Here's the story: I can't give you a precise information on this, but about a week now I am unable to download anything on my PC, whether I try to download with Chrome, Firefox or IE. All the downloads finish successfully, but they are always deleted afterwards, whether they are from secure websites or not; for example, Chrome tells me "Virus Detected" after a download is completed, Firefox and IE downloads simply vanish. I've disabled my antivirus program (which happens to be the paranoiac AVG, ironically)during my later attempts to download anything from the webs, no change. After a thorough scan, I did find some cookies and a few of the usual trojans AVG finds in it's scans, healed/deleted them, same result. Updates work, interestingly enough.
To me it seems it may be a web-browser related problem? Or a certain something that might prevent normal downloads, a virus, malware, trojan, worm, something AVG doesn't pick up because it's buried in deep? I wouldn't want any of my other equipment and PC's in the house to catch this thing, as my PC is basically everyone's hub at my place.
I thank everyone who took their time to read this, I hope it is informative enough, any help with this matter would be very much appreciated
