i have a dell inspiron 6400 that had been working well, or so i thought, for the past few years. all of a sudden, today, and perhaps last night, although the computer states there is a strong wifi signal from my home router network, i have had trouble bringing up any web browsers, and if they finally appear, i still cannot access the internet. i have tried both chrome and firefox. if i check windows task manager, it shows that processes for these browsers are apparently active, and yet there is nothing visible on my screen. i am concerned that it may be deliberate.
i was able to apparently use a system restore point in safe mode--i could not do so in normal mode--and then i activated malware bytes, whose initial full scan brought up 5 potential proxy hijackers it has isolated. however, when i restarted, i got the blue screen of death, took screen shots of the issue reported, and then discovered that i still could not access the internet. i am currently running another scan, also in normal mode, to see what shows up. it is not finished, but apparently at least 4 of the 5 PUM or PUP registry issues had returned.
the few times today i was able to bring a browser screen up, it was either difficult or impossible to reach a web address. therefore, i cannot use the laptop directly. however, i can download whatever is needed here on my pc, which uses the same internet provider but which is hard wired, and use a flash drive to bring it to the laptop. or, perhaps there is something else i should try to narrow down the problem, or bring to light the malware, if indeed it is malware. perhaps there is a simple fix. i can probably also copy any results from scan programs and upload them onto this computer.
please advise. i appreciate your help, and patience.
