browser/folder that has anti virus/remover keywords in it. What a genius! It makes me want to learn how these people write the virus program.
I've found a forum from PC World that discussing about the possibility for a memory card to transfer virus. One of moderator in the forum wrote that it is possible for a memory card to transfer viruses. Plus he said that we will be fine as long as we have an anti virus with active scan feature in our computer.
I search the net and found several solution to overcome this virus. One of the manual solution can be found here from howto.redcomputer.net. Another easy step is to download this removal tools.
