I came to my mom's house for a visit, and noticed she had been for some month's w/o an antivirus.
I downloaded free AVG antivirus, as I was told it was good.
It detected around 48 threats on the first run.
But afterwards, we were totally unable to run Microsoft Excel, Microsoft Photo Editor, and as I ran it through a USB flash drive I've got with a program called "Cruzerlock2", which encrypts files, I cannot run this one as well. I get an error message on this program that states that window's cannot open the aplication or does no have the permits to do so or something like that.
Also, the flash drive can now only be accessed when plugging it into the computer, and if you try to open it later on through my PC and clicking on the current log i get the following error:
If anyone can help me I'll be more than gratefull for the rest of my life
Thanks a bunch!
