I don't know what to make of this but allow me to share this one with all of you. I have a Logitech QuickPro 4000 webcam. I formatted my system last December and it has been working great. I never re-installed my webcam so last night I thought I'd download the latest drivers from Logitech. Their latest version is 8.4.6 build 1016. As I was running the setup, Webroot Spy sweeper popped up and indicated some files were suspicious. I saw that a few were Logitech so I kept those, except for one that had no details. The file name was grp.conv. Before I did anything else, I opened up a browser and went to Google. Apparently this is a Trojan. So I told Spy sweeper to remove it. The install went fine, but something told me to run AVG. I have the free edition. AVG found 8 files infected with a virus called jar/java and in the file name something that said Class. Then AVG stopped and another window showed only 6 viruses, 2 of which could have been moved to the vault, but the other 4 were embedded in Documents. I tried to search for them, but nothing came up. I didn't format, nit just yet. What I did do, I uninstalled AVG and ordered Norton. I want to give that a try and see if it might clean it out. Has this happened to anyone else where you run a download from a company's website and zingo you get a virus? I sent the webmaster an E-mail, sine Logitech doesn't seem to have an E-mail for tech support. They replied and asked me to follow the support links, which I did, but no E-mail capability.
Oh, before I forget. I ran AVG the night before last and there were no viruses. I didn't download anything as far as I can remember when the last download was, which I think was a critical update from Microsoft. I have to conclude that Logitech had something on that file. I only want to make them aware so that they can check into it.
