Hello. I have an urgent problem with my windows 7. I know someone had a similar one, but it is not the only thing that goes wrong. My AVG continuously finds on my computer Trojan Horse Crypt.AQLW. It shows every feew minuts the monit, that some .dll file in C:\windows\system32 (each time it is a different file (e.g. now it is comhost.dll) The monit also says that it concerns process \\.\globalroot\SyStemRoot\system32\svchost.exe It seems that AVG finds and deletes/puts to Quarantine each of those files, but it is really disturbing as it pops up very often. Also, I'm afraid if it is something really serious or not that bad? Moreover, my windows has just lost its wallpaper - it went black and as it cannot see picture files. I am quite green at that stuff, could you, please walk me through this log stuff - I haven't done it before. Could you help me, please?
